one of my clients owns a supermicro-based box with 4 hot-swap sata bays. it has integrated SATA and (i believe) no SAS. the original admin populated it with (3) 1TB SATA disks and commissioned it as a fileserver (simple raid5). it has 32GB of memory. the box is no longer being used, so it's been allocated to me for the purpose of hosting another windows server. i'd like to virtualize the server via smartos/kvm but i have reservations.
i believe i can get away with using only 16GB for VMs, so that leaves 16GB for smartos/zfs - i think that'll probably work well. but i seriously doubt those disks will give anything resembling decent performance. i only have 4 bays to work with, and only one is currently free. for a windows server VM hosting a multi-user database, would adding a SATA SSD as log device for the zones zpool keep me out of hot water here or is this just not going to work? obviously i can try to source a supported SAS controller and disks, but i'm wondering if i can actually get by with SATA ... what if i filled the (4) 3.5" bays with SSDs and striped across two mirrors? would that mostly guarantee decent performance, or will that just waste time and money? experienced opinions greatfully accepted! ------------------------------------------- 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
