Dual-Port 10GbE Adapter for Virtualised Servers

This IBM Emulex Virtual Fabric Adapter adds two 10Gbps Ethernet ports through a PCI Express 2.0 x8 slot. It targets data-centre servers that run multiple virtual machines and need converged network and storage traffic on a single card. The dual-port design provides link redundancy or bandwidth aggregation for heavy east-west traffic. Factory-sealed condition ensures clean inventory for deployment.

Low-Power Operation in Dense Racks

The adapter is built for performance per watt, lowering the power and cooling budget in dense rack environments. Storage protocol offloads move processing off the host CPU, reducing overall system heat during sustained loads. With no active cooling specifications disclosed, the card relies on server chassis airflow for thermal management. Typical noise contribution is negligible inside managed server fans.

Upgrade from Single-Port or 1GbE NICs

This card replaces single-port 10GbE or dual-port 1GbE adapters when virtual machine density demands more throughput and offload capability. The jump is worth it when CPU cycles spent on protocol handling become a bottleneck or when cabling flexibility between fibre and twin-ax copper is required. Servers limited to PCI Express 2.0 x8 slots gain full advertised speed without platform changes.

Questions about this item

How do I install this PCI Express 2.0 x8 adapter correctly?

Insert the card into a PCIe 2.0 x8 or wider slot, secure the bracket screw, attach the SFP+ modules, then connect fiber or twin-ax cables to the dual ports before powering on the server.

What maintenance will the Emulex Virtual Fabric Adapter need over time?

Periodically reseat the SFP+ transceivers, clean the fiber end-faces with a lint-free wipe, and verify link LEDs remain solid green during scheduled server maintenance windows.

What limit appears first when the dual 10GbE ports run sustained traffic?

The PCI Express 2.0 x8 host interface caps combined throughput at the bus maximum, so sustained line-rate on both ports simultaneously will saturate the upstream link first.
