May I ask you a question about your setup?
It seems that you have a VSA on each ESX server in production?
Where did you place your Media Agent? Do you have dedicated Backpu network?
Sorry for asking about details but it is intersting to see how scaling works in other setups.
The way we have set it up :
- One dedicated ESX Mount proxy for 20 ESX Hosts.
- SnapProtect is used to mount NetApp snapshots to this ESX hosts
- Single VM containing VSA and MA used for HotAdd and NBD transport to push data to remote Disk Library (CIFS share)
This is a brand new environment and we are looking into possible scenarios for scaling so your setup is interesing for us.
