Cisco UCS C240 M5 Service Manual

Embbeded SATA RAID Requirements
The embedded SATA RAID controller requires the following items:
•
For control of front-loading SATA drives: SFF, 8-drives server version UCSC-C240-M5S (only). Other
versions of the server do not support control of front-loading drives with this embedded controller.
•
For control of front-loading SATA drives: Interposer card UCSC-SATAIN-240M5 installed in the
dedicated storage controller socket.
•
For control of front-loading SATA drives: 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 and a DVD drive is present on the pSATA controller,
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 SFF, 8-drives version of the server (UCSC-C240-M5S) can use the embedded SATA controller to
control up to eight front-loading, SATA-only drives, and up to two internal M.2 SATA drives. Control
of the two internal M.2 SATA drives is supported in all versions of the server; control of front-loading
drives is not supported in other versions of the server.
•
The default setting for this embedded controller hub is SATA RAID 0, 1, and 10 support for up to eight
SATA drives. The hub is divided into two SATA controllers that have different functions. See Embedded
SATA RAID: Two SATA Controllers, on page 139.
•
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 to defaults.
See Enabling SATA Mode For the Embedded Controllers , on page 139.
•
You cannot downgrade from using a hardware RAID controller card for front-loading drive control to
using the software RAID embedded controller for front-loading drive control (see RAID Controller
Migration, on page 133).
Data migration from software RAID (embedded RAID) to hardware RAID (a controller
card) for front-loading drives 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
front-loading drives, or when there are no drives in the server.
