RAID is an abbreviation of redundant array of independent drives. If an organization does not operate without a certain level of this type of technology they risk losing data, which leads to them requiring RAID recovery. The business community of today want to protect their data, as they deem them as valuable assets. A business will also take steps to ensure that all data is maintained without the user being aware. This makes raid popular for protecting data and the access of it. Ever since digital computers have been in existence, organisations have looked for technology that would protect and store information. Raid technology was as a result of attempts to generate large storage systems for discs that used small inexpensive drives. The aim being to increase the amount of computer storage capacity, as well as to reduce the response time of computers during the retrieval and storage of data. This resulted in a technology known as raid 0, but it lacked protection from data loss. Raid 5 was later developed for the efficient protection of information.
Raid 5 and How It Works
No less than three disk drives are utilized by RAID 5 in the protection of data contained on either one of the drives. The drives contain an array of information; a computer is continuously implementing equality checks which is a calculation conducted on data bits to scan for errors in information. RAID 5 is unique because parity data is stored on each drive. This assists in the reconstruction of information on the operational drives. The failure of a disc drive within a RAID 5 environment will require RAID recovery you can do this by replacing the dysfunctional drive at the same time as the computer system continuing to gain entry into reconstructed information on the drives that are operational. The process is referred to as a hot swap. After the installation of a new drive, RAID 5 initiates the process which then reloads information and parity data onto the drive.
Avoid Permanent Data Loss by Seeking the Services of a Raid Recovery Expert
There are a number of different reasons as to why a RAID failure may take place, some of the most common reasons include: the failure of RAID array, a strip that has become damaged, configuration damage, a failure to rebuild and the failure of the RAID controller. There are also different categories of RAID which range from 1 to 50, each of them has a different pattern of storage as well as mechanisms for fault toleration. Due to the complexity of this technology it is important to utilize the assistance of a RAID recovery expert when a failure occurs. There are a number of companies that offer such services, to locate one in your area simply perform an internet search, you can also search in your local yellow pages for this information. Be sure to check that the company or individual that you select is qualified to deal with RAID technology due to its sophistication.
