This is basically where I was going. There only seems to be one SSD that is considered "working", the Zeus IOPS. Even if I had the money, I can't buy it. As my application is a home server, not a datacenter, things like NFS breaking if I don't reboot the clients is a non-issue. As long as the on-disk data is consistent so I don't have to worry about the entire pool going belly-up, I'm happy enough. I might lose 30 seconds of data, worst case, as a result of running without ZIL. Considering that I can't buy a proper ZIL at a cost I can afford, and an improper ZIL is not worth much, I don't see a reason to bother with ZIL at all. I'll just get a cheap large SSD for L2ARC, disable ZIL, and call it a day. For my use, I'd want a device in the $200 range to even consider an slog device. As nothing even remotely close to that price range exists that will work properly at all, let alone with decent performance, I see no point in ZIL for my application. The performance hit is just too severe to continue using it without an slog, and there's no slog device I can afford that works properly, even if I ignore performance. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
