    Well, this is all very encouraging! I guess there is interest and actual
    usage out there.

    Unfortunately, I need FDR-ish speeds (at least 4GB/s), the entire network
    is setup for FDR, and I only have ConnectX-3 adapters, so it's Linux for me
    until some new developments emerge.

    Dan, I can somewhat vouch for the stability of ZFS on Debian and CentOS
    using the ZoL kernel implementation. My Debian system (the one using IB) is
    at 65 days uptime with a 24/7 heavy load, managing 100TB+ of datasets in a
    quasi-production (replicated) environment. First disk replacement went
    smoothly last week. Time will tell... The CentOS install has been up for
    close to a year. However, in terms of raw disk access speeds, neither of
    these systems performs anywhere near as well as OmniOS or OI.

    Thanks, all. I look forward to joining the conversation here in general.
