5.2Configuring Arrays

Connect the physical drives to the MegaRAID SCSI 320-2, configure the drives, then initialize them. The number of physical disk drives that an array can support depends on the firmware version.

For the MegaRAID SCSI 320-2, an array can consist of up to 30 physical disk drives, depending on the RAID level (see Chapter 3 for more information). This controller supports up to 40 logical drives per controller. The number of drives in an array determines the RAID levels that can be supported.

5.2.1Arranging Arrays

You must arrange the arrays to provide additional organization for the drive array. You must arrange arrays so that you can create system drives that can function as boot devices.

You can sequentially arrange arrays with an identical number of drives so that the drives in the group are spanned. Spanned drives can be treated as one large drive. Data can be striped across multiple arrays as one logical drive.

You can create spanned drives by using the MegaRAID Configuration Utility or the MegaRAID Manager. See the MegaRAID Configuration Software Guide for additional information.
