For the last few weeks, we have been seeing connectivity warnings for 2-3 minutes ata time for unkonwn reason (colo says everything is fine, our IT manager says there is nothing wrong with the severs..
Where should we be looking to rule out the switch as the source of the problem? We are in the process of setting up Nagios/Cacti in the next week to collect more info.
Also, IT is asking for a new layer 3 switch, is this really neccesary with 6 server, san, tape drive?
