Running more than one array on a given physical drive or set of drives is called a sliced configuration. The only drive that the operating system Intel ir3 1078 SAS Hardware RAID with is the virtual disk, which is also called a virtual drive. The RAID controller is the mastermind that must configure the physical array and the virtual disks, and initialize them for use, check them for data consistency, allocate the data between the physical drives, and rebuild a failed array to maintain data redundancy.

The features available per controller are highlighted later in this document and in the Intel ir3 1078 SAS Hardware RAID guide for the RAID controller. The common terms used when describing RAID functions and features can be grouped into two areas: Fault tolerance describes a state in which even with a drive failure, the data on the virtual drive is still complete and the system is available after the failure and during repair of the array. Most RAID modes are able to endure a physical disk failure without compromising data integrity or processing capability of the virtual drive.

RAID mode 0 is not fault tolerant. With RAID 0, if a drive fails, then the data is no longer complete and no longer available.

Backplane fault tolerance can be achieved by a spanned array where the arrays are on different backplanes. True fault tolerance includes the automatic ability to restore the RAID array to redundancy so that another drive failure will not destroy its usability.

True fault tolerance requires the availability of a spare disk that the controller can add to the array and use to rebuild the array with the data from the failed drive. This spare disk is called a hot spare.

It must be a part of the array before a disk failure occurs. A hot-spare drive is a physical drive that is maintained by the RAID controller but not actually used for data storage in the array unless another drive fails.

Upon failure of one of the array s physical drives, the hot-spare drive Intel ir3 1078 SAS Hardware RAID used to hold the recreated data and restore data redundancy. There can be more than one hot spare per array and the drive of the closest capacity is used. If both dedicated and global hot-spare drives are available, then the dedicated drive is used first. If the hot swap rebuild fails, then that hot spare is also marked failed.

Since RAID 0 is not redundant, there is no hot spare value. If a hot-spare drive is not an option, then it is possible to perform a hot or cold swap of the failed drive to provide the new drive for rebuild after the drive failure.

A swap is the manual substitution of a replacement drive in a disk subsystem. If a swap is performed while the system is running, it is a hot swap. A hot swap can only be performed if the backplane and enclosure support it. If the system does Intel ir3 1078 SAS Hardware RAID support hot-swap drives, then the system must be powered down before the drive swap occurs. This is a cold swap. In all cases hot spare, hot swap, or cold swapthe replacement drive must be at least as large as the drive it replaces.

In all three cases, the failed drive is removed from the array. If using a hot spare, then the failed drive can remain in the Intel ir3 1078 SAS Hardware RAID.

When a hot spare is available and an automatic rebuild starts, the failed drive may be automatically removed from the array before the utilities detect the failure. Only the event logs show what happened. If the Intel ir3 1078 SAS Hardware RAID is shut down during the rebuild, all rebuilds should automatically restart on reboot.

Data Redundancy Data redundancy is provided by mirroring or by disk striping with parity stripes. Disk mirroring is found only in RAID 1 and With mirroring, the same data simultaneously writes to two disks.

If one disk fails, the contents of the other disk can be used Intel ir3 1078 SAS Hardware RAID run the system and reconstruct the failed array. Until a failure occurs, both mirrored disks contain the same data at all times. Either drive can act as the operational drive. Parity is the ability to recreate data by using a mathematical calculation derived from multiple data sets.

Parity is basically a checksum of all the data known as the ABCsum.
