About the 4XX7A09941
4XX7A09941 is Lenovo's single-port Gen 6 32Gb Fibre Channel host bus adapter for ThinkSystem servers, built on the Marvell QLogic QLE2740 ASIC. Designed for virtualized enterprise computing and high-I/O database engines, it delivers 650,000 IOPS and line-rate 32Gb/s throughput with minimal host CPU overhead. It provides complete hardware support for concurrent FC-NVMe and traditional FCP-SCSI protocols.
Compatibility
Supported across ThinkSystem rack servers including SR650, SR650 V2, SR630, SR630 V2, SR645, and SR665. Fits into any standard PCIe 3.0 or 4.0 x8 or x16 slot with either low-profile or full-height bracket. Operates with Brocade and Cisco Fibre Channel fabrics and auto-negotiates down to 16Gb and 8Gb speeds with legacy storage arrays.
How to identify a genuine unit
The card features a compact low-profile PCB with one SFP+ optical port and a black passive heatsink covering the QLogic controller. Lenovo option part number 4XX7A09941, FRU part number 4XC7A08223 (or 02JG103), and feature code AYCT appear on the barcode label. Operating system utilities report vendor ID 1077 (QLogic) and Lenovo subsystem ID 17AA.
Buying used
Inspect the SFP+ port cage for intact optical latch springs and clean electrical contact pins. Confirm that the card comes with the appropriate bracket for your chassis height. Verify that the card enters the QLogic Fast!UTIL setup utility during system boot and that firmware can be updated cleanly using Lenovo XCC or OneCLI tools.
