For my understanding (system-uplink, data-uplink)

[thorstenn]

Hi,

on the nexus i have the port-profiles "system-uplink" and "data-uplink".

The "system-uplink" is only for traffic between the VSM and the VEM and needs only one NIC connection (better two for HA, right?)

The "data-uplink" is for traffic between the nexus and the VMs, right?

I have eight ports on the ESX hosts. What is a good setup?

2x system-uplink

4x data-uplink

2x vmotion

For the "4x data-uplink" it is useful to create a etherchannel on the nexus and the physical switch?

Thanks and regards

Thorsten

An uplink is any phsyical connection between an ESX VEM host and an upstream switch.

System Uplink - Carries system VLANs - control and Packet

Data/VM Uplink - Carries the VM data traffic

If you want a dedicated one for VMotion thats fine also.  You can dedicate a NIC to VMotion just like you would in a non-DVS set.

Please see below for more info.  There are suggested configuration examples that will help you design your setup.
