Configure off-host SAN based VM backups using 5220

Hello folks,

I understand how to configure a VMware Policy using vStorage API and making 5220 as a backup host and putting in VCENTER credentials.

My question is about zoning the datastores to the appliance.

In order to do san based backups, my datastores are on a SAN.

1. What do I need to do to ensure the appliance traffic goes over SAN?

2. How to do I check if the datastores are being seen by the appliance correctly.

3. Can I zone all the datastores on a single HBA port or split it between HBA ports and HBA cards?

4. What if I have datastore clusters....is the method of zonig them be any different than if they were non-clustered datastores?

Thanks a bunch.
