HP NonStop H-series Operating System

HP Tweaks NonStop, HP-UX systems | true Questions and Pass4sure dumps

windows and Linux servers may likewise dominate income at Hewlett-Packard, as they achieve for the programs market at giant, but the company nonetheless has a significant company peddling NonStop and HP-UX techniques. These machines necessity care and a focus on occasion, as any product line does, and this week HP is updating the hardware for NonStop methods and the HP-UX operating materiel for its Integrity and Superdome machines.

In many ways, the NonStop weakness tolerant servers are going to Have an extended and extra entertaining future than the HP-UX machines. As EnterpriseTech reported final fall, HP has decided to port the NonStop working materiel and disbursed database administration system from its latest Itanium processors to Intel’s Xeon processors. HP has been vague about when this port can exist finished and on what specific Xeon equipment. HP is clearly in no hurry, nor does it ought to exist given the dimensions out nature of the NonStop line. The present NonStop machines can Have up to 4,080 nodes linked along with a proprietary ServerNet interconnect for a maximum of 16,320 cores running the shared-nothing relational database and its underlying NonStop kernel. Randy Meyer, director of product administration for the NonStop line, which is partake of HP’s enterprise distinguished systems division, informed EnterpriseTech closing drop that the largest account has simply over 1,000 nodes in creation. there is a number of play to scale out, naturally, with the existing product line. but just because the database cluster can scale out horizontally doesn't signify that valued clientele don’t necessity some extra vertical scaling on each and every node to allay raise the efficiency of the dispensed applications running atop NonStop clusters. (If this had been now not the case, NonStop machines would quiet exist running on MIPS processors which are about as powerful as you Have got inner your home router.)

The high-conclusion NonStop NB56000 techniques are in response to a variant of the Integrity i4 blade servers that HP announced in November 2012 wearing the “Poulson” Itanium 9500 processors, which advance in two-core and four-core variants with clock speeds operating from 1.seventy six GHz to 2.fifty three GHz. HP additionally has a low-end product that receives purchasers going on smaller clusters that are in line with much less expensive rx2800 i4 rack servers. These low-conclusion machines are what HP is updating nowadays. The NS2300 NonStop machines are according to two-core Itanium 9500 processors, while the NS2400 are in line with the four-core Itanium 9500 chips. The processors are working at the entry 1.73 GHz speed. The prior machines topped out at 32 GB of reminiscence per node but the original one is accelerated to 48 GB per node. as much as four of these machines can exist clustered perquisite into a single weakness tolerant system. With the entire tweaks between the “Tukwila” Itanium 9300 and Poulson Itanium 9500 processors, socket for socket the more moderen Itaniums carry someplace between 2X and a yoke of.4X in performance, counting on the workload. in response to the clock speeds HP has used for the NonStop machines, valued clientele will discern round a 50 % performance increase. (HP is staying far from the higher-clocking and greater costly Itanium 9500 chips.)

HP is not divulging the pricing on the NonStop machines but Jeff Kyle, director of product management for the enterprise Servers community, says that pricing for the original NB2300 and NB2400 machines based on Poulson are in the same latitude because the NB2100 and NB2200 machines in line with Tukwila. A ground NonStop 2100 machine from August 2012 cost $75,000 with two logical processors in two sever physical nodes with eight GB of recollection on each and every node; that machine additionally included six system disks (that’s three mirrored volumes) and six information disks (triple mirrored as neatly for secure conserving). That materiel has the NonStop kernel rate however the NonStop database will can saturate you an extra $13,000 for an annual license. The entry gadget additionally runs the ServerNet clustering atop Ethernet, which cuts expenses.

The element that HP specializes in with the NonStop line is that it no longer only presents incredible scalability for database purposes, however that the weakness tolerance is enhanced than which you can regain with a cluster of Linux servers running databases in a inordinate availability mode. in case you occupy an Oracle actual application Clusters setup, says Kyle, you may exist able to propel it to three or 4 nines of availability (that’s ninety nine.9 p.c or ninety nine.ninety nine p.c uptime, which is, respectively, four.4 hours or 52.3 minutes of downtime per 12 months). but, contends Kyle, that you could regain five nines of availability, or just around 5 minutes of downtime per 12 months, with a NonStop cluster ­– and achieve so at a 25 p.c subside cost. That evaluation comes from certainly one of HP’s system integrators in Europe who desires to tarry anonymous and who builds fee techniques on both NonStop weakness tolerant clusters and greater commonplace Linux clusters. HP continues a low-conclusion materiel around to regain valued clientele hooked on the iron and then to grow with them. there's a judgement these venerable Tandem machines persist and when HP at ultimate gets NonStop ported over to Xeon processors and ServerNet operating atop InfiniBand it is going to exist practicable to ramp up the assign in base.

Ideally, HP would Have carried out this lengthy for the judgement that when it grew to exist obvious that Itanium was a lifeless end, however the enterprise wanted to store pan in its combat within the press and then within the courts with Oracle over the portion of the Itanium processor. HP has no longer gained damages in its lawsuit as of yet and hence it is going to achieve nothing to disparage the chip. but the future “Kittson” Itanium, due in everybitof probability this yr or next, is not anticipated to present purchasers an Awful lot within the means of core count number or efficiency boosts. What become once a plot to achieve a more aggressive redecorate of the Itanium with the Kittson 9700 collection – together with socket compatibility with the Xeon E7s – now looks to exist some modest architectural tweaks on the current Itanium 9500s and no more socket compatibility.

HP’s techies Have proposed porting the venerable HP-UX Unix variant to Xeon processors a few instances but every time the hassle turned into shot down by means of the top brass on the business for explanations it has not defined. It is not arduous to figure. For probably the most half, NonStop valued clientele write their personal functions, most frequently in Java nowadays, so relocating their applications from Itanium to Xeon is not a stout deal. The Java stack takes care of most of it and HP is providing a source code assure for those that utilize different NonStop compilers to jot down their code. On HP-UX, besides the fact that children, most shoppers are the utilize of an Oracle database and third celebration applications, often from Oracle or SAP. It appears impossible that any of the device utility suppliers will achieve ports of their code to HP-UX on Xeon given the quite small base. SAP has clearly tied its future to Xeon E7 machines working SUSE Linux and its HANA in-reminiscence database and Oracle has no activity in assisting HP-UX sell towards its own Sparc SuperCluster or Xeon Exadata “engineered techniques,” which flee its own Solaris and Oracle Linux operating techniques. If HP had finished an X86 port of HP-UX decades in the past, lengthy earlier than both SAP or Oracle were attracted to programs, there could had been an opportunity for HP-UX on Xeon and Opteron processors. realizing this, HP has in its region pitched Linux and windows on its future Xeon E7 “undertaking Odyssey” machines, so that you can scale as much as sixteen sockets and sixteen TB of main recollection in a single photo the usage of NUMA clustering.

Having talked about everybitof of that, HP-UX continues to exist a stout a partake of the workload at many world 2000 businesses and may most really exist supported until 2020, and very likely beyond that. And so HP has to supersede the working device from time to time to handle concerns that its largest valued clientele are dealing with. HP is additionally changing the pricing on its CloudSystem Matrix add-on for Integrity i4 machines to execute it affordable for companies to construct clouds in line with HP-UX.

The March 2014 update to HP-UX 11i v3, as you can discern from the unencumber notes, is the thirteenth update to this version of HP’s Unix, which is supported on Itanium-primarily based machines, and brings a “soft reboot” duty to the Integrity i4 machines. This characteristic was already available on the Superdome 2 servers in an update final 12 months. depending on the complexity of the methods utility, booting up an HP-UX desktop can occupy anyplace from several to as an Awful lot as 40 minutes, says Kyle, and this exquisite reboot characteristic can prick this time in half.

The HP-UX update likewise comprises the capability to dynamically stream workloads running inner of Integrity VMs and vPars partitions from Integrity i2 machines in line with Tukwila Itaniums to Integrity i4 machines in keeping with Poulson chips. This circulate requires no downtime. whereas Kyle is making no promises on the naming conventions, when the Kittson Itaniums are available in what they presume should exist called the Integrity i6 servers, this dynamic VM software migration characteristic can exist attainable to rush apps from the current i4 to the long flee i6 machines as smartly. HP-UX 11i v3 has additionally been modified to aid the dynamic addition of I/O, and C and C++ libraries can in a similar vogue exist sizzling swapped without taking down the device. Integrity VMs are additionally fatter with twice the digital cores (32) and twice the virtual recollection (256 GB) supported per VM. HP has already converged the administration of vPars and Integrity VM virtual machines in a previous unlock and with the March 2014 update, HP has automated the conversion process to slither vPars to Integrity VMs. The HP-UX statistics sheet has details on the previous a few releases and additionally explains the diverse versions of the HP-UX stack.

The one other change concerning HP-UX is a change in pricing for the CloudSystem Matrix cloud controller and automation device that HP sells for both its ProLiant X86 and Integrity Itanium machines. On the Itanium machines, HP used to require that customers purchase no less than eight sockets of licenses to the CloudSystem Matrix software. starting now, customers can buy a license for under two sockets. that's a pretty modest cloud by passage of any necessities, however then once more, HP-UX workloads, dote these of other Unix suppliers, scope from pretty small to significantly massive. CloudSystem Matrix will flee on relatively stale ProLiant and Integrity equipment, however Kyle says that it's really tuned to flee on Integrity i2 and i4 and ProLiant Gen7 and Gen8 packing containers.


HP presents WebLogic on OpenVMS, NonStop servers | true Questions and Pass4sure dumps

5 collaboration tools that raise Microsoft workplace

HP gears down NonStops for midrange, rising markets | true Questions and Pass4sure dumps

Hewlett-Packard's NonStop servers tolerate faults besides the fact that original CEO Meg Whitman and Wall road, which is respiratory down her neck, cannot. And now, in a hope to offset declines on its HP-UX Itanium server business and regain its NonStop Integrity machines into emerging markets, HP has trimmed down the configurations and costs on the NonStops so they are within fiscal compass of extra customers.

unlike the HP Integrity and Superdome servers that flee HP-UX and the OpenVMS variants of the Integrity machines, the NonStop platform that everybitof started out as Tandem and came to HP via its acquisition of Compaq greater than a decade in the past is one which HP absolutely controls and that Oracle cannot basically achieve a noteworthy deal to. As is the case on AIX and Solaris, Oracle's 10g and 11g databases are by using some distance the favorite databases on HP-UX and a unbiased amount of HP-UX business is pushed through Oracle's myriad utility suites. Oracle likewise controls the RDB relational database for OpenVMS, too. And clustering technology from Tru64 Unix is the underpinning of Oracle's actual utility Clusters because of a licensing occupy care of Compaq that predates the HP takeover of Compaq.

The NonStop machines utilize quick networking and clustering expertise to execute a parallel database searchfor dote a single database to functions; the application has weakness tolerance, which capacity if you lose a server node within the community, processing continues on the final nodes without crashing the utility.

With the NonStop line, economic functions, charge processing, stock exchanges, healthcare, and telecom firms (who are often legally mandated to maintain their techniques up and operating) frequently write their own applications and are neatly acquainted with the NonStop Kernel working materiel and the NonStop SQL database and at the present time are apt to exist coding apps in Java, commonly from within Microsoft's visual Studio app dev tool. Larry Ellison can compete with NonStop with Oracle RAC on Solaris or Linux, but he has no app or database or middleware levers to play here as he does with HP-UX and to a much smaller extent with OpenVMS.

it's a miracle that HP hasn't institute out that the one working gadget and database it must port to Xeons is never HP-UX, but fairly NonStop. Then HP might utilize more cost-effective Xeon iron and combine the ServerNet network clustering into the computer.

It may even exist in a position to tow a Cray and assign a Linux emulation environment atop the hypothetical ServerNet infrastructure after which allow applications already compiled for X86 iron to flee unchanged on ServerNet, pondering they're on a standalone Linux container with an Ethernet stack. (here is a partake of the Cray Linux atmosphere, which masks the underlying "SeaStar" and "Gemini" interconnects from supercomputer applications.)

i could slither one further and recount that perhaps HP needs to purchase Cray above everybitof for this Linux layer and build a wholly original server company from Cray and Tandem. This ported NonStop atmosphere would, for instance, slither very properly with the longer term "undertaking Odyssey" Xeon-based mostly servers that the company is working on.

but, regrettably, that isn't what HP is doing these days. The company is offering a geared-down NS2100 server, a comply with-on to the previously smallest NonStop gadget in the lineup, the NS2200, which HP started selling in February and which it didn't publicly announce. (i know, this makes no sense.)

The NonStop 2100 is in keeping with the rx2800 i2 rack-mounted server, which debuted again in April 2010 with the relaxation of the Integrity and Superdome servers carrying Intel's "Tukwila" quad-core Itanium 9300 processors. this is a two-socket server, just dote the blade servers that other Integrity machines are, however HP only puts one processor in the device and, counting on the mannequin, handiest activates one, two, or four cores in that single socket.

This might likewise sound ordinary, but it means HP only has to buy one chip from Intel to execute a various line of machines – in the case of the entry NonStop machines, that would exist the 1.33GHz Itanium 9320 processor, which has 16MB of L3 cache and costs half as tons as the excellent-bin 1.73GHz half.

NonStop NS2100 weakness tolerant server

NonStop NS2100 weakness tolerant server

by the way, in keeping with Randy Meyer, director of product administration for the NonStop line within HP's enterprise essential techniques division, you cannot spark off those dormant cores in an NS2100 or NS2200 node. So achieve not grief attempting. (You necessity at the least two nodes to exist weakness tolerant.) in preference to the usage of the high-conclusion ServerNet clustering that's on the heart of the higher NonStop machines, HP has cooked up a variant cluster know-how known as extend-over-IP that enables touchstone Gigabit Ethernet links and outboard switches for linking I/O, storage, and telecom switching systems.

The NonStop machines create a logical processor, which can Have from two to 4 cores and hence from two to 4 nodes. These logical processors can Have from 8GB to 32GB of logical memory, and they're then linked with the expand-over-IP network stack into a larger cluster over the Gigabit Ethernet backbone implemented by the IP Cluster I/O module, or I/O CLIM for brief. as much as 1,020 logical processors can likewise exist linked collectively into a single weakness tolerant cluster with a highest of 32TB of reminiscence and up to four,080 Itanium cores across that cluster.

There are Storage CLIMs to link to storage – during this case, arrays with as much as 200 disk drives – and if you are within the telco racket, the Telco CLIM to link into switching systems. The NS2100 can Have up to 6 of those CLIMs in its networks. in the intervening time, the NS2100 ships in a 42U rack, however Meyer says a more compact 36U gadget is coming inside a few months.

You should exist would becould very well exist considering, how can a NonStop cluster flee over Gigabit Ethernet? neatly, the sorts of functions that consumers are likely to flee on NonStop machines customarily Have loads of tiny transactions. "or not it's now not dote you are pitiable round images of your dog," says Meyer with a chortle.

With the NonStop NS2200 entry gadget that debuted in February, everybitof of the feeds and speeds are the same except that each and every rx2800 i2 server has two of its 4 cores activated, and for this judgement which you could carry roughly twice the computing capacity to suffer across these 1,020 logical processors and 32TB of leading memory.

With the NonStop BladeSystem NB54000c machines that were announced in March 2011, the nodes are clustered along with appropriate ServerNet switches and utilize the IP, Storage, and Telco CLIMs to consult with the outdoor world. The NB54000c has a logical node comprised of two blade servers and it will probably extend up to sixteen blade servers. every blade is actually a two-socket on the Integrity BL860c i2 blade server, and once again there is only one physical processor installed on the blade.

shoppers can Have two or four cores on the Itanium 9340 activated; they spin at 1.6GHz. The excessive-end bladed NonStop makes utilize of the same c7000 chassis as ProLiant and Integrity blade servers, and it could scale as much as 255 logical processors to a complete of four,080 physical blades with as much as sixteen,320 Itanium cores in a single cluster. The greater box can aid 48 CLIMs and a pair of,four hundred SAS disks or 60 I/O Modular Enclosure adapters (from the old-trend NonStops) with three,248 Fibre Channel disks for storage.

The NS2100 and NS2200 flee the equal NonStop J-series operating gadget, which was tweaked to flee on multicore Itanium processors, as the bigger NonStop BladeSystem machines. (The latest supported unlock on the NS2100 is J06-14.)

A ground configuration of the NS2100 gadget comes with two logical processors in two nodes, 8GB of reminiscence in every node, six device disks (with three mirrored volumes) and six records disks (once again in three mirrored volumes. The machine comes with the NonStop Kernel working system, however not the NonStop SQL database (no longer everybitof valued clientele utilize the database, in keeping with Meyer) and charges $75,000 with a one-year license to NonStop Kernel. if you necessity to add NonStop SQL, an annual license will flee you round $13,000, counting on aspects.

this is significantly less towering priced than the NS2000 rack-primarily based machine that HP announced lower back in March 2009 using the twin-core Itanium 9100 processors. A ground NS2000 with two logical processors (four cores, not two intellect you) and 16GB of reminiscence across those two nodes ran about $a hundred twenty five,000 for the hardware, and the NonStop application stack introduced a further $one hundred,000 to $a hundred twenty five,000 on upright of that. name it $225,000 at the midpoint. The NS2100 has about 35 per cent much less oomph, but at $88,000 charges about 60 per cent less. that's a big growth in bang for the buck. (I feel HP may achieve enhanced with Xeon iron, but it surely would require software investment to regain Itanium and MIPS emulation to drudgery on Xeons.)

That NS2100 likewise prices a noteworthy deal less than an NB54000c setup, and here is what is essential for small and midrange purchasers in addition to companies and govt organizations in emerging markets that don't necessity the total processing and that i/O capability of the NonStop BladeSystem but who want weakness tolerance just the identical. reckoning on hardware and utility configuration, an entry NB54000c laptop can cost as a lot as $500,000 in response to Meyer, with a touchstone ground configuration working round $325,000 for 2 logical processors.

Pricing for the NS2200 begins at beneath $150,000 for a ground computing device with a one-12 months license for NonStop Kernel.

NonStop biz is growing to be

HP does not shiver out sales of the NonStop products from different systems within the business crucial methods unit, and hence Meyer cannot regain selected about how this line is doing.

"we're starting to exist consumers, starting to exist market share, and transforming into their ISV companion ground – and we're no longer dropping customers," Meyer tells El Reg>, including that the can saturate of clustering up Linux programs for towering availability is not any more cost-effective than these original NS2100 machines and that is why HP has been able to grow the NonStop installed base. "purchasers treasure their NonStop machines and they flee them continuously and ever."

HP is not yet ready to argue its plans for the upcoming eight-core "Poulson" Itanium 9500 processors from Intel, so as to scale from 1.73GHz to 2.53GHz. If HP goes with the eight-core Itanium 9550 half working at 2.4GHz, it may drop these into the NS2100 and NS2200 machines and increase performance with the aid of round 50 per cent – even after turning off seven of the eight cores, as crazy as that sounds.

Meyer says that HP will roll the Poulson chips into the NonStop BladeSystem machines first after which cascade it down the road at some later date. So in case you necessity an entry NonStop desktop, there isn't a point in ready. The Tukwila variants are the only ones that could exist accessible except perhaps the center of next 12 months, they guess. ®

HP Updates Himalaya Servers

Future's so bright

One of the worries of Compaq customers after the merger with Hewlett-Packard Co. is the future of server products such as the Alpha processor and the OpenVMS operating system. With its announcement of its updates to the NonStop server line, HP gave an indication for the future of one of its product lines.

The former Compaq Computer Corp. acquired the NonStop server line with its purchase of Tandem in 1997. NonStop is a line of High-Availability (HA) servers used in Datacenter applications such as flight reservations or credit card transactions.

This week’s refresh updates the CPU used in the NonStop line. The original top-tier NonStop 86000 machine will utilize the MIPS R14000 processor. HP likewise updated its older line, giving the original S76 machines the R14000. Older machines, such as the S74000 used MIPS’ R12000.

HP likewise updated other hardware in the NonStop server line. The original servers can champion more memory, up to 16GB per processor. Faster storage systems were likewise introduced, which HP says improves I/O performance by 25%.

A clearer indication that HP has plans for the former tandem machines is the software updates. HP introduced a original version of the NonStop SQL/MX relational database, version 1.5. It likewise brought the autochthonous software in line with current Java standards. HP likewise partnered with Radiant Logic Inc. to bring autochthonous directory services to the NonStop platform.

Finally, HP signaled its intent to bring NonStop’s software into the Web Services age. It will champion SOAP, WSDL, and other components of the Web services stack in future software releases. It likewise announced a partnership with EAI heavyweight TIBCO for enterprise integration opportunities.

The high-end S76000 and low-end S760 servers are available today, with other servers arriving in the third quarter. HP will hold a conference summon Monday to further clarify its vision for the NonStop line.

    COMPUTINGFrom...Network World Fusion networking

    January 24, 2000Web posted at: 12:11 p.m. EST (1711 GMT)

    by John Bass and James Robinson, Network World Test Alliance

    (IDG) -- It everybitof boils down to what you're looking for in a network operating system (NOS).

    Do you want it spare and elastic so you can install it any passage you please? Perhaps administration bells and management whistles are what you necessity so you can deploy several hundred servers. Or maybe you want an operating system that's robust enough so that you sleep dote a baby at night?

    The ample advice is that there is a NOS waiting just for you. After the rash of recent software revisions, they took an in-depth searchfor at four of the major NOSes on the market: Microsoft's Windows 2000 Advanced Server, Novell's NetWare 5.1, Red Hat Software's Linux 6.1 and The Santa Cruz Operation's (SCO) UnixWare 7.1.1. Sun declined their invitation to submit Solaris because the company says it's working on a original version.

    Microsoft's Windows 2000 edges out NetWare for the Network World Blue Ribbon Award. Windows 2000 tops the domain with its management interface, server monitoring tools, storage management facilities and security measures.

    However, if it's performance you're after, no product came near to Novell's NetWare 5.1's numbers in their exhaustive file service and network benchmarks. With its lightning-fast engine and Novell's directory-based administration, NetWare offers a noteworthy ground for an enterprise network.

    We institute the latest release of Red Hat's commercial Linux bundle led the list for flexibility because its modular design lets you pare down the operating system to suit the job at hand. Additionally, you can create scripts out of multiple Linux commands to automate tasks across a distributed environment.

    While SCO's UnixWare seemed to lag behind the pack in terms of file service performance and NOS-based administration features, its scalability features execute it a tough candidate for running enterprise applications.

    The numbers are in

    Regardless of the job you saddle your server with, it has to achieve well at reading and writing files and sending them across the network. They designed two benchmark suites to measure each NOS in these two categories. To reflect the true world, their benchmark tests consider a wide scope of server conditions.

    NetWare was the hands-down leader in their performance benchmarking, taking first region in two-thirds of the file tests and earning top billing in the network tests.

    Red Hat Linux followed NetWare in file performance overall and even outpaced the leader in file tests where the read/write loads were small. However, Linux did not achieve well handling big loads - those tests in which there were more than 100 users. Under heavier user loads, Linux had a current to discontinue servicing file requests for a short epoch and then start up again.

    Windows 2000 demonstrated needy write performance across everybitof their file tests. In fact, they institute that its write performance was about 10% of its read performance. After consulting with both Microsoft and Client/Server Solutions, the author of the Benchmark Factory testing implement they used, they determined that the needy write performance could exist due to two factors. One, which they were unable to verify, might exist a practicable performance problem with the SCSI driver for the hardware they used.

    More significant, though, was an issue with their test software. Benchmark Factory sends a write-through flag in each of its write requests that is supposititious to cause the server to update cache, if appropriate, and then accommodate a write to disk. When the write to disk occurs, the write summon is released and the next request can exist sent.

    At first glance, it appeared as if Windows 2000 was the only operating system to deference this write-through flag because its write performance was so poor. Therefore, they ran a second round of write tests with the flag turned off.

    With the flag turned off, NetWare's write performance increased by 30%. This test proved that Novell does indeed deference the write-through flag and will write to disk for each write request when that flag is set. But when the write-through flag is disabled, NetWare writes to disk in a more efficient manner by batching together contiguous blocks of data on the cache and writing everybitof those blocks to disk at once.

    Likewise, Red Hat Linux's performance increased by 10% to 15% when the write-through flag was turned off. When they examined the Samba file system code, they institute that it too honors the write-through flag. The Samba code then finds an optimum time during the read/write sequence to write to disk.

    This second round of file testing proves that Windows 2000 is dependent on its file system cache to optimize write performance. The results of the testing with the write-through flag off were much higher - as much as 20 times faster. However, Windows 2000 quiet fell behind both NetWare and RedHat Linux in the file write tests when the write-through flag was off.

    SCO honors the write-through flag by default, since its journaling file system is constructed to maximize data integrity by writing to disk for everybitof write requests. The results in the write tests with the write-through flag on were very similar to the test results with the write-through flag turned off.

    For the network benchmark, they developed two tests. Their long TCP transaction test measured the bandwidth each server can sustain, while their short TCP transaction test measured each server's capacity to handle big numbers of network sessions with small file transactions.

    Despite a needy showing in the file benchmark, Windows 2000 came out on top in the long TCP transaction test. Windows 2000 is the only NOS with a multithreaded IP stack, which allows it to handle network requests with multiple processors. Novell and Red Hat recount they are working on integrating this capability into their products.

    NetWare and Linux likewise registered tough long TCP test results, coming in second and third, respectively.

    In the short TCP transaction test, NetWare came out the clear winner. Linux earned second region in spite of its need of champion for abortive TCP closes, a system by which an operating system can quickly rend down TCP connections. Their testing software, Ganymede Software's Chariot, uses abortive closes in its TCP tests.

    Moving into management

    As enterprise networks grow to require more servers and champion more End users, NOS management tools become crucial elements in keeping networks under control. They looked at the management interfaces of each product and drilled down into how each handled server monitoring, client administration, file and print management, and storage management.

    We institute Windows 2000 and NetWare provide equally useful management interfaces.

    Microsoft Management Console (MMC) is the glue that holds most of the Windows 2000 management functionality together. This configurable graphical user interface (GUI) lets you snap in Microsoft and third-party applets that customize its functionality. It's a two-paned interface, much dote Windows Explorer, with a nested list on the left and selection details on the right. The console is facile to utilize and lets you configure many local server elements, including users, disks, and system settings such as time and date.

    MMC likewise lets you implement management policies for groups of users and computers using vigorous Directory, Microsoft's original directory service. From the vigorous Directory management implement inside MMC, you can configure users and change policies.

    The network configuration tools are institute in a sever application that opens when you click on the Network Places icon on the desktop. Each network interface is listed inside this window. You can add and change protocols and configure, enable and disable interfaces from here without rebooting.

    NetWare offers several interfaces for server configuration and management. These tools offer duplicate functionality, but each is useful depending from where you are trying to manage the system. The System Console offers a number of tools for server configuration. One of the most useful is NWConfig, which lets you change start-up files, install system modules and configure the storage subsystem. NWConfig is simple, intuitive and predictable.

    ConsoleOne is a Java-based interface with a few graphical tools for managing and configuring NetWare. Third-party administration tools can plug into ConsoleOne and let you manage multiple services. They reason ConsoleOne's interface is a bit unsophisticated, but it works well enough for those who must Have a Windows- based manager.

    Novell likewise offers a Web-accessible management application called NetWare Management Portal, which lets you manage NetWare servers remotely from a browser, and NWAdmin32, a relatively simple client-side implement for administering Novell Directory Services (NDS) from a Windows 95, 98 or NT client.

    Red Hat's overall systems management interface is called LinuxConf and can flee as a graphical or text-based application. The graphical interface, which resembles that of MMC, works well but has some layout issues that execute it difficult to utilize at times. For example, when you flee a setup application that takes up a lot of the screen, the system resizes the application larger than the desktop size.

    Still, you can manage pretty much anything on the server from LinuxConf, and you can utilize it locally or remotely over the Web or via telnet. You can configure system parameters such as network addresses; file system settings and user accounts; and set up add-on services such as Samba - which is a service that lets Windows clients regain to files residing on a Linux server - and FTP and Web servers. You can apply changes without rebooting the system.

    Overall, Red Hat's interface is useful and the underlying tools are powerful and flexible, but LinuxConf lacks the polish of the other vendors' tools.

    SCO Admin is a GUI-based front End for about 50 SCO UnixWare configuration and management tools in one window. When you click on a tool, it brings up the application to manage that detail in a sever window.

    Some of SCO's tools are GUI-based while others are text-based. The server required a reboot to apply many of the changes. On the plus side, you can manage multiple UnixWare servers from SCOAdmin.

    SCO likewise offers a useful Java-based remote administration implement called WebTop that works from your browser.

    An eye on the servers and clients

    One distinguished administration job is monitoring the server itself. Microsoft leads the pack in how well you can preserve an eye on your server's internals.

    The Windows 2000 System Monitor lets you view a real-time, running graph of system operations, such as CPU and network utilization, and recollection and disk usage. They used these tools extensively to determine the sequel of their benchmark tests on the operating system. Another implement called Network Monitor has a basic network packet analyzer that lets you discern the types of packets coming into the server. Together, these Microsoft utilities can exist used to compare performance and capacity across multiple Windows 2000 servers.

    NetWare's Monitor utility displays processor utilization, recollection usage and buffer utilization on a local server. If you know what to searchfor for, it can exist a powerful implement for diagnosing bottlenecks in the system. Learning the significance of each of the monitored parameters is a bit of a challenge, though.

    If you want to searchfor at performance statistics across multiple servers, you can tap into Novell's Web Management Portal.

    Red Hat offers the touchstone Linux command-line tools for monitoring the server, such as iostat and vmstat. It has no graphical monitoring tools.

    As with any Unix operating system, you can write scripts to automate these tools across Linux servers. However, these tools are typically cryptic and require a towering flush of proficiency to utilize effectively. A suite of graphical monitoring tools would exist a noteworthy addition to Red Hat's Linux distribution.

    UnixWare likewise offers a number of monitoring tools. System Monitor is UnixWare's simple but limited GUI for monitoring processor and recollection utilization. The sar and rtpm command-line tools together list real-time system utilization of buffer, CPUs and disks. Together, these tools give you a ample overall belief of the load on the server.

    Client administration

    Along with managing the server, you must manage its users. It's no flabbergast that the two NOSes that ship with an integrated directory service topped the domain in client administration tools.

    We were able to configure user permissions via Microsoft's vigorous Directory and the directory administration implement in MMC. You can group users and computers into organizational units and apply policies to them.

    You can manage Novell's NDS and NetWare clients with ConsoleOne, NWAdmin or NetWare Management Portal. Each can create users, manage file space, and set permissions and rights. Additionally, NetWare ships with a five-user version of Novell's ZENworks tool, which offers desktop administration services such as hardware and software inventory, software distribution and remote control services.

    Red Hat Linux doesn't offer much in the passage of client administration features. You must control local users through Unix consent configuration mechanisms.

    UnixWare is similar to Red Hat Linux in terms of client administration, but SCO provides some Windows binaries on the server to remotely set file and directory permissions from a Windows client, as well as create and change users and their settings. SCO and Red Hat offer champion for the Unix-based Network Information Service (NIS). NIS is a store for network information dote logon names, passwords and home directories. This integration helps with client administration.

    Handling the staples: File and print

    A NOS is nothing without the capacity to partake file storage and printers. Novell and Microsoft collected top honors in these areas.

    You can easily add and maintain printers in Windows 2000 using the print administration wizard, and you can add file shares using vigorous Directory management tools. Windows 2000 likewise offers Distributed File Services, which let you combine files on more than one server into a single share.

    Novell Distributed Print Services (NDPS) let you quickly incorporate printers into the network. When NDPS senses a original printer on the network, it defines a Printer Agent that runs on the printer and communicates with NDS. You then utilize NDS to define the policies for the original printer.

    You define NetWare file services by creating and then mounting a disk volume, which likewise manages volume policies.

    Red Hat includes Linux's printtool utility for setting up server-connected and networks printers. You can likewise utilize this GUI to create printcap entries to define printer access.

    Linux has a set of command-line file system configuration tools for mounting and unmounting partitions. Samba ships with the product and provides some integration for Windows clients. You can configure Samba only through a cryptic configuration ASCII file - a sedate drawback.

    UnixWare provides a elastic GUI-based printer setup implement called Printer SetUp Manager. For file and volume management, SCO offers a implement called VisionFS for interoperability with Windows clients. They used VisionFS to allow their NT clients to access the UnixWare server. This service was facile to configure and use.

    Storage management

    Windows 2000 provides the best tools for storage management. Its graphical Manage Disks implement for local disk configuration includes software RAID management; you can dynamically add disks to a volume set without having to reboot the system. Additionally, a signature is written to each of the disks in an array so that they can exist moved to another 2000 server without having to configure the volume on the original server. The original server recognizes the drives as members of a RAID set and adds the volume to the file system dynamically.

    NetWare's volume management tool, NWConfig, is facile to use, but it can exist a Little confusing to set up a RAID volume. Once they knew what they were doing, they had no problems formatting drives and creating a RAID volume. The implement looks a Little primitive, but they give it towering marks for functionality and ease of use.

    Red Hat Linux offers no graphical RAID configuration tools, but its command line tools made RAID configuration easy.

    To configure disks on the UnixWare server, they used the Veritas Volume Manager graphical disk and volume administration implement that ships with UnixWare. They had some problems initially getting the implement to recognize the drives so they could exist formatted. They managed to drudgery around the disk configuration problem using an assortment of command line tools, after which Volume Manager worked well.


    While they did not probe these NOSes extensively to expose any security weaknesses, they did searchfor at what they offered in security features.

    Microsoft has made significant strides with Windows 2000 security. Windows 2000 supports Kerberos public key certificates as its primary authentication mechanism within a domain, and allows additional authentication with smart cards. Microsoft provides a Security Configuration implement that integrates with MMC for facile management of security objects in the vigorous Directory Services system, and a original Encrypting File System that lets you designate volumes on which files are automatically stored using encryption.

    Novell added champion for a public-key infrastructure into NetWare 5 using a public certificate schema developed by RSA Security that lets you tap into NDS to generate certificates.

    Red Hat offers a basic Kerberos authentication mechanism. With Red Hat Linux, as with most Unix operating systems, the network services can exist individually controlled to increase security. Red Hat offers Pluggable Authentication Modules as a passage of allowing you to set authentication policies across programs running on the server. Passwords are protected with a shadow file. Red Hat likewise bundles firewall and VPN services.

    UnixWare has a set of security tools called Security Manager that lets you set up varying degrees of intrusion protection across your network services, from no restriction to turning everybitof network services off. It's a ample management time saver, though you could manually modify the services to achieve the same result.

    Stability and weakness tolerance

    The most feature-rich NOS is of Little value if it can't preserve a server up and running. Windows 2000 offers software RAID 0, 1 and 5 configurations to provide weakness tolerance for onboard disk drives, and has a built-in network load-balancing feature that allows a group of servers to searchfor dote one server and partake the same network name and IP address. The group decides which server will service each request. This not only distributes the network load across several servers, it likewise provides weakness tolerance in case a server goes down. On a lesser scale, you can utilize Microsoft's Failover Clustering to provide basic failover services between two servers.

    As with NT 4.0, Windows 2000 provides recollection protection, which means that each process runs in its own segment.

    There are likewise backup and restore capabilities bundled with Windows 2000.

    Novell has an add-on product for NetWare called Novell Cluster Services that allows you to cluster as many as eight servers, everybitof managed from one location using ConsoleOne, NetWare Management Portal or NWAdmin32. But Novell presently offers no clustering products to provide load balancing for applications or file services. NetWare has an intricate recollection protection scheme to segregate the recollection used for the kernel and applications, and a Storage Management Services module to provide a highly elastic backup and restore facility. Backups can exist all-inclusive, cover parts of a volume or store a differential snapshot.

    Red Hat provides a load-balancing product called piranha with its Linux. This package provides TCP load balancing between servers in a cluster. There is no arduous restrict to the number of servers you can configure in a cluster. Red Hat Linux likewise provides software RAID champion through command line tools, has recollection protection capabilities and provides a rudimentary backup facility.

    SCO provides an optional feature to cluster several servers in a load-balancing environment with Non-Stop Clustering for a towering flush of fault-tolerance. Currently, Non-Stop Clustering supports six servers in a cluster. UnixWare provides software RAID champion that is managed using SCO's On-Line Data Manager feature. everybitof the touchstone RAID levels are supported. Computer Associates' bundled ArcServeIT 6.6 provides backup and restore capabilities. UnixWare has recollection protection capabilities.


    Because their testing was conducted before Windows 2000's universal availability ship date, they were not able to evaluate its hard-copy documentation. The online documentation provided on a CD is extensive, useful and well-organized, although a Web interface would exist much easier to utilize if it gave more than a yoke of sentences at a time for a particular allay topic.

    NetWare 5 comes with two manuals: a particular manual for installing and configuring the NOS with ample explanations of concepts and features along with an overview of how to configure them, and a small spiral-bound booklet of quick start cards. Novell's online documentation is very helpful.

    Red Hat Linux comes with three manuals - an installation guide, a getting started pilot and a reference manual - everybitof of which are facile to follow.

    Despite being the most difficult product to install, UnixWare offers the best documentation. It comes with two manuals: a system handbook and a getting started guide. The system handbook is a reference for conducting the installation of the operating system. It does a ample job of reflecting this painful experience. The getting started pilot is well-written and well-organized. It covers many of the tools needed to configure and maintain the operating system. SCO's online documentation looks nice and is facile to follow.

    Wrapping up

    The bottom line is that these NOSes offer a wide scope of characteristics and provide enterprise customers with a noteworthy deal of election regarding how each can exist used in any given corporate network.

    If you want a good, universal purpose NOS that can deliver enterprise-class services with everybitof the bells and whistles imaginable, then Windows 2000 is the strongest contender. However, for towering performance, enterprise file and print services, their tests pointto that Novell leads the pack. If you're willing to pay a higher charge for scalability and reliability, SCO UnixWare would exist a safe bet. But if you necessity an inexpensive alternative that will give you bare-bones network services with decent performance, Red Hat Linux can certainly fortunate the bill.

    The election is yours.
