Overview
This server is a highly reliable, high-powered, highly available, high-capacity
multiprocessing system based on the Intel
performer and offers the latest technology. The server system is conveniently housed
and available as a tower-based system (see Figure 1-1).
The combination of superior computing performance, high memory capacity, and
integrated I/O provides a high performance environment for the many sophisticated
applications available to network servers. The server system is designed for use in
applications where advanced technology, high performance, and high levels of
reliability and compatibility are expected at all times.
This server system is designed for minimum downtime. To this end, the server includes
or has the option to include the following:
!
A chassis that supports up to three self-contained power supplies (two are standard
power supplies). An additional power supply can be added to provide redundant
power (i.e., the system will continue to operate with a single power supply failure).
If optional power system redundancy is installed, the power supply units are then
hot-swappable and can be easily installed or removed from the back of the chassis
without turning the system power off.
!
Four fan modules that can be easily installed or removed from the side of the system.
The fan modules contain a total of six fans for effective cooling. An additional fan
cools the disk drive bay and each power supply contains a fan.
!
Cooling system redundancy where the system will continue to operate in the event of
a fan failure or having cabinet temperatures approaching the threshold limit, the
redundant fans will switch to maximum operating speed.
!
Up to ten SCSI drive bays accessible from the front of the cabinet.
