up to three DIMMs each.
The x240 includes 8 GB of memory (2x 4 GB DIMMs) running at either 1600 MHz or 1333
MHz depending on model. Some models include an Embedded 10Gb Virtual Fabric Ethernet
LAN-on-motherboard (LOM) controller as standard, this embedded controller precludes the
use of an I/O adapter in I/O connector 1. Model numbers in the form x2x (for example
8737-L2x) include an Embedded 10Gb Virtual Fabric Ethernet LAN-on-motherboard (LOM)
controller as standard. Model numbers in the form x1x (for example 8737-A1x) do not include
this embedded controller.

The x240 with the Intel Xeon E5-2600 series processors can support up to 768 GB of
memory in total when using 32 GB LRDIMMs and with both processors installed. The x240
uses Double Data Rate-3 (DDR-3) low-profile (LP) DIMMs. The x240 supports three types of
DIMM memory:

Registered DIMM (RDIMM) modules

Unbuffered DIMM (UDIMM) modules

Load-reduced (LRDIMM) modules
The mixing of these different memory DIMM types is not supported.
The x240 compute node features an onboard LSI 2004 SAS controller with two small form
factor (SFF) hot-swap drive bays that are accessible from the front of the compute node. The
onboard LSI SAS2004 controller provides RAID 0, RAID 1 or RAID 10 capability and supports
up to two SFF hot-swap SAS or SATA HDDs or two SFF hot-swap solid state drives.

the internal HDD interface.

Embedded 10Gb Virtual Fabric Adapter
Some models of the x240 include an Embedded 10Gb Virtual Fabric Adapter (VFA, also
known as LAN on Motherboard or LOM) built into the system board. Each of these models
that includes the embedded 10Gb VFA also has the Compute Node Fabric Connector
installed in I/O connector 1 (and physically screwed onto the system board) to provide
connectivity to the Enterprise Chassis midplane.

I/O expansion
The x240 has two PCIe 3.0 x16 I/O expansion connectors for attaching I/O adapter cards.
There is also another expansion connector designed for future expansion options. The I/O
expansion connectors are a very high-density 216 pin PCIe connector. By installing I/O
adapter cards it allows the x240 to connect with switch modules in the IBM Flex System
Enterprise Chassis.
