Direct NFS Access for Cisco HyperFlex Storage Systems

In this article

If VMware vSphere VMs store their disks on Cisco HyperFlex storages, they access the storage with the help of special Cisco HyperFlex HX Data Platform controllers. The controllers are dedicated VMs deployed on the same VMware ESX host that hosts the VMs.

By default, the controllers are configured to receive traffic only from the ESX host where they are located. To provide communication between Veeam Backup & Replication and Cisco HyperFlex storage, you need to manually enable the Direct NFS access mode between the backup proxy and the controllers.

To enable the Direct NFS access on a data platform controller:

Log on to the controller with an account that has root privileges:

#ssh <user account>@<Controller IP Address>

Enable the NFS traffic from the backup proxy in the iptables.

For example, you can use the following command:

iptables -I INPUT 3 -s <Backup Proxy Data IP> -d <HyperFlex Cluster Data IP> -p tcp -j ACCEPT

Direct NFS Access for Cisco HyperFlex Storage Systems Important!

Veeam Backup & Replication cannot back up VMs that have vSphere or HyperFlex snapshots created.
