When setting up SSDs to be used as a fast tier storage pool, are people still doing RAID6 LUNs? I think write endurance is good enough now that this is no longer a big concern (maybe a small concern). I could be wrong. I have read about other products doing RAID1 with deduplication and compression to take less than the 50% capacity hit. -------------- next part -------------- An HTML attachment was scrubbed...
