Can HP just stay and look at Cisco that merges-without-merging with EMC and VMware slipping into the customers data centers that it dominates today? Of course not.
So it buys 3Com. So it starts to push a little more the partnership with Microsoft and the value of Hyper-V on its hardware.
Part of this effort includes the release of a new reference architecture for customers that are interested in installing a Hyper-V virtual infrastructure inside a BladeSystem c7000 and c3000, with ProCurve networking and EVA storage.
To be honest the 23-pages paper seems much more a marketing brochure than a reference architecture.
HP has to do much more than this to compete with comprehensive documentation that VMware/Cisco/EMC are releasing.
