All raid5 implemetations use different ECC algorithms for this, like Reed-Solomon codes etc. I haven't looked deeply into the code, but it seems there is no any such algrithms implemeted there. Do you just duplicate data on all providers? --=20 Stanislav Sedov MBSD labs, Inc. =F2=CF=D3=D3=C9=D1, =ED=CF=D3=CB=D7=C1 http://mbsd.msk.ru -------------------------------------------------------------------- If the facts don't fit the theory, change the facts. -- A.
