This tool allows an architect to design a RAID (redundant array of inexpensive disks) storage system. Given the total number of disks available and the level of RAID desired the designer is given the storage efficiency.

RAID Levels

RAID 1 -- Disk Mirroring
RAID 2 -- Bit Interleaved Redundancy
RAID 3 -- Bitwise Parity
RAID 4 -- Block Parity
RAID 5 -- Interleaved Parity Sectors

Input Values:

Total number of disks available disks = disks
RAID level (1-5) level =


Storage Disks storage = Disks
Redundant Disks redund = Disks
Storage efficiency effic = %
