NTP Servers load balanced on GTM

Hi,

 

We are planning to load balance our NTP servers through GTM. We have 2 NTP servers, one in each DC.

 

Is it possible to load balance on GTM, if yes, what health monitor will be used for this NTP Virtual Server?

 

application delivery
BIG-IP
BIG-IP DNS

    Yes it is possible to load-balance NTP servers over GTM. You just need to use Topology as Load-balance method, so that request from different locations get directed to their respective NTP servers. You can setup any monitor starting from ICMP to TCP to http. Just that HTTP will just have extra unwanted overhead. So you can go with TCP or TCP-Half open.

      Thanks Amrit.

       

      Also is it possible to add a physical server in the pools?, coz normally we would add virtual servers in the pools as pool members.

       

      Apologies for such simple questions, i'm just new to GTMs... just needed to be clear before moving further with the plan..

      No issue buddies. Every journey has a beginning... :) Yes you can add Physical servers as well as pool members. You just need to define them as Servers with Product type as 'Generic host'. gtm server { product Generic Host }
