Connecting a Dell PowerEdge M1000e to a Cisco MDS9513

Hello,

We are going to be installing some Dell PowerEdge blade servers (with a Brocade M5424 switch) and I have some questions about setting up my Cisco MDS9513 switches to support the storage for the blades.

1.  Is enabling NPIV non-disruptive?

2.  Do I enable NPIV on just the switch (edge) where the blade server will be plugged into or do I also need enable it on my core switch?

3.  Do the ports that I'm going to use for these servers need to be in their own VSAN or can I use an exsisting VSAN?

If anyone has experience with setting up PowerEdge blade servers to a Cisco SAN, any assistance/information will be greatly appreciated.
