RAID Creation

Next recommendations are appropriate and depend on drives’ parameters and vendors.

• The appropriate RAID level depends on the required availability level.

  Level of availability as high as 99.999% can be achieved by using RAID 6 if the RAID consists of less than 20 drives. Use RAID 7.3 with more than 20 drives.

  Level of availability as high as 99.999% can be achieved by using RAID 50 if the RAID consists of less than 16 drives. With more drives, use RAID 60 or RAID 70.
