Server Chassis (enclosure)

This section describes server chassis.

Overview

The 6U server chassis can contain up to eight server blades and four switch
modules. Compared with a 1U server chassis with an external rack mount
network switch and FC switch, the 6U server chassis consumes less space,
requires fewer cables and weighs less. The connection between each module
is through the internal backplane in the server chassis. Thus a complicated
cable connection is unnecessary. When you need to add a server blade to a
chassis, you can add the server blade just by inserting it in a spare slot. The
system is designed to consolidate existing rack-mount server systems, for
server consolidation and for operation in a data center. Switch modules can
be selected according to your needs. Management modules, switch modules,
power supply modules and fan modules can each be provided in a redundant
configuration such that the system can continue to operate even if one of the
modules fails. Power supplies required for server blades are installed in a
server chassis. Thus stable electric power can be supplied in a very small
space. The external interface is shared between server blades using a
switching function to conserve space. The server chassis for CB 500 offers the
following key features:
• Up to 8 multi-core 2-socket processor half-wide blades
• Up to 4 multi-core 4-socket processor full-wide blades
• Up to 4 high-throughput flexible IO switch modules
• High density laminated substrate backplane for future IO interfaces
• 80 PLUS Platinum power supply and Power Capping with Energy reduction
technologies
• High levels of reliability/availability/maintainability (RAS) including
multiple redundant configurations and customer serviceability
