Who Wins? The Benefits of Convergence to Ethernet for Storage Advances in Data Center Bridging and FCoE Improve Ethernet Performance for iSCSI and HPC Clusters

By IBM

Use of Ethernet as a switching fabric provides servers with a single connection and can greatly reduce the amount of equipment required in the data center. Companies with storage networks are switching from Fiber Channel to Ethernet-based storage solutions that use 10GbE. This trend is accelerating now with lossless DCB or Data Center Bridging Ethernet products such as IBM BNT RackSwitch G8124. With the adoption of the new DCB Ethernet protocols, Ethernet switching fabric can offer the technical features and the economic value necessary to become the switching fabric of choice for data center networking, storage and clustering.

    Nick,
    While IBM was an important player in the creation of FCoE and has a solid portfolio of solutions that supports FC, FCoE and Ethernet, convergence is much more than FCoE. HP and Cisco have taken a leadership position with switching solutions that can do FC or Ethernet and change between these options – see my write-up about HP flex ports and Cisco unified ports: http://wikibon.org/wiki/v/FCoE_sales_steadily_growing_as_Juniper_and_HP,_not_Brocade,_compete_with_Cisco
    Customer adoption of FCoE has been led in the embedded space (which IBM offers a few solutions although in recent reports, it is HP and Cisco that seem to be selling more of the converged options. Giving customers options that can support the legacy (FC) and new (FCoE and other Ethernet options) looks to be a smart bet as there is hesitance in the storage community to jump full into FCoE. Hopefully the BNT solutions catch up or IBM partners to deliver similar solutions.

    I agree Stu, but leave out Brocade, Dell with F10 and Mellanox’s new ToR switch. This area is heating up and 2012 promises to be a year of converged I/O experimentation.

    Cisco is the only one with an end-to-end FCoE solution with the server, the adapter, the credible switches and through the VCE joint venture, the target storage with EMC integrated with VMware. They offer “one throat to choke”if anything goes wrong. Users who really want to go to converged fabrics are self selecting, and from what I see, they are choosing Cisco. Still small numbers though.
