The Sun StorageTek 4Gb Fibre Channel (FC) Dual-Port ExpressModule (EM) HBA from Emulex consists of a single wide, EM bus expansion board that interfaces a 4-lane (8-lane physical) PCI Express (PCIe) bus to an FC optical media bus. The StorageTek EM HBA can act as either an initiator or a target. The board supports two independent FC buses operating at 4.25 Gbps. It is also backward compatible with 2.125 Gbps and 1.0625 Gbps devices. Small Form Factor (SFF) optical transceivers are used to connect to the external FC buses.
