Dual Pentium 100s Come Out with Both Barrels
Blazin'
This thing is fast! And the greatest feature of a really fast machine is that when something isn't working, you know it instantly! But before I get into the few problems this machine has, let's look at its features and capabilities.
The Proliant Server 4500 is Compaq's top-end platform for server applications. The test unit came equipped with enough goodies to satiate even the greediest system
administrator: two 100-MHz Pentium chips, 160MB of RAM, 10GB of disk--RAID 5
(with parity) so there's only 8GB of effective storage space--a quad-speed
CD-ROM drive, and dual SCSI-2 controllers--one 32-bit fast and wide SCSI
controller and one SMART SCSI Array Controller. These are the upgrades that make
this system so fast. A dual-processor architecture is great, but without the
memory (and the disk) to back it up, system overhead eats up any computing-speed
advantages you would otherwise see. Having two controllers allows you to break
system operations away from software and data operations, so that the same drive
isn't servicing the operating system--for virtual memory, swapping space,
etc.--while it's trying to run applications.
Out of the box, the Proliant Server 4500 is impressive: Its full-tower
chassis can house up to four hot-pluggable full-height hard drives and has eight
EISA slots, two of which are already taken by the SCSI controllers. The 4500 has
a standard HD floppy and a CD-ROM drive (plus one unused 51/4" drive bay),
as well as the usual array of expansion connectors (SCSI, serial, parallel, SVGA
graphics, PS/2 keyboard and mouse, and 10BaseT connection). Where the 4500
really shines, however, is in upgradability: four processor slots and up to 1GB
of Error-Correcting Circuitry (ECC) RAM. It will take most users quite a while
to outgrow this machine.
I also had the SMART SCSI Array Controller and the auxiliary storage
expansion unit jammed with five 2.1GB drives. This setup is most impressive; it
took perhaps 15 seconds to format an 8GB NT File System (NTFS) partition
spanning all drives.
The few problems I had with this system can be summarized in one statement:
Whatever you do, don't try to manually configure this beast on your own! If you
do, you're in for a long trip through computer never-never-land. Compaq supplies
a SmartStart kit with these systems, from which--with the appropriate code
keys--you can install any of a variety of operating systems (among them, SCO
UNIX, DOS, and Windows NT), databases (SQL Server 4.21, Oracle7, etc.), and
other server-management packages (Cheyenne's ARCServe, Compaq's proprietary
administration software, etc.). However, I didn't have the SmartStart kit to
begin with, so I tried to do a standard install of Windows NT Server 3.51. This
process introduced me to the intricacies of Compaq's proprietary Hardware
Abstraction Layer (HAL), as in, "There is one." Thus, you must
run Compaq's own flavor of Windows NT to make it work. Heaven help you if
you lose your source disk!
Once I discovered this fact and received the appropriate package from
Compaq, SmartStart automated the entire installation and configuration process.
That's both good and bad. It's good because it steps you through everything you
need to do; and it's bad because it steps you through everything you need to do.
If you are missing one piece of information, such as a network address,
you must abort the configuration and start again when you have all the
pieces. (And be sure that you have the activation keys ready for any software
you want to install, especially the operating system). This process is quite
cumbersome: You must enter everything in its entirety before you can continue,
rather than being able to skip parts and fill them in later. To its credit,
however, Compaq reports that it is improving the SmartStart kit to make it even
easier to use--improvements that will address some of these problems.
When all is said and done, once the Compaq Proliant Server 4500 was up and
running, it proved to be one incredible piece of hardware. It's fast, stable,
and doesn't appear to suffer from any major compatibility problems. In fact,
this is one machine that Windows NT Magazine Lab would love to
keep around as a test platform.
