##### RAID Support Using SIA

SIA currently only supports RAID configuration on systems that include an integrated LSI 1068E controller, or optional LSI SAS-2 controllers (926x, 9280). If your system does not include any of these controllers, the RAID configuration task in SIA will not be available.

SIA can only be used to configure RAID 1 (mirroring) on available SAS or SATA disk drives. You cannot mix SAS and SATA drives in a RAID volume. If you plan on using SAS and SATA disks, they must reside in separate RAID volumes.

The types of RAID 1 volumes that can be configured using SIA depends on the controller type you are using.

- For LSI 1068E controllers you can configure:

  - RAID IM — An Integrated Mirroring volume that uses two mirrored disks. Up to two RAID volumes are supported. Each volume must have 2 disks. Hot spares cannot be configured using SIA. To configure hot spares, use the disk controller's BIOS configuration tool available during system boot.

  - RAID IME — An Integrated Mirroring Enhanced volume that can have three to ten striped, mirrored disks. Up to two RAID volumes can be configured for the system. The two volumes can have up to 12 disks. Hot spares cannot be configured using SIA. To configure hot spares, use the disk controller's BIOS configuration tool available during system boot.

- For LSI MegaRAID (926x, 9280) SAS-2 controllers you can configure:

  - RAID 1 — A mirrored volume that uses two mirrored disks. Up to 32 RAID volumes are supported. Each volume must have 2 disks. Hot spares cannot be configured using SIA. To configure hot spares, use the disk controller's BIOS configuration tool available during system boot.
