And where does swap go? The default install in Osol 0811 (which is what I just upgraded my home NAS to) gives you a zfs root pool that various things, including swap, are taken out of as filesystems or whatever. (You can then attach another chunk of space to make that root pool mirrored, if you want; I've done that, using two dedicated disks for it.) Actually, I don't think you can really control how the 08-11 install sets up its root. Because of the cost of hot-swap slots in a box, it might make sense to share root and data on two drives, maybe. I haven't gone that route myself. I haven't experimented with SSD in Solaris. I'm using one as the system drive for an XP box, and it's giving me terrible pause problems (I think this is an understood problem, I just bought too early, and haven't been able to afford to junk my current SSD and replace it with an even more expensive one). So make sure to get current research and figure out which ones will be good for what you're doing before spending money! What are your backup plans? RAID (or mirroring) is just the start, to protect you from many hardware issues. (The size of your array makes this more of an issue; mine is two 400GB mirrored pairs, so I can back it up to an external 1TB drive easily.) -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
