Oracle's Sun Storage 16 Gb FC PCIe Universal HBA (Emulex) is a class of adapter that provides PCI selectable 16 Gb Fiber Channel (FC) or 10 GbE Fiber Channel over Ethernet (FCoE) connectivity - meeting today's and tomorrow's connectivity needs while preserving IT investments. Changing fabric personalities is seamless via smart detection of SFP+ optical transceivers. Depending on which optical transceiver is installed, the HBA will intelligently know to run in FC or FCoE mode. In an Ethernet environment the adapter provides full Ethernet (NIC) connectivity concurrently with FCoE.
