Dual-Port 16Gbps Fibre Channel HBA

The Emulex LPE31002-M6 is a dual-port host bus adapter built for 16Gbps Fibre Channel storage networks. It connects to the host system through a PCI Express 3.0 slot and presents two SFP+ transceiver cages for optical cabling. This adapter targets servers and workstations that need redundant, low-latency paths to enterprise storage arrays.

Thermals and power in normal operation

The card operates within standard PCIe slot power limits and relies on passive cooling through the server chassis airflow. No auxiliary power connector is required, and the design generates minimal acoustic noise because it has no onboard fan. Power draw scales with link utilisation across the two 16Gbps ports.

Build integration and cabling

Each port accepts an SFP+ transceiver, so the choice of fibre type and reach is decided at installation time. The half-height bracket fits 2U and taller rackmount servers without blocking adjacent slots. The adapter frees the system from proprietary storage interconnects by using the open Fibre Channel protocol over standard LC duplex cabling.

Questions about this item

How is the LPE31002-M6 installed in a PCIe 3.0 slot, and what step is often missed?

Insert the card into an x8 or x16 PCIe 3.0 slot, secure the bracket, then attach compatible SFP+ transceivers and fibre cables; the step often missed is installing the Emulex driver and management software before connecting to the SAN fabric.

What maintenance or replacement will the dual-port 16Gbps adapter need over time?

The SFP+ optical transceivers are the primary replaceable components; they can be swapped individually if a link degrades, while the adapter board itself has no user-serviceable parts and requires only occasional firmware updates from Broadcom.

What limit appears first when the 16Gbps Fibre Channel ports run sustained workloads?

The 16Gbps line-rate ceiling per port is the first bottleneck; aggregate throughput cannot exceed 32Gbps across both ports, and the PCIe 3.0 x8 host interface matches that bandwidth, so neither bus nor protocol overhead becomes the limiting factor first.
