    That’s pretty cool. Synology was definitely a good choice.

    Hey Chris, thanks for the headsup about the plugin. Should check my Syno too and play a bit.
    Regarding “monitoring if VAAI actually gets used” – I don’t have a host handy atm to check, but couldn’t this also be monitored via esxtops device statistics? I know I know “device”, but… esxtop can do so with block storage, so it *should* also easily be able to do the same with file storage now. At least IMHO, but I can’t check for it atm.
    These esxtop VAAI statistics have been of great help already, for instance figuring out performance issues and driver bugs… http://kb.vmware.com/kb/2065193

    I’m finding that only one ESXi host can connect to the NFS share… and that after a reboot the hardware acceleration is “Unknown”.

    Any chance you’ve compared NFS versus iSCSi (block level) for read/write speeds? Not easily done on a whim, given reformat required, just wondering.

    Can you still use this same version of the VAAI plugin for vSphere 6? I’m just curious because Synology still has the older plugin version for 5.5 published and I can’t seem to find a newer version.
