Hello Dan,  MEM has nothing to do with the NICs themselves.  It manages the iSCSI sessions and provides an enhanced MPIO schema with EQL arrays.  especially with Multimember pools.   it will work with Broadcoms, with or without iSCSI offload enabled,  Intel NICs, HP branded NICs, etc...   As long as ESX supports it as a nic and you have properly configured iSCSI MEM will work.    If you are all familiar with the MPIO DSM that we include with the Windows HIT kit, that is what MEM does for ESX.    Regards,    Don 
So I have a bunch of R610 servers and I do not have the Broadcom NetXtreme II NICs. Does it still make sense for me to still install and enable the EqualLogic Multipathing Extension Module? I currently have two EqualLogic arrays and will be expanding to a 3rd in the near future (just need to unbox it). Current NICs in my servers are: Broadcom BCM5709Intel 82576Intel 82571EB Thank youDan
