discovery mid server placement

[Ravish Shetty]

I am aware of the best practice to keep mid servers close to the locations where the devices are placed which need to be discovered.

We are targetting 2 locations for now (A and B). I have provisioned one VM for A and another for B.

The network team has advised that as A and B are in the same VLAN, we need not have 2 MID servers and one should be enough. Is this accurate?

The physical distance between A and B is 20 KMs or 12.5 Miles.

Hi Ravish -- correct, you don't need a MID server on every Vlan.  As long as ports are open and IP traffic is allowed to flow between the MID and the targets to be scanned, its possible to have a MID instance scanning a bunch of subnets/vlans.

Hope this helps?

My main concern there would be snmp, which is run over UDP.

If they start dropping your snmp packets, discovery is going to get spotty fast.

The question there might be how far apart are A and B physically and what is the latency between them.

point to point would be 20 KMs (12.5 Miles)
