PCIe2 LP 8 Gb 4-port Fibre Channel Adapter (FC EN0Y; CCIN EN0Y)
Learn about the specifications and operating system requirements for the feature code (FC) EN0Y adapter.
Overview
The PCIe2 LP 8 Gb 4-port Fibre Channel Adapter is a PCI Express (PCIe) generation-2, low-profile, high-performance, x8 short form factor plus (SFF+) Host Bus Adapter (HBA). This adapter enables multiple logical (virtual) connections to share the same physical port. Each logical connection has its own resources and the ability to be managed independently. Each port provides single initiator capability over a fiber link or provides multiple initiator capability with N_Port ID Virtualization (NPIV). The ports are connected by using mini little connectors (mini-LC) type connectors. These connectors use shortwave laser optics. The adapter operates at link speeds of 2, 4, and 8 gigabits per second (Gbps) and automatically negotiates to the highest speed possible. LEDs on each port provide information about the connection status and link speed of the port. The adapter connects to a Fibre Channel switch.
