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 Current Array Type RAID-0 RAID-1 RAID-5 RAID-10 RAID-50 New Array Type RAID-5 or 10 RAID-0 or 5 or 10 RAID-0 or 10 RAID-0 or 5 RAID-0 or 5 or 10 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. 1-8
