Requirements When Configuring NAS Devices as Quorum Devices

Recommendations for Network Appliance NAS Device

It is strongly recommended that you use a NetApp clustered filer. Clustered filers provide high availability with respect to the filer data and do not constitute a single point of failure in the cluster.

It is strongly recommended that you use the network time protocol (NTP) to synchronize time on the cluster nodes and the NAS device. Refer to your Network Appliance documentation for instructions about how to configure NTP on the NAS device. Select at least one NTP server for the NAS device that also serves the cluster nodes.

Restrictions for Network Appliance NAS Devices

When configuring a NAS device as a quorum device, you can only add the quorum device when all cluster nodes are operational and communicating with the NAS device.
