IOPS wise it could be close (partially does depend on if you have 12 or 24 15k drives in that 6100XV), but seek time wise that SATA drives would still slow you down. When doing Synchronous replication (from any SAN vendor) you really want the same raid type, same drives, same number of drives or your performance will be that of the slowest raid and drive type.
Hi, I know this works as I have configured it. Won't the performance of the SAS volumes be affected by the SATA. I know the write isn't acknowledged until the the page is in both pools but as the SATA array is slower what will happen. I guess latency will increase?
