Packet Pushers Podcast

In this Runt Packet we talk to Bob Napaa from Virtensys about their Virtual I/O solution for servers. What’s especially different is that their solution doesn’t use networking…..tune in for mroe details. In the show we cover a lot of topics: How Virtensys connects CPU and Memory to External Resources. Explain key benefits of PCI Bus extension. it’s a standards based technology it’s high performance About the Physical Equipment PCI card into the PCI bus cables that connect to the top of rack Vietensys box Uses standard Ethernet and Fibrechannel adapters in the chassis Management Platform Virtensys also has a GUI management platform. which shows the status, configuration but also has a CLI for power users.

Scott Lowe and I planned to have a discussion around L2 Data Centre connection the VMworld 2010 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 on L2 DCI. I'm not sure that we have all the technology or knowledge in place, so keep watching for more discussions in the future. We have only scratched the surface. If anyone else wants to discuss the topic, please get int contact as more would be better. Because the recording lasted for a hour and a half, we split the show into two parts. This is Part 1 - Layer 2 Data Centre Interconnection where we talk about the problems, challenges. Next week we go into more esoteric topics on vCloud networking, OTV, VEPA and network appliances as virtual machines. Guests Scott Lowe http://blog.scottlowe.org Ivan Pepelnjak http://blog.ioshints.info @ioshints Layer 2 Data Centre Interconnect - open discussion The challenges of extending L2 DCI network betweens sites. Outlining the threats of large Layer 2 spaces in terms of network vulnerability. quick review of vMotion traffic and its requirements. Reviewing the impact of fault domains and L2 VLAN space as uncontrollabl It’s all about the application. Latency, latency and the impact on vMotion switchover. Greg’s ariticle 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. Some review on the F5 EtherIP technology and whether it’s relevant to the solution.

This week we are joined by Ken Henault from HP. Ken is a leader in the VirtualConnect product from HP. In the past, Greg has ranted about the the VirtualConnect product and how crap it looks so we got in touch to 'go at it' and see if he can be convinced that VC has value. How did it go ? ..... you be the judge. Thanks also to the people who tweeted their questions during the recording of the podcast.

This week with talk the Lin Nease, Director for Advanced Technologies for HP Networking.
