I honestly don't even know if 5-way mirroring is supported, but given your use case, there's no reason to do it. Just do 5x2-way with 2 spares and call it done. You should be overspecified for the performance you need, and you'll have extra capacity as well. 3x3 doesn't get you to your 15 TB requirement. ------------------------------------------- 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
