The useful technology of RAID and data recovery services available in India from cases of RAID failures

Soon after large organizations and industries started opting for computers, replacing paper files for their day to day operations, there arose a strong need for a large capacity storage media. As organizations deal with huge volumes of data, single hard drive based systems could not fill in the need. Moreover, with normal hard drives there was always a fear of hard drive failure and loss of data. All these facts led to the invention of RAID.

RAID is a wonderful technology that solved both the problems of data storage and data safety by facilitating storage of huge volumes of data alongside the fault tolerant mechanism. RAID is a technique, with which you can take together multiple hard drives together and build a single system. In RAID, though the hard drives have separate physically memory, but they work as a single logical memory. It has a unique data distribution technique and data is usually distributed across the connected disk drives. All these data storage and access processes are managed by a controller chip, called as RAID Controller.

There are different categories of RAID levels available, depending upon the number of disks and the fault tolerant mechanisms. RAID 0, RAID 1, RAID 5 etc are known to be the simple RAID levels, whereas RAID 6, RAID 6EE etc are termed as the complex ones. Some users even use multiple RAID levels, such as RAID 50 (RAID 5 + RAID 0), RAID 51 (RAID 5 + RAID 1) etc, making the RAID architecture more complex.

In case of RAID level 5 or above, if one disk fails, you can easily replace the troubled disk by a new one and start rebuilding. But, if two or disks fail simultaneously, you are in serious trouble, as a small wrong step can cause permanent loss of data. There are number reasons behind possible RAID failure, some of which are listed below:

  • RAID controller failure
  • RAID Array Failure
  • Rebuild Failure
  • Server Not Booting
  • Hardware Failure
  • Damaged Strip
  • RAID configuration has been corrupt or overwritten
  • Volume/ Partition not found etc.

Many users do not have enough knowledge about the RAID architecture and with experimentation; the RAID failure problem becomes more complex. Moreover, the data recovery from RAID needs huge expertise and advanced infrastructure, which are not affordable on the parts of individual organizations. Hence, for safe recovery of your valuable data, it is advised to take the assistance of any professional RAID data recovery service provider.
