RAID Controller Considerations
This appendix provides RAID controller information, and it includes the following sections:
• How to Determine Which Controller Is in Your Server, page C-1
• How to Disable Quiet Boot For CIMC Firmware Earlier Than Release 1.2(1), page C-2
• How To Launch an Option ROM-Based Controller Utility, page C-2
• For More Information, page C-2
How to Determine Which Controller Is in Your Server
This server can be ordered or configured with a number of different RAID controllers:
• RAID 0, 1, 5, 6, 10, 50, and 60 support for up to 12 SAS or SATA drives, with the optional LSI
MegaRAID SAS 9260-8i RAID controller
Note You can configure a mixture of SAS and SATA drives when using an LSI MegaRAID card.
However, you cannot mix SAS and SATA drives within a volume. Two hot spares are supported
so that you can configure a global hot spare for each type (SAS or SATA), and then configure
your volumes to use their corresponding hot spare type (SAS or SATA).
There is a dedicated SAS riser slot for the RAID controller card in the chassis. There is also a mounting
point inside the chassis for the optional RAID battery backup unit that is available when using the LSI
MegaRAID SAS 9260-8i controller.
If you do not have a record of which option is used in your server, you can read the on-screen messages
that are displayed during system bootup
Information about the models of card installed are displayed as part of the verbose boot. You are also
prompted to press Ctrl-H to launch configuration utilities for those cards. For servers running CIMC
firmware earlier than release 1.2(1), see also
How to Disable Quiet Boot For CIMC Firmware Earlier
Than Release 1.2(1), page C-2.
