Hi Goswin,
Rack types, or more correctly enclosure types, are defined in the database and there is (yet) no GUI interface to define new enclosure types or edit existing types. I've added a feature request to our issue tracker for this but it might be a while till it gets implemented.
As far as I'm concerned, adding a new rack type is such a rare occurrence that a CLI option would suffice.
Meanwhile if you let us know the specs for your racks (the 47U specifically) I can add them to the predefined racks.
I'll be happy to do so once I have the exact layout, but the racks are located in a different data center, so it wil take a few days.
The Hardware infos for the host are shown as tooltip when you hover over the host in the TreeView on the left. You have configured one of the hardware properties differently to what was detected at boot and comparing the tooltip to the config should show the difference.
OK, got it. The problem was with physical cores vs threads, and I had reduce memory to the rather odd value of 31GB.
Thanks a lot,
A.
