Hi,
We have a vmware infrastructure still in version 4 over a HP Blade Center working for some years without problems.
However, 2 days ago we noticed the vms were very slow. We have narrowed down the problem to the network connectivity, though we do not find what the problem is.
On the vms, if we try to ping another server (either in or out of the blade enclosure) it looses a lot of pings. Pinging from the ESX hosts everything is fine with no ping loss.
This happens on all 4 esx servers.
On the other blade servers on the same enclosure (blades not with hypervisor installed) we do not see any problems, and they are working fine. The only blades affected are the esx servers.
No change was made to the environment that could have affected the virtualization servers, nor there was any sw, patch or firmware upgrades done in this infrastructure.
Do you have any suggestions on what this might be, and how to perform troubleshooting on this problem?
Thank and regards,
