Rapid RAID Rebuild
Improving system availability
The capacity of disk drives is growing significantly faster than the data rates to the drives; the result of this is the time to rebuild a RAID group, when a disk drive fails, is extended to many hours. Rapid RAID Rebuild is a NetApp technology that combines the drive monitoring and global hot spare. When potential failure of a drive is detected, Rapid RAID Rebuild enables the contents of the potentially bad drive to be copied in the background to the hot spare before failure occurs. If the flagged drive should fail before the full contents are copied, then only the remainder needs to be rebuilt from parity calculation, dramatically reducing the time to full recovery.
This background rebuild does not incur the performance penalty that a normal RAID rebuild inflicts on users and applications.
Rapid RAID Rebuild is part of the Advanced Protection Architecture and is just one of the ways that StoreVault delivers peace-of-mind data storage, allowing you to spend more time on your business and less time worrying about your storage. [more »]
