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 SCSI 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.
