What latency threshold indicates the need for EOC?

I know that one reason to employ EOC is if the size of your network exceeds what can be handled by one SQL instance. However, I also know it can be required if network latencies are too high.

But, what latency values would typically be high enough to indicate the need for multiple databases and the EOC for roll up? What latency can SQL tolerate?

Thank you.

bump. Anyone?

EOC is simply a management console for viewing multiple installations of Solarwinds from one centralized location. My former employer was a managed service provider and we had several instances of SolarWinds running and we used EOC to give our NOC a "one stop shop" so to speak so they could see everything from one. It has nothing to do with latency in the least.

Perhaps I should have stated my question differently. Since latency an be an issue across WAN connections, it can be a reason to install a separate instance of NPM, which would in turn necessitate EOC in order to view those multiple instances. So, what latency values indicate the need for a new instance?

I'm afraid, there is no simple rule of thumb for this. It depends not just on the latency, but also on the number of polled entities, polling frequency etc. In general, the network latency between DB and the poller should be about 10ms. The latest NPM may be able to handle higher latency, but it really depends on your actual configuration.
