Understanding RAID Concepts and Terminology

The following concepts and terminology is commonly used when describing the

functions of the RocketRAID 230x Host Adapter cards.

Disk initialization

Initializing a disk writes necessary RAID configuration information to that disk. Disks

must be initialized before configuring them into RAID arrays. The initialization

process will destroy all data on the disk.

Disk Status

New

The disk contains no data and has not been initialized.

Initialized

The disk has been initialized and can be used for array creation.

Configured

The disk has been assigned to one or more arrays, or configured as a

spare disk.

Legacy

The disk was used on other controllers before use with the RocketRAID

230x (see legacy disk below).
