Nutanix Files uses storage and client networks. The IP addresses are within the user-defined range for VLAN and IP addresses.
Storage network ( Internal Network )
-
The storage network enables communication between the FSVMs and the Controller VM.
-
It also provides access to Nutanix Volumes iSCSI vDisks in volume groups.
-
The storage interface helps manage deployment, failover, and maintenance, and enables control over one-click upgrades.
-
Integration with the CVM lets the FSVM determine if a storage fault has occurred and, if so, whether you must take action.
-
The FSVM service ( minerva_nvm) sends a heartbeat to its local CVM service each second indicating its state.
-
The FSVM service (minerva_ha) sends a heartbeat to the other FSVMs indicating its state.
There will be 'n+1' IP addresses in this Pool, n is the number of File Server VMs. The 1 extra IP is the Virtual IP for the AFS cluster.
Virtual IP : Whichever FSVM is the prism leader will host this IP on interface eth0:1
CVM will communicate to the FSVMs on this IP.
Client network ( External Network )
-
The client network enables communication between the clients and the FSVMs.
-
The client network is also used to communicate with the directory services.
-
The client interface allows clients to connect to SMB shares and NFS exports hosted on a FSVM.
-
A client can connect to any FSVM client network interface to access their file data. If a different FSVM provides the data, the client connection automatically redirects to the correct FSVM interface.
-
If an FSVM fails, the client network address for the failed FSVM moves to another to preserve data access.
There will be 'n' IP addresses in this Pool, n is the number of File Server VMs.
Note: The CVM and FSVM internal IPs should belong in the same subnet.
