[RAID.sup.n] provides ordable protection against multiple disk drivil failures

LAND-5 Corp's [RAID.sup.n] effectively protects storage arrays from the consequences of random multiple disk drive failures. Available for licensing now, it ensures that mission-critical databases can continue to function regardless of any number of disk drives becoming inoperable. This technology allows system administrators to select the level of "insurance" desired against the failure of one or more disk drives in a RAID array, all the way up to N-1 drives (where "N" indicates the total number of drives in the array). Both "read" and "write" performance for [RAID.sup.n] are on a par with conventional RAID 5 implementations and faster than typical compound RAID 1 5 or RAID 5 5 configurations. Using the same number of disk drives, [RAID.sup.n] provides about twice the data capacity of a RAID 1 5 solution. Both hardware and software implementations are envisioned for this technology which already offers benefits to any application requiring data integrity, such as telecommunications and consumer electronic pr oducts. Initially available in Linux, it can also be easily implemented in other operating systems and at the hardware level.
