The LSISAS1078 is a custom chip designed for high performance RAID controllers. It is used on the HP P400 and P800 (their best raid card) as well as an Intel RAID card and LSI logics own "Mega-Raid" brand of RAID card.

I'm sure there are a few XOR's in there somewhere. You're looking for dedicated silicon that can do all the XOR calculations on a block of data very fast. If it's just a general-purpose microprocessor spinning in a loop to do the XOR calculations it will be slower. How many fscking times do I have to say this? -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
