This story, Data Center Interconnect Made Simple, is all about connecting multiple data centers together to highlight the virtualized data center model with application and server mobility. This mobility is driven by cloud computing business models, disaster avoidance as well as data center migration/consolidation/planned maintenance. Data Center Interconnectivity helps move virtual machines across pods or physical data center locations with zero business and application downtime. To accomplish this we are focused today on three areas where new innovation is expanding options heretofore not available.
- Layer 2 Extensions. How we can extend layer 2 across vast geographic boundaries and connect remote data centers where the applications operate normally because they see the connectivity they expect. Historically, this meant STP over long distance and it was a nightmare. This changes with Cisco’s OTV or Overlay Transport Virtualization. See this animation we created to get an idea of how this works. Watch the whole show to be schooled by our own Ben Basler.
- Layer 3 Extensions: They are alive and well. Incredible improvements in Advanced VPLS are very much worth considering in the right environment. Amit Singh joing Jimmy Ray in the lab to whiteboard the options here.
- SAN Extensions: are needed to provide virtualized application, access to storage without violating application SLAs (I/O time, latency) regardless of where the application and Virtual machine reside before and after a move. We can’t leave that out of course, Jeff Thomas from EMC joins us to illustrate the need and the ability to deliver cache coherency between multiple storage arrays in these situations.
- Routing Optimization: The impact of these technologies in how we design and implement our networks can be critical. Max Ardica has been working on design guides so we can get on top of the question and the potential pitfalls.
Tough job…but someone has to put all of the above together…so what about those notes?
Well, hopefully not…but do you even know? Knowledge and awareness go a long way these days and with the profit motive driving the criminal activity these days, it pays to be obscure. Welcome to the shownotes for our security episode today featuring Cisco’s Tom Gillis and his new book, Marc Guntrip from ScanSafe for two whole segments (its great stuff), a back to the science lab BOT dissection class with Jimmy Ray and a really cool, did not see that coming, segment on the new LISP protocol with Darrel Lewis, co-chair on the LISP working group.
Welcome to the shownotes for today’s show on Cisco CleanAir. Once again, we have had the privilige of being involved in yet another leap-frog technology that Cisco has rolled out. CleanAir represents one of the better examples of the evolution and development following good acquisition of both technology and talent. In this case, taking the Cognio acquisition from a few years back and working to truly integrate it the capabilities of their spectrum analysis…not just because it may seem like a cool thing to do…but because it is the right thing to do. The thing to watch for here is the network effect however. The analysis and the response capabilities are extremely interesting and impressive but much of the true value is where this is applied in a distributed setting as a service on your network. Mark this moment as another one where we will be able to look back and go ‘remember when?…’ Remember when the data set we worked with was NOT a normal and expected part of doing how you worked with your RF environment?
