What is the preferred (best practice) way to maintain current levels of HBA Drivers & Firmware? Some are EMC rebranded Emulex HBA cards -- Would that mean to use EMC's website as the source or Emulex as the source which would be equivalent? For example,  EMC LPe12002-E 8Gb 2-port PCIe Fibre Channel Adapter. Also, there is the other component, the fabric array, would it dictate a cross-reference in determining  the HBA driver & firmware version can be applied?
