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.
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.
