The abbreviation for the RAID is Redundant Array of Independent Disks. This RAID by definition stands for the subsystem for the disks. The expectation for using this is the increment in the performance and the value added services in the reliability. The major purpose of the system is to provide the fault tolerance subsystem which can provide efficiency and reliability to the over all performance of the system. The RAID is also used as a server for the reasons mentioned above. The RAID in the earlier history is also implemented by the software to enable the present abilities.

Since the purpose of RAID is for fault tolerant systems hence the design is suited for that purpose. The RAID technology is actually a set of standards. These standards are required to be followed for developing a fault tolerant storage system. The performance also matters a lot here. Hence in the mentioned above paragraph it is said that RAID has been implemented by only the software. The set of standards should be kept in mind before implementing the RAID. This is done using at least two ordinary hard disks and a RAID controller. The discussion regarding the RAID controller shall be dealt with in the upcoming sections.

The RAID has its origin starting from the year of 1980. At that time it was referred as the Redundant Array of Inexpensive Disks. This was in comparison with the storage system available at that time. The storage devices where quite expensive those days; so the implementation of a secure RAID drives was an important enhancement in the field of storage systems. Presently the prices of the memory whether it is the secondary memory like the hard disk, floppy drive, compact disk or any other storage media as well as the primary memory storage like the RAM etc, are all decreasing day by day. Hence by these statistics the RAID Advisory board modified the parameters from inexpensive to the independent.

The concept of mirroring and parity is also available in the RAID drives. In fact the property of fault tolerance is achieved by the process of mirroring and fault tolerance. The achievement is quite necessary for the purpose of providing a fault tolerant system.

The RAID system may have an altogether different drive for the sole purpose of replacing the drive that is failed or might have crashed. The RAID is drive that is replaced and is in spare is called as the hot spare. The hot drive is used in the case of an emergency where in the drive is the spare part that is used to fill in the gap provided by the crashed systems drive. Such a drive must always be ready and waiting. The physical state of such a drive is of quite importance where in the drive must be made available for the purpose of providing back up to the system. The replacement should be carried out immediately. So after the replacement is carried out now the entire system must be made aware of the fact that the hot spare drive is in use. And also the provision should be made for filling up the gap made by the hot spare drive. This is necessary if the other drives also fail and the condition is also possible even if the hot spare drive itself fails. But the RAID continues to dominate the technology that is used for the implantation of secure systems.
