Federation promises to bring your storage under control As virtualisation brings IT consolidation back onto the agenda, storage federation is being touted by many as the best way to impose discipline on infrastructures that have grown unwieldy. So what can it offer that storage virtualisation or a global file system cannot, and is it time for us all to join the federation? Storage …
The problem being solved by most storage federation/virtualization vendors is that their money is in your wallet. What they're really trying to figure out how to do is provide the minimum support needed for disparate storage resources so that they can lock you in to their own product. Software-defined storage provides a way out of that trap to a certain extent, but it has the disadvantage (largely perceptual) of not giving you a particular box to kick if something goes wrong. In truth, all storage arrays are "software-defined;" decoupling the software from the storage provides greater flexibility, but it feels more risky.
IMHO, of course.
