Overlay Transport Virtualization

July 24, 2012 at 10:16 am PST

Fresh from the lab, Jimmy Ray takes a question on OTV or Overlay Transport Virtualization.  This layer 2 Data Center Interconnect technology is growing in popularity as deployed on the Nexus 7000 as it promises transparent workload mobility, business resilience and superior efficiency with computing resources. This could be THE technology for those of you overcomplicating your network design or simply not attempting certain architectures for you did not know this could be done.

We featured OTV quite awhile back in one of our earlier Fundamental animations.  See if this also helps you.   Read More »

Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!

Three good stories worth covering, the first two on security!

BYOD Security with Bill McGee

Get more info on the Cisco Security BYOD components, one of which I (humbly) recommend is our ‘Fundamentals of ISE’ (The Cisco Identity Services Engine)

Our second story in security is easily one of my favorites and not just because it involves a lot of friend from Austin.  Cisco’s Security Intelligence Operations…
