Storage Controller Considerations
Note
You cannot control the M.2 SATA SSDs in the server with a HW RAID controller.
Embbeded SATA RAID Requirements
The embedded SATA RAID controller requires the following items:
• Interposer card UCSC-SATAIN-220M5. This must be installed in internal mRAID riser 3.
• The SAS/SATA cables that are preinstalled in the chassis.
• Primary controller: SATA drives only (up to eight, in front drive bays 1–8).
• Secondary controller: M.2 mini-storage module with two SATA M.2 SSDs.
• The embedded SATA RAID controllers must be enabled in the server BIOS. If you ordered the server
• (Optional) LSI MegaSR drivers for Windows or Linux.
• The software RAID controller requires UEFI boot mode; Legacy boot mode is not supported.
• If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must

• The default setting for this embedded controller hub is SATA RAID 0, 1, and 10 support for up to eight
• When you order the server with this embedded controller, the controller is enabled in the BIOS. Instructions
• You cannot downgrade from using a hardware RAID controller card to using the software RAID embedded

Caution
Data migration from software RAID (embedded RAID) to hardware RAID (a
controller card) is not supported and could result in data loss. Migrations from
software RAID to hardware RAID are supported only before there is data on the
drives, or when there are no drives in the server.
