Rapid Transit for Mass Storage
RAIT (Redundant Arrays of Independent Tape) are the tape drive equivalent of RAID (Redundant Arrays of Independent Disks) for disk drives. RAIT is sometimes called “tape RAID”. RAIT arrays use the same algorithms that RAID arrays have successfully employed and the motivations for tape arrays are the same as those for disk arrays – much higher bandwidths and increased availability to accompany the parallel movement of large files. RAIT is most beneficial in the HPC, Hyperscale and large enterprise organizations where high-levels of tape throughput and fault tolerance are must-haves, not luxuries. Today’s modern tape drives have much larger 1 GB or 2 GB drive buffers for compressed data making drive synchronization routine. The stage is set for the ultra-high data transfer rates of modern tape technology to redefine throughput levels for all storage systems making rapid transit for mass storage systems become a reality.
