v Monitor operation of the RAID controller v Configure a redundant array of independent disks (RAID) array v View or change the RAID configuration and associated devices Consider the following information when using the RAID configuration programs to configure and manage arrays: v The integrated SATA controller (simple-swap SATA models) with integrated SATA RAID (also known as HostRAID) supports RAID level-0 and level-1 when two drives are installed. When the maximum four drives are installed, RAID level-10 is also supported. Note: In addition, when the maximum four drives and the optional ServeRAID-8k Controller are installed in the simple-swap models, the server can also support RAID level-5. See "Installing the ServeRAID-8k adapter" on page 57 for details about installing and cabling the ServeRAID-8k Controller to enable RAID level-5 support on simple-swap models. v The onboard SAS/SATA controller (hot-swap SAS and hot-swap SATA models) supports RAID level-0 and level-1 when two drives and the ServeRAID 8k-l controller are installed. When four drives are installed, RAID level-10 is also supported. When you upgrade to the maximum eight drives and the optional ServeRAID-8k controller is installed, RAID levels 1e, 5, and 6 also are supported. v You can order an optional IBM ServeRAID-MR10is VAULT SAS/SATA Controller that supports RAID levels 0, 1, 5, 6, 10, 50, and 60. You can install the ServeRAID-MR10is SAS/SATA controller only in server models with eight 3.5 inch hot-swap hard disk drives installed. For instructions on how to install the ServeRAID-MR10is SAS/SATA controller, see "Installing the optional IBM ServeRAID-MR10is VAULT SAS/SATA Controller" on page 60 for instructions on how to install this adapter. Note: Note: The onboard RAID controller will be disabled by BIOS when the ServeRAID-MR10is SAS/SATA controller is installed in the server. v Hard disk drive capacities affect how you create arrays. The drives in an array can have different capacities, but the RAID controller treats them as if they all have the capacity of the smallest hard disk drive. v To help ensure signal quality, do not mix drives with different speeds and data rates. v To update the firmware and BIOS code for an optional ServeRAID controller, you must use the IBM ServeRAID Support CD that comes with the ServeRAID option. v If you install a different type of RAID controller in the server, use the method that is described in the instructions that come with the controller to view or change settings for attached devices. Configuring hot-swap SAS, hot-swap SATA, or Simple-swap SATA (some models) RAID Note: RAID options are not supported on the SCO 6.0 and UnixWare 7.14 operating systems. Use the IBM ServeRAID Configuration Utility program to configure and manage redundant array of independent disks (RAID) on the following server models: v Hot-swap SAS v Hot-swap SATA Chapter 3.
