IBM Flex System x220 Compute Node 14
ServeRAID H1135
The x220 also supports an entry level hardware RAID solution with the addition of the ServeRAID H1135
Controller for IBM Flex System and BladeCenter. The H1135 is installed in a dedicated slot at the front of
the server (see Figure 3). When the H1135 adapter is installed, the C105 controller is disabled.
The H1135 has the following features:
Based on the LSI SAS2004 6 Gbps SAS 4-port controller

PCIe 2.0 x4 host interface

CIOv form factor (supported in the x220 and BladeCenter HS23E)

Support for SAS, SATA, and SSD drives

Support for RAID 0, RAID 1, and non-RAID

6 Gbps throughput per port

Support for up to two volumes

Fixed stripe size of 64 KB

Native driver support in Windows, Linux, and VMware

S.M.A.R.T. support

Support for MegaRAID Storage Manager management software

ServeRAID M5115
The ServeRAID M5115 SAS/SATA Controller (90Y4390) is 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 memory
when attached to an optional supercapacitor. The M5115 attaches to the I/O adapter 1 connector and can
be attached even if the Fabric Connector is installed (used to route the Embedded Gb Ethernet to chassis
bays 1 and 2). The ServeRAID M5115 cannot be installed if an adapter is installed in I/O adapter slot 1.
When the M5115 adapter is installed, the C105 controller is disabled.
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

We describe these configurations in the following section.
The ServeRAID M5115 controller has the following specifications:
Eight internal 6 Gbps SAS/SATA ports.

PCI Express 3.0 x8 host interface.

6 Gbps throughput per port.

800 MHz dual-core IBM PowerPC® processor with an LSI SAS2208 6 Gbps RAID on Chip (ROC)

controller.
Support for RAID levels 0, 1, 10, 5, 50 standard; support for RAID 6 and 60 with optional upgrade

using 90Y4411.
Optional onboard 1 GB data cache (DDR3 running at 1333 MHz) with optional flash backup

(MegaRAID CacheVault technology) as part of the Enablement Kit 90Y4342.
Support for SAS and SATA HDDs and SSDs.

Support for intermixing SAS and SATA HDDs and SSDs. Mixing different types of drives in the same

array (drive group) is not recommended.
Support for self-encrypting drives (SEDs) with MegaRAID SafeStore.
