Appendix C RAID Controller Considerations

Embedded SATA RAID Controller

Note VMware ESX/ESXi or any other virtualized environments are not supported for use with the embedded

MegaRAID controller. Hypervisors such as Hyper-V, Xen, or KVM are also not supported for use with

the embedded MegaRAID controller.

This server includes an embedded MegaRAID controller hub that can control up to eight SATA-only

front-facing drives (SFF 8-drive server only). It can also control up to two internal boot SSDs (SFF

24-drive and LFF 12-drive servers only).

This section contains the following topics:

Embedded SATA RAID Controller Requirements For Front-Facing Drive Control

The embedded SATA RAID controller hub requires the following items:

• For front-facing drive control—The SFF, 8-drive version of the server.

The embedded RAID option is available for front-facing drive control only with the SFF 8-drive,

direct-connect backplane.

• A SATA interposer board and Y-cable (bundled as UCSC-IP-PCH-C240M4=).

This interposer board plugs into the motherboard and provides cable connectors.

• (Optional) A SATA RAID 5 key module.

This optional module can be installed to a motherboard header to add SATA RAID 5 support for

front-facing drives.

• The embedded SATA RAID controller must be enabled in the server BIOS.

• (Optional) LSI MegaSR drivers for Windows or Linux.

Note The embedded SATA RAID controller can also manage internal SSD boot drives in a RAID 1 array. For

that case, the requirement is either the LFF 12-drive or the SFF 24-drive version of the server. Only the

LFF 12-drive and the SFF 24-drive versions of the server support internal boot SSDs. No cabling is

required for managing the internal SSD boot drives.
