    Broadcom BMC57810 10g with ESX 4.1u3

      Ryan Troy (Ryan Troy) asked that I share this in case someone happens to run into it.


      I had a scenario with a customer using brand new supermicro servers with Broadcom BMC57810 10g nics. They were having network performance issues to the point the interfaces were only performing around 10-30mb/s.  The issue ended up being old bnx2 drivers (version 1.72.54.v41.1) present in ESX 4.1u3, I'm not sure if this applies to ESXi 5.x they didn't have a server to test on. The customer updated the drivers to (1.74.22.v41.1) and the performance is now normal.


      Drivers as of 1/13/2013 can be found here.



      In ESX 4.1 you can find the driver version by running these commands via the CLI.


      Grab the nic device name

      #esxcfg-nics -l
