    2013 in Review and the Outlook for 2014 – A SNIA ESF Perspective

    January 28th, 2014

    Technology continues to advance rapidly. Making sense of it all can be a challenge. At the SNIA Ethernet Storage Forum, we focus on storage technologies and solutions enabled by and associated with Ethernet Networks. Last year, we modified the charters of our two Special Interest Groups (SIG) to address topics about file protocols and storage …Read More


    Fibre Channel over Ethernet (FCoE): Hype vs. Reality

    January 7th, 2014

    It’s been a bit of a bumpy ride for FCoE, which started out with more promise than it was able to deliver. In theory, the benefits of a single converged LAN/SAN network are fairly easy to see. The problem was, as is often the case with new technology, that most of the theoretical benefit was …Read More


    Software Defined Networks for SANs?

    September 26th, 2013

    Previously, I’ve blogged about the VN2VN (virtual node to virtual node) technology coming with the new T11-FC-BB6 specification. In a nutshell, VN2VN enables an “all Ethernet” FCoE network, eliminating the requirement for an expensive Fibre Channel Forwarding (FCF) enabled switch. VN2VN dramatically lowers the barrier of entry for deploying FCoE. Host software is available to …Read More


    Q&A Summary from the SNIA-ESF Webcast – “How VN2VN Will Help Accelerate Adoption of FCoE”

    August 29th, 2013

    Our VN2VN Webcast last week was extremely well received. The audience was big and highly engaged. Here is a summary of the questions attendees asked and answers from my colleague, Joe White, and me. If you missed the Webcast, it’s now available on demand. Question #1: We are an extremely large FC shop with well …Read More


    Ethernet is the right fit for the Software Defined Data Center

    August 12th, 2013

    “Software Defined” is a label being used to define advances in network and storage virtualization and promises to greatly improve infrastructure management and accelerate business agility. Network virtualization itself isn’t a new concept and has been around in various forms for some time (think vLANs). But, the commercialization of server virtualization seems to have paved the path …Read More


    10 Gigabit Ethernet – 2H12 Results and 2013 Outlook

    April 18th, 2013

    Seamus Crehan, President, Crehan Research Inc. 2H12 results 2012 turned out be another very strong growth year for 10 Gigabit Ethernet (10GbE), with the data center switch market and the server-class adapter and LAN-on-Motherboard (LOM) market both growing more than 50%.  Broad long-term trends such as virtualization, convergence, data center network traffic growth, cloud deployments, …Read More


    VN2VN: “Ethernet Only” Fibre Channel over Ethernet (FCoE) Is Coming

    February 26th, 2013

    The completion of a specification for FCoE (T11 FC-BB-5, 2009) held great promise for unifying storage and LAN over a unified Ethernet network, and now we are seeing the benefits. With FCoE, Fibre Channel protocol frames are encapsulated in Ethernet packets. To achieve the high reliability and “lossless” characteristics of Fibre Channel, Ethernet itself has …Read More


    What Up with DCBX?

    January 31st, 2013

    I guess this is a blog that could either be very short or very long… The full name of the protocol – Data Center Bridging capability eXchange (DCBX) basically tells you all you need to know or maybe nothing at all. At its simplest, DCBX does what it says on the tin and the way …Read More


    How is 10GBASE-T Being Adopted and Deployed?

    January 8th, 2013

    For nearly a decade, the primary deployment of 10 Gigabit Ethernet (10GbE) has been using network interface cards (NICs) supporting enhanced Small Form-Factor Pluggable (SFP+) transceivers. The predominant transceivers for 10GbE are Direct Attach (DA) copper, short range optical (10GBASE-SR), and long-range optical (10GBASE-LR). The Direct Attach copper option is the least expensive of the …Read More


    Ethernet Storage Forum – 2012 Year in Review and What to Expect in 2013

    December 20th, 2012

    As we come to a close of the year 2012, I want to share some of our successes and briefly highlight some new changes for 2013. Calendar year 2012 has been eventful and the SNIA-ESF has been busy. Here are some of our accomplishments: 10GbE – With virtualization and network convergence, as well as the …Read More
