There has been a lot of chatter on the blog verse about so called vendor blockers (I think you can shorten that to vblock).
This is the idea that a pre-blessed solution is the safest way to build infrastructure in the data centre.
I can see the attraction, but I suggest the best way to get there is with the vendor who is most willing
to work with the widest range of their competitors.
And you cannot get much wider than IBM SVC.
IBM has been supporting SVC in a mixed OS and hardware environment since 2003.
The IBM Storwize V7000 inherits all of the interoperability testing done over 7 years with IBM SVC.
This is an astonishing way to bring a new product into the marketplace.
I cannot think of a new midrange entrant that has somehow managed to get the same level of
interoperability testing and ISV integration on the very day of its birth.
When you look at the picture below you can see the depth of IBM's support matrix for SVC and its
cousin, the Storwize V7000.
I have on occasion raised a laugh from an audience when I describe IBM SVC as a vendor independent virtualization layer.
But the picture doesn't lie... with the IBM Storwize V7000 or IBM SVC... there is no vendor blocking.
Plus with the ability to move your data out of the IBM virtualization layer (using the the migrate to image command), you can
remove IBM from the picture at any time... meaning no vendor blocking... and no vendor locking.
