1.1.2 Power E880 server
The Power E880 (9119-MHE) server is a powerful POWER8-based system that scales up to
16 sockets. Each socket contains a single 8-core POWER8 processor. Thus, a
fully-configured Power E880 can scale up to 128 cores. In 2014 up to two system nodes per
server are supported or a maximum of 64-cores.
The Power E880 is a modular system that is built from a combination of the following four
building blocks:
System control unit
System node
PCIe Gen3 I/O expansion drawer
EXP24S SFF Gen2-bay drawer
The system control unit provides redundant system master clock and redundant system
master Flexible Service Processor (FSP) and support for the Operator Panel, the system
VPD, and the base DVD.
Each system node provides four processor sockets for POWER8 processors and 32 CDIMM
slots supporting a maximum of 8 memory features. Using the 512 GB memory features, the
system node can support a maximum of 4 TB of RAM. Thus a two-node Power E880 can
support up to 8 TB of memory. A four-node Power E880 can support up to 16 TB of RAM.
Each system node provides eight PCIe Gen3 x16 slots.
