- 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. 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.
