I see “one-to-one” configurations used for Management and vMotion networks way too often, where a vMotion network will use one physical uplink, and Management will use the other, that’s it–
It’s a common configuration, and exists in environments of all sizes. Unfortunately, it represents a single point of a failure, and the potential for a really bad day if the Management network drops and your HA configuration starts shutting down your virtual machines.
And it’s so easy to fix!! Check out the video below to see the “problem scenario” and how easy the solution is to implement.
The VMware Networking team mentioned this as a VMware development in the works–
Wireshark Plug-ins . Wireshark is a great tool for frame-by-frame dissection of your network traffic. You can just install Wireshark in a Windows or Linux guest VM on a promiscuous vswitch port and away you go (select appropriate VLAN via the Port Group or all with VLAN=4095). The plug-ins add additional protocol dissectors so you can get analyses of VMotion, HA heartbeats, FT logging and so on (look at Howie’s presentation for some screenshots ).
Would you believe that your everyday users could pose the biggest security risk to your company? I know, I know, that’s impossible. People never share too much information or put convenience over security– ever.
