Currently Coin is running inside a container on a VM located in vSphere. For Coin to storage data, it writes the data on the container on the VM that is actually a vmdk file on the Powerstore. If and when any other VM mounts Coin's storage, it is mounted from the Coin's container which exports its folder. So any data read by some other VM will be read by Coin's VM and then sent from the Coin VM to the reader.

By using the Powerstore's NFS as a storage, all disk operations are going directly to the Powerstore skipping the vmdk entirely. And when a non-Coin VM mounts the storage for reading, it wouldn't need the help of Coin's VM to do that. The access is direct.
