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).

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.
