The problem is users in building 2 lose their connectivity through quantum servers to our database. Intermittant issue. Usually happens in the morning when it is busiest.

300 users. 3 buildings.
Building 1 hosts 20 servers on GB backbone. 150 users there with 10/100/1000

Building 2 100 users 10/100/1000 linked with 1gb fiber to the Dell 5448 switch in building 1.

Building 3 50 users 10/100/1000 1gb fiber link to building 1.

During the morning we lose our database connection. Our DBA swears nothing is wrong with the software. But the quantums go offline and our DBA suspects network saturation.

so the question is how can I guage if a network segment is saturated on unmanaged switches???

I do a ping -t from building23 to the servers and get <1ms always.

The servers are always below 5% nw utilization.
