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.
- 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 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 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 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).
- A single, 1.44-MB, 3.5-inch diskette drive.
- An IDE CD or DVD drive.
- Up to two hot-pluggable, 500-W AC or DC power supplies in a 1 + 1 redundant configuration.
- Hot-pluggable system cooling fans and two additional fans integrated in the power supplies.
- An intrusion switch that signals the appropriate systems management software if the bezel is removed.
- 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 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 (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 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.
- Optional ROMB through an integrated subsystem that incorporates a 128 MB cache memory module, a RAID battery, and a RAID key.
- Two integrated 10/100/1000 NICs, which provide an Ethernet interface.
- Embedded systems management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The systems management circuitry works in conjunction with your systems management software.
- Back-panel connectors including video, keyboard, mouse, two serial, two USB, embedded remote access Ethernet, and two NICs.
- Front-panel connectors including video, keyboard, mouse, and USB.
For more information about specific features, see "Technical Specifications."
The following software is included with your system:
- A System Setup program for quickly viewing and changing system configuration information. For more information on this program, see "Using the System Setup Program."
- Enhanced security features, including a system password and a setup password, available through the System Setup program.
- System diagnostics for evaluating system components and devices. For information on using the system diagnostics, see "Running the System Diagnostics."
- Video drivers for displaying many application programs in high-resolution modes. For more information on drivers, see "Using the Dell OpenManage Server Assistant CD" in your User's Guide.
- SCSI device drivers that allow the operating system to communicate with devices attached to the integrated SCSI subsystem. For more information on drivers, see "Installing and Configuring SCSI Drivers" in your User's Guide.
- Systems management software and documentation.
- Optional solutions software for web hosting, caching, or load balancing. See your solutions software documentation for more information.
- Microsoft® Windows® 2000 Server and Advanced Server
- Windows NT® 4.0 Server, Enterprise Edition
- Red Hat Linux 7.x, or later
The system includes the following service features to make troubleshooting and repair easy and effective, in most cases without tools or service aids:
- System diagnostics are available on the utility partition, which checks for hardware problems (if the system can boot). The diagnostics can also be installed onto diskettes from the Dell OpenManage Server Assistant CD.
- Optional systems management hardware and software, which monitors temperatures and voltages throughout the system and notifies you if the system overheats, if a system cooling fan malfunctions, if a microprocessor overheats, or if a power supply or VRM fails. For information about the systems management option, see your systems management software documentation.
- The system simplifies removing and replacing components. You can replace microprocessors or memory modules without removing the system board. The SCSI backplane board and hard-drive carriers eliminate the extensive cabling and drive configuration usually required for a SCSI subsystem.
A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.
Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's AC power source voltage at a fairly constant level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power.
UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when AC power is unavailable or unusable. The battery is charged by the AC power while it is available so that once AC power is lost, the battery can provide power to the system for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.
UPS systems that provide only 5 minutes of battery power allow you to conduct shutdown of the system but are not intended to provide continued operation. Use surge protectors with all UPS systems, and ensure that the UPS systems are UL safety approved.
