Description:


It was planned to have a discussion around L2 Data Centre connection the VMworld in Copenhagen but Scott and I could not meetup. So we recorded this podcast to start talking about some of the issues, technology and solutions. I’m not sure that we have all the technology or knowledge in place, so keep watching for more discussions in the future.

This is the second half of the show and you should probably listen to last weeks show to get the whole story at https://packetpushers.net/show-27-layer-two-2-data-centre-interconnect/

  • Greg s article on the Traffic Trombone and Ivan s extensions to it.
  • It s worth remembering that Network Load Balancers can be more effective than using vMotion is certain use cases.
  • vMotion is not for unplanned outages or DR. More for planned outages or possibly workload balancing.
  • Debating whether we are able to QoS L2 traffic when flowing between data centers thus answering the question about guaranteeing levels of service for multiple hosts in a VLAN.
  • Some humour on Pseudowire over MPLS over GRE over IP. But s its actually real.
