by John Bass and James Robinson, Network World Test Alliance
(IDG) -- It outright 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 artery you please? Perhaps administration bells and management whistles are what you need so you can deploy several hundred servers. Or maybe you want an operating system that's robust enough so that you sleep relish a baby at night?
The marvelous intelligence is that there is a NOS waiting just for you. After the rash of recent software revisions, they took an in-depth eye 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 unusual version.
Microsoft's Windows 2000 edges out NetWare for the Network World Blue Ribbon Award. Windows 2000 tops the province 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 grandiose foundation for an enterprise network.
We organize 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 task 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 do it a sturdy candidate for running enterprise applications.The numbers are in
Regardless of the job you saddle your server with, it has to execute 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 existent world, their benchmark tests account a wide ambit of server conditions.
NetWare was the hands-down leader in their performance benchmarking, taking first station 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 execute well handling large loads - those tests in which there were more than 100 users. Under heavier user loads, Linux had a trend to halt servicing file requests for a short era and then start up again.
Windows 2000 demonstrated impoverished write performance across outright their file tests. In fact, they organize 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 utensil they used, they determined that the impoverished write performance could live due to two factors. One, which they were unable to verify, might live 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 putative to antecedent the server to update cache, if appropriate, and then compel a write to disk. When the write to disk occurs, the write muster is released and the next request can live 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 outright 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 organize 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 relative 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 still 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 outright 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 faculty to maneuver large numbers of network sessions with miniature file transactions.
Despite a impoverished 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 maneuver network requests with multiple processors. Novell and Red Hat condition they are working on integrating this capability into their products.
NetWare and Linux likewise registered sturdy long TCP test results, coming in second and third, respectively.
In the short TCP transaction test, NetWare came out the limpid winner. Linux earned second station in spite of its want of back for abortive TCP closes, a method 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 back more finish 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 organize 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 relish Windows Explorer, with a nested list on the left and selection details on the right. The console is simple to use 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 lively Directory, Microsoft's unusual directory service. From the lively Directory management utensil inside MMC, you can configure users and change policies.
The network configuration tools are organize in a separate 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 tender 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 mediate ConsoleOne's interface is a bit unsophisticated, but it works well enough for those who must fill 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 utensil 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 elope as a graphical or text-based application. The graphical interface, which resembles that of MMC, works well but has some layout issues that do it difficult to use at times. For example, when you elope 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 use 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 glean 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 finish 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 separate 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 utensil called WebTop that works from your browser.An eye on the servers and clients
One essential administration task 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 memory and disk usage. They used these tools extensively to determine the outcome of their benchmark tests on the operating system. Another utensil called Network Monitor has a basic network packet analyzer that lets you descry the types of packets coming into the server. Together, these Microsoft utilities can live used to compare performance and capacity across multiple Windows 2000 servers.
NetWare's Monitor utility displays processor utilization, memory usage and buffer utilization on a local server. If you know what to eye for, it can live a powerful utensil for diagnosing bottlenecks in the system. Learning the signification of each of the monitored parameters is a bit of a challenge, though.
If you want to eye 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 elevated level of proficiency to use effectively. A suite of graphical monitoring tools would live a grandiose 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 memory 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 marvelous overall understanding of the load on the server.Client administration
Along with managing the server, you must manage its users. It's no amaze that the two NOSes that ship with an integrated directory service topped the province in client administration tools.
We were able to configure user permissions via Microsoft's lively Directory and the directory administration utensil 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 tender much in the artery 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 tender back for the Unix-based Network Information Service (NIS). NIS is a store for network information relish logon names, passwords and home directories. This integration helps with client administration.Handling the staples: File and print
A NOS is nothing without the faculty to participate 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 lively Directory management tools. Windows 2000 likewise offers Distributed File Services, which let you combine files on more than one server into a separate share.
Novell Distributed Print Services (NDPS) let you quickly incorporate printers into the network. When NDPS senses a unusual printer on the network, it defines a Printer Agent that runs on the printer and communicates with NDS. You then use NDS to define the policies for the unusual 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 use 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 staid drawback.
UnixWare provides a elastic GUI-based printer setup utensil called Printer SetUp Manager. For file and volume management, SCO offers a utensil called VisionFS for interoperability with Windows clients. They used VisionFS to allow their NT clients to access the UnixWare server. This service was simple to configure and use.Storage management
Windows 2000 provides the best tools for storage management. Its graphical Manage Disks utensil 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 live moved to another 2000 server without having to configure the volume on the unusual server. The unusual 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 simple to use, but it can live a limited 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 utensil looks a limited primitive, but they give it elevated 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 utensil that ships with UnixWare. They had some problems initially getting the utensil to recognize the drives so they could live formatted. They managed to labor around the disk configuration problem using an assortment of command line tools, after which Volume Manager worked well.Security
While they did not probe these NOSes extensively to expose any security weaknesses, they did eye 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 utensil that integrates with MMC for simple management of security objects in the lively Directory Services system, and a unusual Encrypting File System that lets you designate volumes on which files are automatically stored using encryption.
Novell added back 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 live individually controlled to extend security. Red Hat offers Pluggable Authentication Modules as a artery 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 outright network services off. It's a marvelous management time saver, though you could manually modify the services to achieve the same result.Stability and failing tolerance
The most feature-rich NOS is of limited value if it can't preserve a server up and running. Windows 2000 offers software RAID 0, 1 and 5 configurations to provide failing tolerance for onboard disk drives, and has a built-in network load-balancing feature that allows a group of servers to eye relish one server and participate 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 failing tolerance in case a server goes down. On a lesser scale, you can use Microsoft's Failover Clustering to provide basic failover services between two servers.
As with NT 4.0, Windows 2000 provides memory 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, outright 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 elaborate memory protection scheme to segregate the memory used for the kernel and applications, and a Storage Management Services module to provide a highly elastic backup and restore facility. Backups can live 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 hard confine to the number of servers you can configure in a cluster. Red Hat Linux likewise provides software RAID back through command line tools, has memory 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 elevated level of fault-tolerance. Currently, Non-Stop Clustering supports six servers in a cluster. UnixWare provides software RAID back that is managed using SCO's On-Line Data Manager feature. outright the touchstone RAID levels are supported. Computer Associates' bundled ArcServeIT 6.6 provides backup and restore capabilities. UnixWare has memory protection capabilities.Documentation
Because their testing was conducted before Windows 2000's general 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 live much easier to use if it gave more than a yoke of sentences at a time for a particular aid topic.
NetWare 5 comes with two manuals: a detailed manual for installing and configuring the NOS with marvelous explanations of concepts and features along with an overview of how to configure them, and a miniature 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 usher and a reference manual - outright of which are simple 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 marvelous job of reflecting this painful experience. The getting started usher 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 simple to follow.Wrapping up
The bottom line is that these NOSes tender a wide ambit of characteristics and provide enterprise customers with a grandiose deal of preference regarding how each can live used in any given corporate network.
If you want a good, general purpose NOS that can deliver enterprise-class services with outright the bells and whistles imaginable, then Windows 2000 is the strongest contender. However, for elevated performance, enterprise file and print services, their tests display that Novell leads the pack. If you're willing to pay a higher charge for scalability and reliability, SCO UnixWare would live a safe bet. But if you need an inexpensive alternative that will give you bare-bones network services with decent performance, Red Hat Linux can certainly apt the bill.
The preference is yours.

ActiveBatch Gets Blackberry Functionality
Administrators fill long been able to receive pages when servers depart down, but now they can restart servers with their pagers. Advanced Systems Concepts Inc. has added the Blackberry line of pagers to its list of clients for the ActiveBatch Job Scheduling and Management System.
The ActiveBatch Wireless Client is a module for the management software that enables administrators to monitor systems and initiate processes from the Blackberry. ActiveBatch Job Scheduling and Management System allows users to set up calendars to initiate processes such as backups or printing, or initiate processes from remote clients.
Ben Rosenberg, CEO of Advanced Systems, says the company chose to back the Blackberry first since it was the handheld best suited for round-the-clock monitoring. "The battery life is three weeks, and it’s always on," he says. Advanced Systems supports both the pager-sized and PDA-sized Blackberries.
If a system sends out an SNMP signal, administrators can configure the system to transmit an e-mail to a Blackberry, alerting the administrator. The e-mail gives the administrator the option to initiate processes, such as rebooting a server, through the Blackberry. "With the Blackberry, e-mails are always actionable by you," Rosenberg says.
Rosenberg sees two advantages to system management through wireless devices. First, it obviates the need to give instructions over the phone to a less experienced operator. Second, high-level administrators who travel can preserve an eye on the system. "If you’re on the road, you’re able to know if something is wrong," he says. With both advantages, administrators will live better able to guarantee uptime, with less repercussion on their lives.
In addition to the three levels of encryption standards on Blackberry devices, ActiveBatch provides additional security features, such as a password login to the system. This keeps random users, including thieves, from wreaking havoc on corporate systems. "Use of ActiveBatch is always secure," Rosenberg says.
ActiveBatch can manage Windows, OpenVMS and Unix-based systems with an agent on each server. The agent sends information to a central Windows console. The software integrates with the Windows Management Instrument, which likewise serves as a SNMP provider. ActiveBatch provides three plug-ins for remote clients: e-mail, browser and now the Blackberry.
Rosenberg says Advanced Systems is working to bring ActiveBatch to PocketPC handhelds. He says that although users can already use them with the browser-based system, the company will adapt the system to better meet the needs and limitations of the PocketPC platform.

Vendors do Linux Itanium-Ready
With Intel Corp.’s May release of its 64-bit Itanium processor, Linux vendors are lining up to back the unusual architecture. Red Hat Inc., TurboLinux Inc., SuSE AG and Caldera International Inc. outright formally released distributions for Itanium.
To coincide with the announcement, TurboLinux released its Operating System 7 for the Itanium processor. "It’s production-ready," says Thrane Jensen, product manager for Itanium. However, Jensen admits that many users will use early Itanium machines for testing and development, rather than using them in production environments yet.
Bill Claybrook, research director for Linux and open source at the Aberdeen Group, confirms that "most people are waiting for McKinley." He believes that users will wait for Intel to release McKinley—its second-generation IA-64 processor—before they integrate IA-64 into their environments. "They’re being a limited bit leery of it [in] a production environment," he says. Jensen says TurboLinux is working on its McKinley version of Linux already.
Jensen says that porting Linux to the IA-64 processor had its challenges. The 64-bit nature of the processor created challenging issues for stirring applications over to the unusual chip. "Dependencies on 32-bit create problems," he says. Some applications addressed specific 32-bit features that did not exist in Itanium. For the most part, applications could live recompiled for the chip. "In general, it’s along the same code line," he says, "but the kernel has [alot of] different stuff."
In addition to the core operating system, Jensen says many favorite Linux applications are likewise ready for prime time. Apache and other commonly used applications are production-ready, but "ISVs are going to live doing more application development," he says.
Red Hat released its Red Hat Linux 7.1 for the Itanium processor in mid-June. Using the 2.4 kernel, Red Hat positions the unusual release as a platform for testing 64-bit applications ported from 32-bit and RISC machines. The distribution is likewise suited to enterprise server needs; it runs on up to eight processors and offers unusual configuration tools for BIND, Apache and printing.
At the same time, Linux vendor SuSE released an Itanium-specific distribution. SuSE Linux 7.2 for IA-64 uses six CD-ROMs to carry over 1,500 applications for the emerging platform. relish Red Hat, the company bills the package as a solution for evaluating and deploying Itanium-based servers.
Although a preview version was already available from the Caldera FTP site at ftp.caldera.com/ia64, Caldera released two unusual versions in May, accompanied by a public announcement. The final production version of OpenLinux Server 64 should live available late in the third quarter.
Biff Traber, senior vice president and general manager of the server traffic line at Caldera, says Caldera has limited to lose by waiting to release a production version. Customers will eye to the distribution for evaluation purposes, so a beta release meets their needs. "It’s a combination of testing, evolution and prototyping," he says.
The Trillian project, which initiated evolution of a Linux kernel for the Itanium processor, first released a kernel in February 2000, predating Itanium’s general availability by over a year. Intel was aggressive in getting prototype chips to developers to ensure a market providing hardware, remote servers and emulators to enable open source developers to fill Linux ready for the release date.
The project later changed its name to the more formal-sounding IA-64 Linux Project and worked to further enhance the evolution of Linux on Itanium. Itanium is not the first 64-bit platform to elope Linux—there were already flavors of Linux for Sun Microsystems Inc.’s Sparc processor and Compaq Computer Corp.’s Alpha. In addition to the distributors, the IA-64 Linux Project likewise boasted hardware vendors, Hewlett-Packard Co., IBM Corp., Silicon Graphics Inc., VA Linux Systems Inc. and NEC Corp., as well as Intel and Swiss research laboratory CERN.
