Configuring NTP servers

When the cluster is initially set up, primary and secondary NTP servers are configured to provide
time synchronization with an external time source. The list of NTP servers is stored in the Fusion
Manager configuration. The active Fusion Manager node synchronizes its time with the external
source. The other file serving nodes synchronize their time with the active Fusion Manager node.
In the absence of an external time source, the local hardware clock on the agile Fusion Manager
node is used as the time source. This configuration method ensures that the time is synchronized
on all cluster nodes, even in the absence of an external time source.
On X9000 clients, the time is not synchronized with the cluster nodes. You will need to configure
NTP servers on X9000 clients.
