Hi,
we got the following Environment
Bladecener H Chassis with 7 x HX5 MAX Blades with 6 Nics
The Netwrok Swirches inside the Bladecenter are Nortel BT 2-3 Layer Switches 1 GB
The physical Nic's are configured 1000 MB/Bit Fullduplex
The Autonegoiation on the internal Ports of the Nortel Switches is disabled.
The Switch where the external Ports of the Nortel Switch are connected is as Cisco C3560G
At the Cisco Switch and the external Ports of the Nortel Switch is Autonegoiation enabled.
Vsphere 4.1 Update 1 is installed
The virtulal Network Structure is real flat.
We got beside the standard VM Networks for SC an Kernel only one Network which is configured on one seperate vSwitch. The Switch got 2 physical Nic's configured where one is used as StandBy Adapter.
The Scenario:
When i measure the Network througput on 2 VM's on the same Blade i get nearly 1 GB Speed.
Now i move 1 VM to another Blade
When i measure the Network throughput on the same VM's my Network Speeds down to 500 M/Bit an lower.
Normally the Packets should not go through the Cisco Switch. They should be routed inside the Nortel Switch.
Thanks for any suggestions in advance.
Markus
