Adaptec's Storage Manager—Browser Edition supports the Adaptec RAID controller features listed below.
Note: Refer to
your controller documentation to verify the features supported by your
controller. Not all controllers support all features.
Automatic Rebuild on Replacement
Adaptec’s Optimized Disk Utilization feature allows you to create an array using a portion or 'segment' of a disk drive. When you create an array, you assign segments of the same size however the segment size does not have to equal the capacity of the smallest drive. Unused disk space is known as 'available space' and can be used in another array. This feature is available only on controllers supporting the advanced feature set.
Adaptec's array reconfiguration feature supports expanding existing arrays, migrating from one array type to another, and changing the stripe size. The following table lists the migrations supported by Adaptec Storage Manager. See also Modifying Arrays. Be sure to check your controller documentation to verify if your controller supports this feature.
Current Array |
New Array |
RAID 0 |
RAID 5 or 10 |
RAID 1 |
RAID 0, 5, or 10 |
RAID 5 |
RAID 0 or 10 |
RAID 10 |
RAID 0 or 5 |
RAID 50 |
RAID 0, 5, or 10 |
Some operating systems for example, Windows XP, Windows
2000, Windows NT and Novell NetWare, support Online Capacity Expansion
(OCE). This allows you to use the additional capacity when the array expansion
is completed without having to reboot the system. If you are using these
operating systems, refer to your operating system documentation for instructions
on using the additional capacity.
Adaptec RAID controllers support drive enclosures that include either SES or SCSI Accessed Fault Tolerant Enclosure (SAF-TE) management hardware.
A hot spare is a 'dedicated' drive assigned to a single array or a 'global' spare assigned to a group of arrays. If a drive in an array fails, the spare replaces the failed drive and the array is rebuilt. Hot spares are appropriate for RAID levels 1, 5, 10, and 50. Be sure to check your controller documentation to verify if your controller supports this feature.
Adaptec RAID controllers support an automatic rebuild on drive replacement. This is useful when a hot spare is not available and the failing drive is an SES or SAF-TE drive enclosure. Enable this feature to automatically rebuild an array when a failed drive is removed and replaced. Be sure to check your controller documentation to verify if your controller supports this feature.
