With the usual EMC fanfare, VPLEX has been heralded as “a new storage platform“. For a product that appears to contain no storage at all (and in fact writes through to the underlying virtualised arrays before confirming I/O to the host), I can’t quite see how the claim stacks up.

Amid much fanfare and, EMC launched VPLEX today at EMCWorld 2010 in Boston. The company previously outlined the vision for globally-distributed federated storage, but today’s announcement adds both meat and bone to that concept.

I talked about Incipient last year, here and here when discussing the costs of performing migrations.  As [...]
