Hello!
I attended a vSphere course recently, where the instructor highly recommended a dedicated management interface. He explained, that for any network interface that is used for vSphere mangement, the vSphere kernel would reserve bandwidth exclusively for the management traffic. In a mixed used vSphere management / VM traffic interface would never provide full bandwidth for the VMs, even then when there is as good as no management traffic. I couldn't find any description in the vSphere documentation. Is there indeed any kind of reserved management bandwidth?
Reason for this question: I have several servers, each with 1 1GbE interface and 2 10 GbE interfaces; first I wanted to use both 10 GbE-ports in a redundant setup, but now I'm thinking about using the 1 GbE-Interface for the management traffic to make sure that no "unused reserved management bandwith" is wasted on the 10 GbE ports.
Thanks in advance for a feedback!
