And along those lines, why stop at SSD's? Get ZFS shrink working, and Sun could release a set of upgrade kits for x4500's and x4540's. Kits could range from a couple of SSD devices to crazy specs like 40 2TB drives, and 8 SSD's.
And zpool shrink would be a key facilitator driving sales of these. As Jordan says, if you can shrink your pool down, you can create space to fit the SSD devices. However, shrinking the pool also allows you to upgrade the drives much more quickly. If you have a 46 disk zpool, you can't replace many disks at once, and the upgrade is high risk if you're running single parity raid. Provided the pool isn't full however, if you can shrink it down to say 40 drives first, you can then upgrade in batches of 6 at once. The zpool replace is then an operation between two fully working disks, and doesn't affect pool integrity at all. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
