1.3.1 Supported BladeCenter chassis
The PS703 and PS704 blades are supported in the IBM BladeCenter chassis as listed in
Table 1-2.
Table 1-2 The blade servers supported in each BladeCenter chassis
IBM BladeCenter H delivers high performance, extreme reliability, and ultimate flexibility for
the most demanding IT environments. See “BladeCenter H” on this page.
IBM BladeCenter HT models are designed for high-performance flexible telecommunications
environments by supporting high-speed networking technologies (such as 10G Ethernet).
They provide a robust platform for NGNs. See “BladeCenter HT” on page 7.
IBM BladeCenter S combines the power of blade servers with integrated storage, all in an
easy-to-use package designed specifically for the office and distributed enterprise
environments. See “BladeCenter S” on page 10.
BladeCenter H
IBM BladeCenter H delivers high performance, extreme reliability, and ultimate flexibility to
even the most demanding IT environments. In 9 U of rack space, the BladeCenter H chassis
can contain up to 14 blade servers, 10 switch modules, and four power supplies to provide the
necessary I/O network switching, power, cooling, and control panel information to support the
individual servers.
The chassis supports up to four traditional fabrics using networking switches, storage
switches, or pass-through devices. The chassis also supports up to four high-speed fabrics
for support of protocols such as 4X InfiniBand or 10 Gigabit Ethernet. The built-in media tray
includes light path diagnostics, two front USB 2.0 inputs, and an optical drive.

Note: The number of blade servers that can be installed into chassis is dependent on the
power supply configuration, power supply input (110V/208V BladeCenter S only) and
power domain configuration options. See 1.3.2, “Number of PS703 and PS704 blades in a
chassis” on page 12 for more information.
