Has anyone encountered a problem similar to the following?
Server: HP DL360 G7
NIC: Onboard 4 port Broadcom NC382i Integrated Quad Port PCI Express Gigabit Server Adapter
NIC: Intel NC364T PCI Express Quad Port Gigabit Server Adapter
Host: ESXi 4.1 (Build: 260247)
All 8 ports of the ESXi server is connected to a 3750 which is configured as a stack with 3 x 3750 in total.
Ports 1 to 4 for the onboard NIC is connected to Switch 2 (3750) ports 1 to 4 and the Intel ports are connected to 5 to 8.
What I'm noticing is that the speed in which the ports are connected to are not all Gb. I've tried configuring auto negotiate on the switch and the host and forcing the other side to Gb and I would only get 1 to 2 ports connect at 1Gb. The others would become disconnected. What's strange is that this is not consistent with the other ESXi server with the same configuration (there are 2 x DL360 G7) so for instance:
ESXi01
vmnic ports:
0 - 1000
1 - 100
2 - 100
3 - 1000
4 - 100
5 - 1000
6 - 100
7 - 100
ESXi02
vmnic ports:
0 - 1000
1 - 100
2 - 1000
3 - 100
4 - 100
5 - 100
6 - 1000
7 - 100
I cannot find any consistency in what is going on after pulling cables left right and center. I think I've tried all combinations of auto negotiate and had coded settings without being able to figure out a pattern as to why this is happening.
I'm beginning to wonder if this is because all 8 ports are connected to a single 3750 in a single stack and I would prefer not to go with port channeling for this environment (tried that and couldn't get it going either).
Also, I've confirmed with the network engineer on the switch side that he has configured the trunk ports are per VMware's KB.
Any suggestions are welcomed as I'm extremely curious why this is happening.
Thanks.
