Universal HBA Overview
Oracle's Sun Storage 16 Gb FC PCIe Universal HBA, Emulex (marketing part number 7101684) is a standalone, PCIe low-profile universal host bus adapter. The HBA is considered universal because it is a configurable board that changes its operating protocol mode from a two-port 16 Gb FC HBA to a two-port 10 GbE CNA, based on the optical transcievers and optical cables that you insert and attach to the HBA.
The board interfaces an eight-lane PCI Express bus, with eight lanes supporting two Fibre Channel (FC) or two Fibre Channel over Ethernet (FCoE) optical media ports. Each independent FC port operates at 16 Gb/sec and features 16/8/4 autonegotiation. Each FCoE port operates at 10 Gb/sec. You can configure the following three options:
-
10 GbE FCoE option—The version of the card that provides twin-ax (or, copper) 10 GbE FCoE ExpressModule Converged Network Adapter functionality. No optic modules are installed in this Converged Network Adapter.
-
16 Gb FC optics option—The version of the card that has 16 Gb FC optics installed (optics marketing part number: 7101686) in the SFP+ connecter of the card, providing short-wave 16 Gb Fibre Channel ExpressModule Host Bus Adapter functionality.
-
10 GbE FCoE optics option—The version of the card that has 10 GbE optics installed (optics marketing part number: 7101688) in the SFP+ connector of the card, providing short-range 10 GbE FCoE ExpressModule Converged Network Adapter functionality.
