Hardware RAID Support

The servers provide hardware RAID support through on-board SAS3 RAID controllers. Each controller enables you to create up to two logical disk volumes consisting of two or more redundant disk drives. The following table identifies the hardware RAID controllers built into each server.

Server
Controller Description
Supported RAID Levels
SPARC T8-1
One on-board SAS3 controller
0, 1, 1e, 10
SPARC T8-2
Two on-board SAS3 controllers
0, 1, 1e, 10
SPARC T8-4
Two on-board SAS3 controllers
0, 1, 1e, 10

Note -  RAID 1e and RAID 10 are functionally equivalent. RAID 1e requires an odd number of drives (minimum three). RAID 10 requires an even number of drives (minimum four).

You can use the RAID management utilities described here with the on-board SAS3 controllers provided in these servers.

FCode-Based RAID Utility

You can use FCode-based commands provided with the on-board controller to display targets and manage logical volumes on the server. You enter these commands at the OpenBoot ok prompt.

The examples of RAID shown in this document rely on the controller's FCode-based commands, unless otherwise specified.

raidconfig Commands

You can use the raidconfig commands contained in the Oracle Hardware Management Pack. Use the Oracle Server CLI Tools component to create and manage RAID volumes on the server. See the Oracle Server CLI Tools for Oracle Solaris 11.3 User's Guide for more information about raidconfig.

If raidconfig is not available on your server, see Oracle Hardware Management Pack for Oracle Solaris 11.3 Installation Guide for installation information.

RAID Capabilities in Oracle Enterprise Manager Ops Center

You can create RAIDs and manage existing RAIDs with Oracle Enterprise Manager Ops Center. If you reconfigure an existing RAID with Oracle Enterprise Manager Ops Center, the contents of the disks in the original RAID will be lost.

For more about Oracle Enterprise Manager Ops Center, see Oracle Enterprise Manager Ops Center Overview.
