Understanding RAID Concepts and Terminology

The following concepts and terminology is commonly used when describing the

functions of the RocketRAID 2320 Host Adapter.

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 2320 (see legacy disk below).

Array initialization

A redundant array (RAID 5, RAID 1, RAID 10) needs to be initialized to ensure full

performance and reliability. Non-redundant arrays (RAID 0, JBOD) do not need to be

initialized.

When you create a redundant array using the RocketRAID 2320 controller’s BIOS

Configuration Utility, it will create the array in un-initialized state. The initialization

process can be completed after installing the driver and management software.

When creating an array using the HighPoint RAID Management Console software,

you can specify an initialization option (Skip initialization, foreground and

background).
