Introduction
Spare disk
A spare disk is a single disk that can be used to automatically rebuild a redundant
array in case of drive failure. Spare disks may also be members of a RAID array. Any
available space on these disks may be used to rebuild other broken arrays.
Legacy disk
Disks attached to the host adapter that contain valid partition tables will be identified
as "legacy" disks. A legacy disk attached to the host adapter can be accessed by the
operating system, but cannot be used to create RAID arrays. A legacy disk must be
initialized before assigning it to an array.
Supports RR1640 RAID arrays
The host adapter will recognize arrays created using the RocketRAID 1640 host
adapter. This feature simplifies hardware upgrade procedures, allowing RR1640 users
to take advantage of evolving SATA and bus technology, without having to recreate
arrays, and restoring data from backup.
