Hello zfs-discuss, While waiting for Thumpers to come I'm thinking how to configure them. I would like to use raid-z. As thumper has 6 SATA controllers each 8-port then maybe it would make sense to create raid-z groups from 6 disks each from separate controller. Then combine 7 such groups into one pool. Then there're 6 disks remaining with two of them designated for system (mirror) which leaves 4 disks probably as hot-spares. That way if one controller fails entire pool will still be ok. What do you think? ps. there still will be SPOF for boot disks and hot spares but it looks like there's no choice anyway.
