Hello Trevor,
As of Saturday Jan 29th 2011, our support hasn't changed except for the "phone home" number that our systems automatically dial into to report status and errors.
That said, I expect there to be some changes eventually. It's safe to assume there are some duplication of efforts between the two companies that will be resolved in time. There's no way to know what will happen, but I from all appearances, I think HP Storage operations will become more like 3PAR's and less like HP of old
since the CEO of 3PAR is the new leader of HP Storage(works).
