Anyone got an up-to-date OS overview about HP/Aruba switches series?

Hello,

Im wondering if anyone around here is experienced with the HP/Aruba switches line. Because as far as i can remember they went from pure 3COM to some bastard child of 3COM to something barely related to 3COM to something almost entirely not 3COM at all.

Then Aruba "christened" all over the place.

I don't have an HP Consultant at hand to torture about this info.

Thanks
