Features of the CB 2500
To achieve high performance, the CB 2500 supports the maximum number of
memory modules defined by CPU architectures, and supports high-speed I/O
by using 10Gb Ethernet or 16Gb Fibre Channel. In addition, four hot-
pluggable PCI Express slots are supported and high reliability is achieved by
using multipath connections to connect with storage systems. Due to these
features, you can build a highly-available system that best suits your
business or goals. The following shows the hardware that makes up the CB
2500 system unit.
Hardware that makes up the CB 2500
• Server chassis
A server chassis is a frame chassis equipped with server blades and
various modules. A server chassis can be equipped with a maximum of 8
full-wide blades or a maximum of 14 half-wide blades. In addition, a
server chassis can be equipped with a maximum of 2 switch modules.
• Server blade
A server blade is a device containing a collection of server functionality.
Models such as full-wide and half-wide blades are available so that the
necessary number of servers can be installed for your operation.
• PCI expansion blade
A PCI expansion blade is a device that is used to expand I/O adapter
slots. PCI expansion blades have a maximum of six I/O adapter slots. One
PCI expansion blade is used in combination with one half-wide blade.
• Management module
A management module manages the entire system unit. You can use a
management module to monitor the operating statuses of server blades
and various modules, and to set their power control or network
information. By installing two management modules in the CB 2500 for
redundancy, you can enhance the fault tolerance of the system unit. In
addition, the management modules connect to external networks via
management LAN modules.
• Switch module
A switch module provides a network adapter and switch functionality to
the system unit. A switch module can be a DCB switch that consolidates
LANs and SANs. In the CB 2500, a maximum of two switch modules are
installed to secure the network bandwidth needed by the server blades.
• I/O board module
An I/O board module supports various PCI adapters and provides their
I/O interfaces. Supported PCI adapters include LAN adapters, fibre
channel adapters, and flash drive adapters.
• Power supply module
A power supply module supplies power to the system unit. A maximum of
6 power supply modules can be installed in the CB 2500 server chassis.
• Fan module
