Use the IBM ServeRAID Configuration Utility program, Adaptec RAID Configuration
Utility program, and ServeRAID Manager to configure and manage redundant array
of independent disks (RAID). Be sure to use these programs as described in this
document.
The ServeRAID 8k-l SAS Controller that comes with the server (hot-swap SAS and
hot-swap SATA models) enables you to configure multiple physical SAS or SATA
hard disk drives to operate as logical drives in a disk array. The server comes with
a CD containing the ServeRAID Manager program, which you can use to configure
the ServeRAID 8k-l SAS Controller. If your server comes with an operating system
installed, such as Microsoft Windows 2000 Datacenter Server, see the software
documentation that comes with the server for configuration information.
Use these programs to perform the following tasks:
v Perform a low-level format on a hard disk drive
v View or change IDs for attached devices
v Set protocol parameters on hard disk drives
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 SATA models, the server can also
support RAID level-5. See “Installing the ServeRAID-8k adapter” on page 136 for
details about installing and cabling the ServeRAID-8k Controller to enable RAID
level-5 support on simple-swap SATA 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 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.
