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?

    @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 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..

    Feature Description
    NTP Server List

    The Network Time Protocol (NTP) implementation on the PubSub+ Appliance has added support for up to eight NTP servers.
