Software Operation ManualRAID 30RAID 30 arrays are formed by striping data across RAID 3 sub-arrays. They offer betterperformance than RAID 3 alone but do not have the speed of a pure RAID 0 array. Storageefficiency and fault tolerance vary depending on the number and size of sub-arrays comparedto the array as a whole. RAID 30 resembles RAID 50 in its characteristics. RAID 30 is bettersuited for use with larger files.RAID 30: Byte striping with parity combined with block stripingCharacteristics:Recommended use:• Capacity: (Size of smallest drive) × (No. of drivesin each subarray - 1) × (No. of subarrays).• Critical multimedia /file servers requiring• Requires a minimum of six drives. Number ofdrives must be divisible by two numbers: 2 orhigher (no. of subarrays) and 3 or higher (driveswithin each RAID 3 subarray)speed, resilience andhigh capacity.• Excellent fault tolerance, increasing with thenumber of RAID 3 subarrays (and hence thenumber of parity disks)Arrangement of data blocks saved on a six-drive Level 30 array- 91 -
