Would CCD be a better bet? Are there options I am not aware of. Basically there are five of these guys as Database servers behind ten PowerApp web100 boxes, which in turn are behind a Load-balancing smart switch (CISCO content switch)...we know our main bottleneck is drive access so we wanted some sort of RAID or striping. p.
