These are the release notes for the Emulex FC/FCoE ESX driver.

VMware will officially support 16G FC HBA in MN.next in a limited configuration, with FC HBA and switch at 16G connecting to two 8G storage arrays. End to end 16G FC support targets OP release. VMware will provide equivalent certification program at MN.next and OP aligning with ESXi platform feature.

In ESXi 50 and updates releases, partners can certify FC HBA at 8G, and VMware only supports configuring the HBA at 8G or lower speed.

Instructions on how to set link speed to 8G:

1.  Install Emulex core kit and/or CIM provider.
2.  For ESX 4.0 and 4.1 - run hbacmd setdriverparam lpfc_link_speed 8
3.  For ESXi 4.0, 4.1, and 5.0 - run remote GUI OCM and change driver param link speed.
