Ah, for some reason @matte I thought your code was mySQL. Okay I just tried it in PowerShell, but it is trying to connect directly to each host rather than just pulling the data from the SnapCenter server itself for some reason. I'm thinking there's likely a way to tell it to gather all it's information from the database. I'll research a little myself but would love to hear any suggestions!
get-smresources : Unable to connect to the remote server : <server_name>
