Yesterday I posted about Cisco UCS supporting RDMA (SMB Direct) with firmware version 2.2(4b)B. Walter Dey, former Cisco Distinguished Engineer at Cisco informed me not only about the RDMA feature he also showed me that Cisco UCS now supports Consistent Device Naming which was introduced with Windows Server 2012. Consistent Device Naming (CDN) allows Ethernet interfaces to be named in a consistent manner. This makes Ethernet interface names more persistent when adapter or other configuration changes are made. To use CDN in Cisco UCS you need to run firmware version 2.2(4b)B. This will help to make it a lot easier to identify network interfaces used with Windows Server 2012 R2 and Hyper-V.

    Hi Thomas,

    Thank you for the update, however do you know if this will be also applicable to non=LOM NICs?
    I’m asking because on UCSC-C220-M3S servers with bios version of 2.0.3.0 this was enabled only for LOM (on-board NICs).
    I haven’t applied this bios version yet to know if it changes the behavior, could you check and tell us please?

    Regards,

    George Simos
