    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


    Resolving the Confusion around DCB (I Hope)

    April 15th, 2013

    Storage traffic running over Ethernet-based networks has been around for as long as we have had Ethernet-based networks.  Of course sometimes it is technically not accurate to think of the protocols as fundamentally Ethernet protocols – whilst FCoE, by definition, only runs on Ethernet, iSCSI, SMB, and NFS,  they are, in reality, IP-based storage protocols …Read More


    How DCB Makes iSCSI Better

    March 5th, 2013

    A challenge with traditional iSCSI deployments is the non-deterministic nature of Ethernet networks. When Ethernet networks only carried non-storage traffic, lost data packets where not a big issue as they would get retransmitted. However; as we layered storage traffic over Ethernet, lost data packets became a “no no” as storage traffic is not as forgiving …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


    Will Ethernet storage move to 10GBASE-T?

    August 2nd, 2012

    10GBASE-T is a technology that runs 10Gb Ethernet over familiar Category 6/6a cables for distances up to 100m and is terminated by the ubiquitous RJ-45 jack. Till now, most datacenter copper cabling has been special Direct Attach cables for distances up to 7m terminated by an SFP+ connector. To work, data center switches need matching …Read More
