Last year, there were discussions on this list about the possible use of a 'co-processor' (Intel's IOP333) to compute raid 5/6's parity data.
The MD patches have been posted for review, and the hardware offload pieces are nearing completion.
We are about to see low cost, multi core cpu chips with very high speed memory bandwidth. In light of this, is there any effective benefit to such devices as the IOP333?
It is true that upcoming server platforms have an abundance of CPU cycles, but what about the case where an IOP is the host processor? This is the primary target of the current work. Also, what about the more expensive RAID6 conditions (2-failed disks) where there might be benefits to having MD split its work over many CPUs?
