Technical Specifications
Your system is a high-speed, full-featured server that offers significant service and upgrade features. This section describes the major features of the system,
including those that simplify servicing. It also provides information about other documents you may need when setting up your system.
The hard drive that boots your operating system has a utility partition containing complete diagnostics for your system. Also, a separate CD is provided that
includes diagnostics software that you can download to a set of diskettes.
System Features
One or two Intel® Xeon™ microprocessors with an internal operating speed of at least 1.8 GHz, a 512 KB cache, and a front-side (external) bus speed
l
of 400 MHz.
The microprocessors in your system provide NetBurst microarchitecture and Hyper-Threading Technology to significantly increase microprocessor
performance. Hyper-Threading allows one physical microprocessor to appear as two logical processors to the operating system and application
programs. Hyper-Threading also allows each microprocessor to simultaneously execute multiple tasks using shared hardware resources.
These new technology features in the microprocessor provide the following for multithreaded tasks:
Enhanced system performance
¡
Improved reaction and response time for the system
¡
Increased number of users that a system can support
¡
Increased number of transactions that can be executed simultaneously by the system
¡
You can find more information about Hyper-Threading at developer.intel.com.
SMP, which is available on systems with two Xeon microprocessors. SMP greatly improves overall system performance by dividing microprocessor
l
operations between independent microprocessors. To take advantage of this feature, you must use an operating system that supports multiprocessing.
NOTE:
If you decide to upgrade your system by installing an additional microprocessor, you must order the microprocessor upgrade kits from the
company where you purchased your system. Not all versions of the Intel Xeon MP microprocessor will work properly as additional microprocessors.
The upgrade kit contains the correct version of the microprocessor as well as the instructions for performing the upgrade. All microprocessors must
have the same internal operating frequency and cache size.
A minimum of 256 MB of system memory, upgradable to a maximum of 6 GB by installing identical pairs of DDR SDRAM memory modules in the six memory
l
module sockets on the system board.
Support for up to five 1-inch, internal Ultra3 SCSI hard drives (with hot-plug capacity when using the optional ROMB card).
l
A single, 1.44-MB, 3.5-inch diskette drive.
l
An IDE CD or DVD drive.
l
Up to two hot-pluggable, 500-W AC or DC power supplies in a 1 + 1 redundant configuration.
l
Hot-pluggable system cooling fans and two additional fans integrated in the power supplies.
l
An intrusion switch that signals the appropriate systems management software if the bezel is removed.
l
System Board Features
Three 64-bit PCI/PCI-X slots located on the riser card (two slots on bus 1 and one slot on bus 2). Slots accept full-length cards designed for PCI-X up to
l
133 MHz.
An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory
l
(nonupgradable). Maximum resolution is 1600 x 1200 x 16.7 million colors (noninterlaced).
An integrated, dual-channel Ultra3 SCSI host adapter. The internal channel supports up to five SCSI hard drives on a 1 x 5 or 2/3 split SCSI backplane
l
and provides internal RAID support. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard drives,
greatly simplifying drive installation.
Memory spare bank feature, which provides your system with failover to a previously reserved row of memory if one row of memory fails.
l
Optional ROMB through an integrated subsystem that incorporates a 128 MB cache memory module, a RAID battery, and a RAID key.
l
Two integrated 10/100/1000 NICs, which provide an Ethernet interface.
l
Embedded systems management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The systems
l
management circuitry works in conjunction with your systems management software.
