Cisco Demonstrates IPv6 Interoperability

At Cisco, we’ve talked many times before about the exhaustion of IPv4 address space and the need for the industry to adopt IPv6 to support the explosion in the number of people, devices, and web services and enable the continuing growth of the Internet. As you can read in the announcement on our corporate blog, today Cisco joined with other leading industry participants such as AT&T, Google, Facebook, Comcast, and Time Warner Cable to be part of the World IPv6 Launch. This means that by June 6, 2012 all participants will permanently enable IPv6 on their networks and websites.

Since deployment of IPv6 requires an industry-wide response we recently teamed with Excentis to participate in Read More »

From CES to MWC

On my flight home Friday after a full week at the 2012 Consumer Electronics Show (CES), I was reflecting on how mobility is more important than ever before. This comes as no surprise considering the success of consumer devices and our need to be mobile in our day-to-day lives. Now, the real opportunity is how we bring mobility, video and cloud together to create the next generation internet.

At CES, Cisco showed up strong, sharing with customers, the analyst community and the media how we’re making the internet more visual by leveraging the power of Read More »

Ice Ice Baby (Word To Your Data Center Manager)

MPI + VFIO on InsideHPC slidecast

January 18, 2012 at 8:08 am PST

Welcome to 2012!  I’m finally about caught up from the Christmas holidays, last week’s travel to the MPI Forum, etc.  It’s time to finally get my blogging back on.

Let’s start with a short one…

Rich Brueckner from InsideHPC interviewed me right before the Christmas break about the low Ethernet MPI latency demo that I gave at SC’11.  I blogged about this stuff before, but in the slidecast that Rich posted, I provide a bit more detail about how this technology works.

Remember that this is Cisco’s 1st generation virtualized NIC; our 2nd generation is coming “soon,” and will have significantly lower MPI latency (I hate being fuzzy and not quoting the exact numbers, but the product is not yet released, so I can’t comment on it yet.  I’ll post the numbers when the product is actually available).
