Professional RAID recovery in case of Controller failure
RAID consists of a multiple number of low cost hard drives, which taken together as one single logical drive. RAID follows a pattern in distributing data across various drives and are managed by the controller chip. The RAID controller, which is a hardware device is actually incorporates specially programmed controller algorithm to store and manage data across the drives attached to the RAID array. That is the reason, the smooth functionality of the RAID system depends upon the well being of the controller chip. However, in case, the controller of your RAID fails, you need to opt for any professional RAID recovery service to rebuild your RAID.
About the RAID controller:
In general, the RAID controller has two distinguished parts, one is the front-end and the other is the back-end. Where the front-end links to the host adapter, the back-end part establishes the communication with the attached individual disk drives. The RAID controller uses parallel data paths for faster data transfer in RAID arrays(Up to 35 MB per second) and the feature is indeed a noted feature of the same. As the controller manages the functioning of the entire RAID system, any problem to it results serious data loss in RAID.
Significant error messages that signal RAID controller failure:
Among many possible instances of RAID controller failure, below are some of the most common cases, which signal a definite problem with the controller:
Stopping of the write process
Error- “Read ahead buffers timeout”
Error- “Array controller failure
[command failure (cmd= , err=)]” etc.
Under all the above situations, data from one or more drives in the RAID array becomes completely inaccessible and even you can not be able to rebuild the same. Furthermore, any wrong step can add more criticality to the situation and you may end-up loosing data permanently. Therefore, for the sake of your precious data in the drives, it is wise to opt for any professional RAID recovery service provider.
Moreover, RAID data recovery is a systematic scientific operation and obviously a job of an expert. Hence, never ever rely on any inexperienced service provider and avoid experimenting, as about RAID, it is a widely accepted truth that the first recovery attempt has the best chance of maximum possible recovery.
Stellar Data Recovery is a well known RAID recovery service provider in India. With all the necessary assets, for more than 17 long years, Stellar has been rendering its industry best data recovery services to large corporates as well as individuals.
