Features of server blades
CB 2500 server blades support the following two types of performance
expansion to best match your business or goals: scale-up and scale-out. You
can use multiple server blades as one server by SMP connections to scale up
the server, and then use the server as a database server or application server
that requires high performance. In addition, multiple server blades can be
scaled out in parallel, and used as a Web server that requires high
throughput for a large number of accesses.
CPUs, memory, and HDDs are mounted on a server blade. In addition, In
addition, CNA (Converged Network Adapter) and mezzanine cards are also
mounted. Onboard CNA and mezzanine cards are connected with switch
modules via the backplane of a server chassis.
In addition, a PCI expansion blade can be used in combination with a half-
wide blade to expand I/O adapter slots. A PCI expansion blade is an option
for a half-wide blade.
The following shows the main features of CB 2500 server blades:
• Equipped with high-performance Intel multicore processors that use QPI
technology, which improves throughput and reduces delays.
• Provide high reliability by using CPUs and RAID controllers that have high
reliability, availability, and maintainability such as memory scrubbing (self
correction of errors), memory mirroring functionality (memory
duplication), and hardware RAID1.
• Support high density, high performance optimal for server data centers,
virtualization, high-speed computer processing, and flexible I/O
capability.
• By installing flash storage in a PCI expansion blade, you can configure a
high-speed storage system.
