Here's the reason why...
Vmware - although the traditional industry standard, expensive in comparison to HyperV or Citrix Xen. Now that the competition has caught up in much of the functionality, customers are less interested in paying a premium for a commodity software.
Cisco - struggling as a company right now, with a massive mis-step with the Nexus technology, plunging margins and layoffs in an industry which is looking at flatter, simpler and low-latency networks instead of a newer version of the same old proprietary stuff. As for servers, most companies would rather have the #1, #2 or #3 vendors HP, Dell and IBM instead of someone who falls behind Supermicro in their unit sales.
EMC - Network Appliance loves this amalgam of dysfunction because they reckon it sells more NetApp than EMC gear, if/when customers are falling for it. EMC's struggling to justify frames when the functionality in this environment is in the Vmware core and the traditional SAN is an overkill.
What else? Rigid designs like this are very last decade. Any time you need to set up a separate company to implement supposedly industry standard gear should stand as a warning to any prospects.
