Ibm Flex System X220 Compute Node - IBM V7000 Introduction And Implementation Manual

1.4.3 IBM Flex System x220 Compute Node

The IBM Flex System x220 Compute Node, machine type 7906, is the next generation
cost-optimized compute node designed for less demanding workloads and low-density
virtualization. The x220 is efficient and equipped with flexible configuration options and
advanced management to run a broad range of workloads. It is a high-availability, scalable
compute node optimized to support the next-generation microprocessor technology. With a
balance between cost and system features, the x220 is an ideal platform for general business
workloads. This section describes the key features of the server.

The IBM Flex System x220 Compute Node features the Intel Xeon E5-2400 series
processors. The Xeon E5-2400 series processor has models with either four, six, or eight
cores per processor with up to 16 threads per socket. The processors have up to 20 MB of
shared L3 cache, Hyper-Threading, Turbo Boost Technology 2.0 (depending on processor
model), one QuickPath Interconnect (QPI) link that runs at up to 8 GT/s, one integrated
memory controller, and three memory channels supporting up to two DIMMs each.
The x220 also supports an Intel Pentium 1403 or 1407 dual-core processor for entry-level
server applications. Only one Pentium processor is supported in the x220. CPU socket 2 must
be left unused and only six DIMM socks are available.
The x220 supports Low Profile (LP) DDR3 memory registered DIMMs (RDIMMs) and
unbuffered DIMMs (UDIMMs). The server supports up to six DIMMs when one processor is
installed and up to 12 DIMMs when two processors are installed. Each processor has three
memory channels, and there are two DIMMs per channel.
The x220 server has two 2.5-inch hot-swap drive bays accessible from the front of the blade
server as shown in Figure 1-10. The server optionally supports three internal disk controllers
allowing a greater number of internal drives up to a maximum of eight with the ServeRAID
M5115 controller and also supports 1.8-inch solid-state drives.
