Introduction Array Level Migration Adaptec RAID controllers support migration from one array type to another (provided your controller supports the new array type). The migration possibilities are; Current Array Type RAID 0 RAID 1 RAID 5 RAID 10 New Array Type RAID 5 or 10 RAID 0 or 5 or 10 RAID 0 or 10 RAID 0 or 5 For details on how to migrate from one array type to another, refer to the Adaptec Storage Manager online Help. Drive Enclosures - SCSI only Adaptec SCSI RAID controllers support drive enclosures that include SAF-TE enclosure management hardware per the SAF-TE specification. Hotspares Adaptec RAID controllers support hotspares-drives that are reserved to replace a failing drive in a redundant array. If a drive fails, the hotspare will replace it and the arrays is automatically rebuilt. Adaptec RAID controllers support two types of hotspares: ■ Global-Protects every array that the drive has enough available capacity to protect. ■ Dedicated-Protects only the array that it has been assigned to protect. 1-9

Introduction
Array Level Migration
Adaptec RAID controllers support migration from one array type to
another (provided your controller supports the new array type). The
migration possibilities are;
For details on how to migrate from one array type to another, refer
to the Adaptec Storage Manager online Help.
Drive Enclosures –
SCSI only
Adaptec SCSI RAID controllers support drive enclosures that
include SAF-TE enclosure management hardware per the SAF-TE
specification.
Hotspares
Adaptec RAID controllers support hotspares—drives that are
reserved to replace a failing drive in a redundant array. If a drive
fails, the hotspare will replace it and the arrays is automatically
rebuilt.
Adaptec RAID controllers support two types of hotspares:
■
Global
—Protects every array that the drive has enough
available capacity to protect.
■
Dedicated
—Protects only the array that it has been assigned to
protect.
