IBM Flex System x240 Compute Node (E5-2600) 13
Internal storage
The x240 server has two 2.5-inch hot-swap drive bays accessible from the front of the blade server
(Figure 2). These bays connect to the integrated LSI SAS2004 6 Gbps SAS/SATA RAID-on-Chip (ROC)
controller.
The integrated LSI SAS2004 ROC has the following features:
Four-port LSI SAS2004 controller with 6 Gbps throughput per port

PCIe x4 Gen 2 host interface

Two SAS ports routed internally to the two hot-swap drive bays

Supports RAID-0, RAID-1 and RAID-1E

The x240 also supports up to eight 1.8-inch drives with the addition of the ServeRAID M5115 controller
and additional SSD tray hardware. These are described in the next section.
Supported drives are listed in the Internal drive options section.
ServeRAID M5115 SAS/SATA controller
The x240 supports up to eight 1.8-inch solid-state drives combined with a ServeRAID M5115 SAS/SATA
controller (90Y4390). The M5115 attaches to the I/O adapter 1 connector and can be attached even if the
Compute Node Fabric Connector is installed (used to route the Embedded 10Gb Virtual Fabric Adapter to
bays 1 and 2, as discussed in "I/O expansion options"). The ServeRAID M5115 cannot be installed if an
adapter is installed in I/O adapter slot 1.
The ServeRAID M5115 supports combinations of 2.5-inch drives and 1.8-inch solid state drives:
Up to two 2.5-inch drives only

Up to four 1.8-inch drives only

Up to two 2.5-inch drives, plus up to four 1.8-inch solid state drives

Up to eight 1.8-inch solid state drives

The ServeRAID M5115 SAS/SATA Controller (90Y4390) provides an advanced RAID controller
supporting RAID 0, 1, 10, 5, 50, and optional 6 and 60. It includes 1 GB of cache, which can be backed up
to Flash when attached to the supercapacitor included with the optional ServeRAID M5100 Series
Enablement Kit (90Y4342).
At least one hardware kit is required with the ServeRAID M5115 controller, and there are three hardware
kits that are supported that enable specific drive support.
