We're looking at adding a new server to our network, but want to make sure there are no bottlenecks. With this addition, we are also looking at some new switches. We were told that if we have a switch that is older than two years, that we should look into replacing it. These are Dell PowerConnect 2848 switches, so they're managed and capable of 10/100/1000 on every port, so I'm not really sure if this advice has any merit? What are your thoughts?
