What is RAID and what RAID do you use on your Linux Machines


Raid is a storage mechanism based acronym which refers to Redundant Array of Independent Disks or Redundant array of Inexpensive disks. Mainly RAID is a mixture of hard drives associated and setup in such a way it help to protect and seep up the performance of your systems disk storage. RAID is mainly used on bigger servers and high performance computers.

In other words RAID is the method of merging numerous of Independent and fairly small disks into one single storage of bigger size. The disks comprised into the array are known as array members.The disks can be integrated into the array in various methods which are recognized as the levels of RAID. Each and every levels of RAID has its own unique characteristics of:

Redundancy: Redundancy belongs to having different components which provide the same function, so that the functioning of system can go on with the event of partial system deficiency.

Fault Tolerance: It means, in case of any component deficiency, the system is created a such a way that a backup element will be available, for the purpose to avoid loss of service.

Performance: It shows the variations in the read and write speed of the complete array  in relation to a single disk.

HostingRaja Use Raid 6 on Our Linux Dedicated Servers

We use RAID on our Linux Dedicated server. In RAID 6 the parity data are written to 2 drives. In other words we can say that it needs at least 4 drives and resist two drives dying all together. RAID six mainly has the capability to keep working even if it faces 2 simultaneous disk failures. This is fulfilled by the dual parity drive in RAID 6 giving increased fault tolerance and permitting RAID functions to continue even it faces any failure.

Benefits of RAID 6

There are various benefits and advantages of using RAID 6 parity protection. Some of the top benefits are listed below:


  • Lost data is naturally reformed by the the IOA after a disk deficiency.

  • The system keep working as it is after 2 disks  fail.

  • 2 disk components can be substituted without halting the entire system.

  • 2 disk components of capacity are committed to keeping parity data in a parity set
