You cannot control the M.2 SATA SSDs in the server with a HW RAID controller.
Note
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
with embedded SATA RAID, it is enabled at the factory.
• (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
be set to
LSI SW RAID
mode.
Embedded SATA RAID Controller Considerations
Note the following considerations:
• The default setting for this embedded controller hub is SATA RAID 0, 1, and 10 support for up to eight
front-loading SATA drives, and up to two internal M.2 SATA drives. The hub is divided into two SATA
controllers that have different functions. See
Embedded SATA RAID: Two SATA Controllers, on page
• When you order the server with this embedded controller, the controller is enabled in the BIOS. Instructions
for enabling the controller are included for the case in which a server is reset. See
For the Embedded Controllers , on page 98
• You cannot downgrade from using a hardware RAID controller card to using the software RAID embedded
controller (see
RAID Controller Migration, on page 93
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.
Caution
• The required drivers for this controller are already installed and ready to use with the LSI SWRAID
Configuration Utility.
