Hello,

I have a Brocade SAN fabric (DCX-8510-8 switches ) in current datacenter. I would like to migrate  to a new datacenter which is 100km away using broacde extended fabrics. Here is the plan. Please tell me if this will work:

1. Install new DCX-8510-8 switches in new datacenter and connect new storage array to this fabric.
2. Lay dark fiber between new datacenter to the current datacenter.
3. Connect the DCX-8510-8 core switch of current datacenter to the DCX-8510-8 core switch of the new datacenter and configure brocade extended fabrics so that the switches in the new datacenter join the existing fabric of the current datacenter.
4. Zone the hosts in current datacenter to the storage in the new datacenter.
5. Provision storage from new datacenter to the host in the current datacenter.
6. Host now is receiving storage from current datacenter and new datacenter.
7. Copy data host based from current datacenter and new datacenter.
8. Move host to new datacenter.

Questions:

1. Can host access storage 100kms away using brocade extended fabrics?
2. Is there any special hardware required (swiches, SFPs, licenses) to implement this?
3. What are the caveats?. If any?
