Which SolOs support 2 NTP Server (Active/Backup) configuration for Appliance ?

This is required for redundancy purpose, I know workaround but more interested to know if in recent SolOs we have such feature!

@Abhishek , I don't believe multiple NTP servers are supported (yet) on Solace appliances. Just curious .. whats the workaround you have in mind?

Abhikesh

@nram we can leverage Virtual IP Address.
VIP will be mapped with 2 NTP Server (Active/Backup).

I am confirming that configuration of multiple NTP servers is not currently supported on SolOS appliances.

Abhikesh

Thanks @brenda for Confirmation.

@Abhikesh I believe you could go this route as from a Solace Broker perspective it will just recognize the VIP as one NTP server. That said, there are some considerations to this approach in general - there is a concise summary here: https://serverfault.com/questions/805939/ntp-high-availability-behind-a-virtual-ip

Thanks @marc, after reading this https://serverfault.com/questions/805939/ntp-high-availability-behind-a-virtual-ip, It seems VIP NTP will do more harm than good if proper considerations didn't taken..
