    S7000 2009.Q4 build

    Evening all.

    just to keep you all informed on the latest developments here at Sun Open Storage...

    I have updated my VB simulator to the pre-release 2009.Q4 build and have just been messing around with it.

    I know you'll badger me senseless on this but it is a great leap forward from the previous versions. Can't say too much on here but when it comes you're gonna love it!

    Anyway, back to playing with zpools (note the "s")

    Chat soon.

    Regards,

    Phil

    I'll buy you a pint in exchange for a rough date on when we'll get post-processing de-dupe?

    Any update on the fletcher-4 hash collision issue?

    Edit: Can you use different dedupe settings per share? Say, set /backups for delayed dedupe over the weekend once full backups have run, /Xen for delayed dedupe during the hours of darkness and maybe dedupe /lightweightusershare on the fly?

    Based on what I heard, on-the-fly de-dupe will add some CPU overhead, but not so much as to make it unusable on most shares. Post-processing de-dupe will be coming later on, not sure if this is something that you'll apply globally as a one-off to a share, or whether you can schedule the post-processing to happy at night or on weekends.

    So the de-dupe stuff is under NDA at the moment as it's 2009.Q4 build which is due by the end of the year at the latest. That means I cannot post any details on here (do I hear a panto "boo! Hiss"?)

    More than happy to chat face to face or webex for those that have NDAs in place.

    Cheers,

    Phil
