IBM Flex System x440 Compute Node 14
Support for 1.8-inch SSDs
In addition, the x440 supports up to eight 1.8-inch SSDs 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 described 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 SSDs:
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 SSDs


The ServeRAID M5115 SAS/SATA Controller (90Y4390) provides an advanced RAID controller
supporting RAID 0, 1, 10, 5, 50, and, optionally, 6 and 60. It includes 1 GB of cache, which can be backed
up to flash memory when attached to the supercapacitor included with the optional ServeRAID M5100
Series Enablement Kit (46C9030).
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, as listed in the following table.
