[Beowulf] Software RAID?

[Ekechi Nwokah]

Hi,

Does anyone know of any software RAID solutions that come close to the
performance of a commodity RAID card such as LSI/3ware/Areca for
direct-attached drives?

With the availability multi-core chips and SSE instruction sets, it
would seem to me that this is doable. Would be nice to not have to pay
for those RAID cards if I don't have to. Just wondering if anything
already exists.

Thanks,
Ekechi
