    I guess that I don't understand licensing either. On my 840c cluster setup
    the license command reports the same license string for the cluster on each
    head but a different string for both nfs and snaprestore. In fact, the filer
    heads were upgraded from 760's and the netapp tech didn't change the license
    keys when he installed the new ones. (I just opened one of the new envelopes
    this morning.) Also the strings displayed by the license command are not the
    same as what is printed on the sheet supplied by netapp, probably some
    encryption scheme in place here.

    I thought the license keys were different for every machine. Are you saying
    I can use the license key for one machine on another. Aren't they tied to
    serialnumbers?

    I didn't setup the netapps so not sure if they just used one set for each
    head in the cluster. My other cluster has a different license (though both
    heads of that cluster have the same license).

    Anybody else out there with a cluster, what does is listed when you run
    license on each head?

    I figure we will get a 15% improvement in performance if I break the heads.
    How much performance
    improvement have people seen when they have moved from 100mb to gig?

    Keep in mind you won't gain that much. You'll double the write cache, but
    that's about it. If you need more disk bandwidth, toy w/ 3rd party
    adapters -- it'd be too easy compared w/ losing clustering.

    > I noticed they have the same license when I run the license command.

    This is undoubtedly an error -- cluster partners are issued their own
    licenses (except cluster license... can't remember there) -- someone
    probably didn't bother looking for the other sheet of license keys.

    Should work fine, though you probably should open a support case to see if
    someone can dig up the proper license keys for you to avoid trouble in the
    future.
