ESI Powershell functionality

Hello,

I have about 40 VNX5300's that I need to manage via scripts. I installed the ESI tool in QA but it doesn't do much. I need to do things like powerdown, reverse file replication, create checkpoints, and gather file system info. The ESI is very limited and is not even worth installing in my production environment. Is there some other Powershell module I can use?

Thanks.
