But if the X25E doesn't honor cache flushes then it really doesn't matter if they are mirrored- they both may cache the data, not write it out, and leave me screwed.
I'm running 2009.06 and not one of the newer developer candidates that handle ZIL losses gracefully (or at all- at least as far as I understand things). As for the optimal performance- a single pair probably won't give me optimal performance- but based on all the numbers I've seen it's still going to beat using the pool disks. If I find the ZIL is still a bottleneck I'll definitely add a second set of SSD's- but I've got a lot of testing to do before I get there. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
