Clock accuracy of DL360 Gen8 when NTP is free-running mode

[moto_xxxx]

Hello, Community

Could you please suggest that what is clock accuracy of DL360 gen8 when the NTP is free-running mode?

Otherwise, how can I check the accuracy? Is it described on some documentation?

Thanks for your help

Hi,

The RTC accuracy is +/-2 seconds per day. Most HP servers have same or similar RTC accuracy.

Do refer to the below link for:

Crystal Considerations with Maxim Real-Time Clocks (RTCs)

Note: It is not expected that the server hardware clock would be considered an accurate time keeping device.  The end-user should use NTP server or synchronize with an atomic clock more frequently.

Thanks.

This program will write to a notepad file if you are interested in seeing any errors.

Also, if you are interested in reducing the delay and use a cheap atomic clock, use a GPS with a serial output.

All HP ISS Servers conform to the NTP standards (essentially sub-second accuracy)
