Overview

This server is well suited for Symmetric Multiprocessing (SMP) and Enterprise class network server environments and is a highly reliable, high-powered, fault-tolerant, high-capacity multiprocessing system based on the Intel Xeon® processor family. It is a fully redundant system with on-line serviceability and hot plug replacement of all major subsystems and a solid performer offering the latest technology. The server is conveniently housed and available as a tower-based system (see Figure 1-1) or as a rack-mount system (see Figure 1-2) in a relatively small form factor (fits into a standard EIA 19-inch rack assembly.)

The combination of mirrored computing performance, memory capacity, and integrated I/O provides a high performance environment for many applications including network servers. The server is designed for use in applications where fault-tolerant, advanced technology, high performance, and high levels of reliability and compatibility are expected.

1-2 System Overview

Figure 1-1. Tower-Based System

Figure 1-2. Rack-Mount System

This server is designed for full redundancy and hot plug replacement of all major subsystems. The system modules that can be replaced are identified as Customer Replaceable Units (CRUs) of which most are redundant and hot pluggable. To this end, the server includes or has the option to include the following:

! SCSI hard disk drive bays accessible from the front of the chassis. ! Hot-swap SCSI disk drive backplane; a failed drive can be removed and replaced

with a new drive without system power being turned off.

! High degree of SCSI disk fault tolerance and advanced disk array management

features.

! Video Graphics Array (VGA) controller with 2 MB of video memory (occupies one

PCI slot per PCI module).

! SCSI disk adapter providing Ultra 160 SCSI interface for the hot swap hard disk

drives.

! Embedded single channel enhanced IDE adapter providing interface for a peripheral

device (CD-ROM drive).

! Integrated Network Interface Controller (NIC), supporting 10Base-T/100Base-

TX/1000Base-T network systems.

! Storage module that holds up to six hot-swap SCSI hard disk drives (three logical

disks).

! SCSI backpanel is Ultra2 capable. ! Integrated dual Universal Serial Bus (USB) ports that include support for the

keyboard, mouse, and a USB floppy diskette drive.

! Hardware monitors (temperature, fans, and voltage) and software monitors to

indicate failures.

! Easy access to all parts for service.

System Overview 1-3

As application requirements increase, you can expand your server with additional processors, additional memory, add-in boards and peripheral devices.

Your server features the following major components:

! Up to two high-performance Xeon 2.4GB processors in each CPU module. ! Up to 3 GB of Synchronous Dynamic Random-Access (SDRAM) system memory in

each CPU module.

! Three PCI expansion slots, which support one 32-bit/33Mhz and two 64-bit/33Mhz

PCI adapter cards in each PCI module. One of the PCI expansion slots in each PCI module contains a graphics board.

Fault-Tolerant Hardware

The hardware architecture of the system provides fault tolerance transparency. If a hardware component fails, the application program continues processing and is never aware that a failure occurred.

To provide system redundancy this system uses dual hardware technology. That means that all major components are mirrored within a single hardware chassis. There are two CPU modules and each CPU module is operating in lockstep (performing the same instructions at the same time) with the other as a single system. Thus, if a failure occurs in one CPU module the other CPU module will continue to operate with no interruption, no loss of data, and system performance is not affected. Note that the PCI module, PCI adapters, and power supplies are also paired for system redundancy.
