Hi guy's,
I don't know if all of you realise what kind of gigantic performance step
IBM has made with the new version of Spectrum Protect for Virtual
Environments for VMware but I think it's pretty incredible.
The magic parameter is VMMAXRESTORESESSION.
See the results below, 1 session was the max that 7.x could do, see the
speeds below when I crank up the sessions.
Remember, this is restoring a single VM on a single datamover using HOTADD.
10 is the max setting for this value, i'm interested to know if you guy's
are seeing the same kind of results.
Oh, and the upgrade was a breeze, if you aren't using the tagging features
it's just next next finish and the restores go so much faster.
