Lenovo TD100X manual v Array Configuration Utility, Configuration information and instructions

vThe 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 (for TD100) 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 RAID-8k adapter” on page 117 for details about installing and cabling the ServeRAID-8k Controller to enable RAID level-5 support on simple-swap SATA models.

vThe 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.

vHard 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.

vTo help ensure signal quality, do not mix drives with different speeds and data rates.

vTo 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.

vIf 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 hot-swap SAS or hot-swap SATA redundant array of independent disks (RAID) on the following server models:

vHot-swap SAS

vHot-swap SATA

vSimple-swap models with the optional ServeRAID-8k Controller installed

This utility is part of the BIOS code. The IBM ServeRAID Configuration Utility program adds RAID functionality to the onboard SAS/SATA controller. The onboard SAS/SATA controller comes enabled by default.

Using the RAID Configuration Utility program: Use the IBM ServeRAID Configuration Utility to perform the following tasks:

vConfigure a redundant array of independent disks (RAID) array

vView or change the RAID configuration and associated devices

RAID Configuration Utility menu choices: The following choices are on the IBM ServeRAID Configuration Utility menu:
