Currently, I have some questions related to the AFS operation and architecture, could you please give me an answer as well as make it clearer in explanation?! Thanks in advance
1. When a client trying to access its data in the AFS share, that client will be connected to the File server cluster represented by an FSVM master or connected to one of the FSVM that responsible for the client data VG?. How can I verify that which FSVM the client is connecting to?
2. The data of client will be distributed across VGs created by AFS or just reside in only one VG in one node?
Could I verify the data of client in that/those VGs?
3. Whether the client data integrity behavior is also the same with any VM data? I mean that data will be copied and back up to other VGs across the FS cluster?
4. The connection and request between client and client data just like the below diagram?
client request CVM FSVM VG?!
5. How can I prove to the customer that Nutanix leverage its own techs and architecture that has lots of benefits and advantage in performance?
6. How can I manage the FS cluster by command and/or dive deeper into FS cluster configuration such as which node containing the FS VGs, in case of one FSVM down, how can I verify that other FSVMs can take over its IP as well as client request...?

You can't delete the volume groups. It's a NO TOUCH ZONE :-)
FSVM is no different than any VM using Acropolis Block Services but it was automated failover - just read the nutanixbible on ABS - http://nutanixbible.com/
you can starting at the below section
The Acropolis Block Services (ABS) feature exposes back-end DSF storage to external consumers (guest OS, physical hosts, containers, etc.) via iSCSI.
