  • Qualified for SR630 SR650 SR850 SR860 SR950 and SD530 platforms

32 Gb Fibre Channel Adapter for ThinkSystem Servers

This single-port host bus adapter delivers 32 Gbit/s Fibre Channel connectivity over a PCI Express 3.0 x8 slot. It is designed for Lenovo ThinkSystem servers that require high-throughput storage networking. The card targets environments running all-flash arrays where low latency and high IOPS are critical.

SFP+ Connector and Plug-In Card Format

The adapter uses a standard SFP+ transceiver interface, allowing fibre type and reach to be chosen per link. Its plug-in card form factor fits the compatible ThinkSystem chassis listed in the specifications. Installation follows normal PCIe card procedures without specialised mounting hardware.

Hardware Offload Reduces CPU Load

Full hardware offloads move protocol processing off the host CPU, helping sustain up to 1.3 million IOPS with minimal processor overhead. The Gen 6 Fibre Channel engine is built on Cavium technology for efficient data movement. Power draw and thermal output remain proportional to the single-port 32 Gbps workload.

Questions about this item

What PCIe generation and lane width does the QLE2740 use, and what throughput ceiling does that impose?

The adapter uses a PCI Express 3.0 x8 host interface, which caps practical throughput at the bus's 32 Gbit/s data transfer rate.

What physical slot and chassis space does this plug-in card require?

It is a plug-in card that fits a PCIe x8 or wider slot and needs a standard full-height bracket opening.

How is the SFP+ transceiver seated, and what step do installers often miss?

Insert the transceiver until it clicks, then remove the dust plugs and connect the fibre cables; the click is the step most often missed.
