Darren, Perhaps I misspoke when I said that it wasn't about cost. It is _partially_ about cost.
Monetary cost of drives isn't a major concern. At about $110-150 each. Loss of efficiency (mirroring 50%), zraid1 (25%), is a concern. Expense of sata bays, either in a single chassis or an external chassis is a concern. Expense of replacing entire pool sets of disks to grow is a concern. At this point zraid seems to be my only choice if I want 3TB of actual space. I may gain some benefit by using compression. Windows Home Server doesn't help me because I want xvm, iscsi and nfs. But the 'features' of WHS do approximate this fantasy setup I outlined. Mirroring: Let me see if I'm understanding your suggestion. A stripe of mirrored pairs. I can grow by resizing an existing mirrored pair, or just attaching another mirrored pair to the stripe? This gives me growth capability at the cost of 50% disk capacity and requiring a large amount of sata ports/bays. I'm still holding out for an answer to my original question. :) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
