RAID Array Failures & Recovery

RAID Arrays Failures & RecoveryA hardware RAID implementation requires at minimum a RAID controller. On a desktop system this may be a PCI expansion card, PCI Express expansion card or built into the motherboard. Controllers supporting most types of drives may be used – IDE/ATA, SATA, SCSI, SSA, Fibre Channel, sometimes even a combination. The controller and disks may be in a stand-alone disk enclosure, rather than inside a computer. The enclosure may be …

RAID 6 — Do you really like it?

RAID 6For several years now RAID 5 has been one of the most popular RAID implementations. Just about every vendor that supplies storage to enterprise data centers offers it, and in many cases it has become — deservedly – a well-trusted tool. RAID 5 stripes parity and blocks of data across all disks in the RAID set. Even though users now must devote about 20% of their disk space to the …

The advantages and disadvantages of RAID 5EE

RAID 5EE is very similar to RAID 5E with one key difference — the hot spare’s capacity is integrated into the stripe set. In contrast, under RAID 5E, all of the empty space is housed at the end of the array. As a result of interleaving empty space throughout the array, RAID 5EE enjoys a faster rebuild time than is possible under RAID 5E.

RAID 5EE has all of the …
