Server Blade
This section describes server blades.
Overview
The CB 500 server blade offers the following key features:
• High-performance Intel multi-core processor with QPI technology for
high-throughput and low-latency.
• High reliability functions through the processor, memory and HDD
reliability/availability/maintainability features, such as memory scrubbing
(self-error-correcting), memory mirroring function (memory duplication),
and integrated Hardware RAID 1.
• High density, high performance optimized for enterprise data center,
virtualization, high-speed computation, and flexible IO capability.
A server blade contains processors, memory, HDDs, and other components,
and is available in either of two form factors: the "half-wide" blade; "full-
wide" blade. There are also two types of half-wide blades, the "storage
expansion" blade for additional HDDs and the "PCI expansion" blade for
additional PCI Express cards.
