Very interesting. This also gives me an idea. Using COMSTAR you could build any number of RAM based slog devices. They wouldn't need to be anything amazing, just a bunch of RAM and a supported FC card (or two). > I'm not sure I could survive a crash of both nodes, going to try and test > some more. Ok, so taking my idea above, maybe a pair of 15K SAS disks in those boxes so that you could create a backing store. I wonder what the best way to setup realtime sync would be (without making the backing store responsible for slowing down the ramdisk, so no zfs mirroring between rmadisk and sas disk in other words). > So is this idea completely crazy?
