How to secure manila if we share a same storage network?

[Micheal_Philip]

I use a share NAS storage with driver_handles_share_servers=False. I found problem when use same network because VM from tenant-A can access to VM in tenant-B if they have same storage network. So i have question:

1. Can we deploy openstack with mulitple storage network ? Then we can have multiple manila Back end

2. If we have multiple manila backend how to separate these BE to multiple tenant?
