It’s been a very busy few weeks. The Data Storage Innovations (DSI) conference, the Ethernet Summit conference, EMCWorld, and next week at CiscoLive, I’ve been starting to talk about a new concept in Data Center storage networks called Dynamic FCoE. Understandably, there have been a lot of questions about it, and I wanted to try to get this blog out as quickly as possible.
The TL;DR version: Dynamic FCoE combines the best of Ethernet Fabrics and traditional deterministic storage environments to create massively scalable and highly resilient FC-based fabrics. If you thought you knew what you could do with storage networks, this takes everything to a whole, new level. Read More »

The increase in enterprise data storage needs coupled with longer data retention periods (mandated by legislation and compliance regulations) is leading to large growth in storage infrastructure: more backup, complex archive and disaster recovery, and increased requirements for resources, such as space, power, cooling, storage, and personnel. While businesses are trying to reduce their CapEx and OpEx, they are challenged to lower their storage infrastructure investments. In order to be more responsive in a highly competitive marketplace, organizations are transforming to support the 21st century needs, by being more agile and efficient in delivering centralized applications and services to a geographically distributed customer base. To accomplish these goals, organizations are consolidating data centers, adding virtualization technologies, and leveraging cloud architectures. These initiatives, along with others, are imposing significant strain on storage networks
Now the question is how do you consolidate and virtualize Storage efficiently and support DC transformation? Is it by enabling FC or FCoE or iSCSI or NAS ?
May be, the answer is — “Multi-protocol Storage”… To provide highest reliability, scalability, and performance, organizations have traditionally deployed Fibre Channel storage networks and some will continue to do so. FC is still the preferred choice for enterprise (large and small) and market transition from 4/8 G to 16 G is the best proof that FC market is strong and growing. While FC is growing, Ethernet based Storage solutions ( i.e.FCOE, iSCSI etc) is also gaining mindshare and some of our progressive customers use end to end FCOE and other Ethernet based Storage protocols to reap benefit of convergence. Cisco solution enables true convergence by combining the power of Ethernet and Fibre Channel (FC) technology.

It’s been a long time coming, it’s true. It was long the #1 request I have gotten when it comes to Cisco’s deployment for Fibre Channel over Ethernet (FCoE): when is UCS going to have “FCoE Northbound?”
Now, at long last, I can confirm that the answer is right now.
I saw the announcement over the weekend, and before I had a chance to even sneeze out a tweet of my own, I was beat to the punch by a few other intrepid UCS fiends. The reaction was one of unadulterated joy and pure, rapturous bliss.
Or something close to that.
In all seriousness, from a storage perspective the one thing that has driven people crazy is the fact that the UCS Fabric Interconnects (FIs) could not continue with convergence upstream. It’s been the #1 question I’ve gotten as a storage Product Manager, and while I’ve long said that FCoE is not the panacea for the Data Center, I believe this goes a long way in making converged network even more realistic in today’s environments.

As the Product Manager for Fibre Channel over Ethernet (FCoE), I often get asked some of the hard questions about how the technology works. Sometimes I get asked the easy questions. Sometimes -- like two nights ago -- I get asked if the standards for FCoE are done.
I’m not kidding.
My own expectations for discussing FCoE were focused around the topics and conversations that we’ve been seeing over the last year, since the last Cisco Live in 2011. Read More »

My buddy Steve Foskett wrote a blog recently that talks about FCoE and 16Gb Fibre Channel. I want to say, for the record, that I like Steven, a lot, and normally I think he has a good grasp of the realities of new SAN technologies that emerge.
At the very least he has usually shown himself to be fair and balanced, even if not totally unbiased. In the many, many articles he has written I have never seen him knowingly write something to be untrue in his examination of technologies such as FCoE… until now.
For that reason, I can’t help but feel very disappointed. Read More »
