The SSD -C version with 15 x Intel S3700 800 GB SSD is pretty crazy. How do you guys chop these up? Pair of RAIDZ2 with a hot spare? What do you do with the spare slot 15 out of 16? How about the 12 x UltraStar 7K4000? What raid layout do you use for those nodes? Couple of the chassis (-A,-C) seem to be direct attach. I assume this is because of performance, particularly with the SSD node. ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
