I have been logging some pings to random workstations on my network, and have noticed intermittent spikes in ping times. roughly 5% of the time i am getting ping times between 2 and 6 ms. 1% of the time I am getting ping times between 20 and 40ms.
What could be some of the causes for this? How best to troubleshoot?
4 Dell r905 Servers with 10Gb nics in each
2 Dell PowerConnect 6248's with backplane card and dual 10Gb ports.
Bandwidth utilization on the LAN and the servers even during peak times is very low.
comments and suggestions are appreciated. thanks.
