AOC-USAS-L8i Add-on Card User’s Manual

The menu lists three configuration modes:

•Auto Configuration automatically creates an optimal configuration from the available disk drives.

•Manual Configuration gives you the greatest level of control in creating a new virtual disk.

•Guided Configuration asks you a few simple questions about what kind of configuration you want and then automatically creates it from the available disk drives.

NOTE: You can use AUTO, GUIDED, or MANUAL CONFIGURATION mode to create a RAID 0, or RAID 1 configuration. To create a RAID 10 configuration, you must

use the MANUAL CONFIGURATION mode.

Understanding Virtual Disk Parameters

This section describes the Virtual Disk Parameters that you can set when you use the Guided Configuration or Manual Configuration modes of the Configuration Wizard. You should change these parameters only if you have a specific reason for doing so. It is usually best to leave them at their default settings.

•Stripe Size: A stripe size of 64 Kbytes is supported.

•Disk Cache Policy: Select a cache setting for this disk: Unchanged, Enabled, or Disabled.

•Init State

•No Initialization: The new configuration is not initialized and the existing data on the disks is not overwritten.

•Fast Initialization: MegaRAID Storage Manager software quickly writes zeroes to the first and last 8 Mbyte regions of the new virtual disk.

•Full Initialization: A complete initialization is done on the new configuration. This may take a long time if the disks are large.

Using Auto Configuration

Auto Configuration is the quickest and simplest way to create a new storage configuration. When you select AUTO CONFIGURATION mode on the first CONFIGURATION WIZARD screen, the Configuration Wizard creates the best configuration possible using the available physical disks and displays them in the AUTO CONFIGURATION screen (see Figure 6-5).
