Live Storage Migration?

[esnmb]

I am reading over the performance documentation for vSphere 5 and don't understand somethign.  "Virtual machines are no longer pinned to the storage array they are instantiated on."  I have two different SANs attached to my Clusters and I can storage vMotion between them.  I think I must be missing something.

I believe what is being described is storage DRS - where you can cluster LUNs and have vCenetr 5 Storage vMotion based on IO requirements -

Possibly, though even VMware's recommendations says dont put LUNs from different arrays in the same Storage Pool.

It could also be a reference to the new under-the-hood stuff for Storage vMotion (mirror driver).

In the launch presentation it seemed to be suggested that storage DRS would storage vMotion VMs if a LUN was too loaded.

I'd love to test this as there is at first sight a very obvious problem with that.

But remember that this is only an Enterprise+ feature... so not for all.
