Hi all,
I've two ESX, HOST A - HOST B, whit gigabit network card on gigabit infrastructure.
The network cards of both hosts are recognized in gigabit, but the speed of data transfer on HOST B is comparable to a 100Mbit. I changed the cables, the ports on the patch panel and the switch: no results. All physical adapters should be the same speed (wrong) but in the vSphere client are "certified" to gigabit.
The virtual switches are configured exactly like those of the HOST A
