A few weeks ago I delivered a short L2 DCI WebEx presentation to CCIE Club Poland. I took the L2 part of my Data Center Interconnect webinar and added 15 minutes of L2 DCI mythbusting.

That part of my presentation is on YouTube; for the rest, watch my Data Center Interconnect webinar.

For more details on individual myths, read the following blog posts:

• FCoE over TRILL – this time from Juniper
• The beauties of dense-mode FCoE
• FCoE between data centers – forget it
• Long distance vMotion for disaster avoidance? Do the math first!
• Traffic trombone – what it is and how you get them
• Follow the sun workload mobility? Get lost!
• Stretched clusters – almost as good as heptagonal wheels
• Distributed firewalls – how badly do you want to fail?

Last but definitely not least (trying not to be totally negative), there is a good use case for L2 DCI – running SNA over OTV, because DLSw cannot run @ 10Gb speeds available with the OSA-Express adapters 🤪.
