How to configure an NTP Server on E-Series

Last Updated:

Applies to

  • E-Series
  • SANtricity OS Controller Software


  • Network Time Protocol (NTP) is configured for automatic synchronization of the controller clocks with an external host using Simple Network Time Protocol (SNTP).
  • When this feature is enabled, the controller periodically queries the configured NTP server, then uses the results to update its internal time-of-day clock.
  • If only one controller has NTP enabled, the alternate controller periodically synchronizes its clock with the controller that has NTP enabled.
  • If neither controller has NTP enabled, the controllers periodically synchronize their clocks with each other.

Note: You can use a static IP address, either IPv4 or IPv6 addresses, to obtain an IP address from a DHCP server, or you can use a domain name as long as a DNS server is also configured.
