I have a weird and wonderful problem for you all.
Environment is as follows;
1 x Physical Server HP DL785 G5 running ESXi 5.0
5 x Virtual Servers running Server 2008 R2
1 x HP MSA2000 SAN
- Physical server and SAN connected via fibre.
- Virtual Servers store on SAN
Some of the virtual servers keep dropping packets randomly. I have setup a ping test from my laptop to physical server and vm's, from vm's to physical server etc. It is definitely a problem with the Virtual Server only, connections between all other devices are fine. I have attached a screenshot.
I have tried pretty much everything, deleting and rebuilding the servers from scratch. Changing the NIC types, removing one of the physical NIC's to manage the server. I have also updated the BIOS and firmware of everything in the DL785.
