Hey, with EMC and Avamar you can now have also VM (almost) Instant Access, so why do you care about Veeam support? Oh, right, you need to also use a DD to make it work
(obviously, I'm kidding).
The original poll
is almost two years old, things have changes meanwhile, for example I suspect the ratio between clariion and vnx is now the opposite. And we do not now about other storages being supported while we speak, even if are less common than others (see the original percentage of 3par in that poll...).
There are also strategic alliances involved in this kind of integration I think, it's not only a technical issue.
