1-2 System Overview
Overview
The server is a modular, multiprocessing server based on the Intel

Pentium®
II Xeon chip set. The chip set incorporates a modular scaleable architecture that
integrates a 64-bit bus interface with three Peripheral Component Interconnect
(PCI) buses and an Industry Standard Architecture (ISA) bus. The architecture
supports Symmetrical Multiprocessing (SMP) and a variety of operating
systems. The chassis and system boards are designed to meet the needs of the
server marketplace.
The combination of computing performance, memory capacity, and integrated
I/O provides a high performance environment for many applications including
network servers and multi-user systems. The server is designed for use in
applications where downtime must be minimized. To this end, the server
includes or has the option to include the following.
„
Power system redundancy; in a system configured with redundant power
supplies, the system will continue to operate with a single power supply
failure.
„
Self-contained power supply units that can be easily installed or removed
from the back of the chassis.
„
Hot-swap Ultra2 SCSI-3 hard drive bays accessible from the front of the
chassis; a failed drive can be removed, and a new drive installed without
system power being turned off.
„
High degree of SCSI hard disk fault tolerance and advanced disk array
management features through the use of RAID (Redundant Array of
Independent Disks) technology.
„
Hardware monitors (temperature and voltage) and software monitors to
indicate failures.
„
Easy access to all parts for service.
