Adaptec SCSI RAID 2120S/2200S Software User’s Guide
Table 1-1 lists the RAID type migrations supported by Adaptec
Storage Manager.
Table 1-1 Supported Array Migrations
See Chapter 3, Adaptec Storage Manager-Browser Edition , for
instructions on modifying arrays.
Some operating systems, for example Windows XP, Windows
2000, Windows NT and Novell Netware, support Online Capacity
Expansion (OCE). That is, on completion of an array expansion, the
additional capacity can be used without rebooting the system.
Refer to your operating system documentation for instructions on
using the additional capacity.
Drive Enclosures
Adaptec RAID controllers support drive enclosures that include
either SES or SAF-TE enclosure management hardware.
Hot Spares
A hot spare is a drive that is reserved to replace a failing drive in a
redundant array. In the event of drive failure, the hot spare will
replace the failing drive and the array will be rebuilt.
Adaptec RAID controllers support two types of hot spares:
■ 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.
Current Array Type New Array Type
RAID-0 RAID-5 or 10
RAID-1 RAID-0 or 5 or 10
RAID-5 RAID-0 or 10
RAID-10 RAID-0 or 5
RAID-50 RAID-0 or 5 or 10
