QLogic QLE2742
Dual‑Port 32Gb Gen6 Fibre Channel HBA, PCI‑E 3.1 x8 SFP+ Host Bus Adapter
Product Overview
The QLE2742 is Marvell QLogic Gen6 32Gb Fibre Channel dual‑port host bus adapter (HBA), built for enterprise SAN storage environments. Delivering industry‑leading low‑latency storage connectivity, it supports FC‑NVMe and traditional SCSI‑FCP workloads. Full‑hardware offload reduces CPU overhead significantly. Backward compatible with 16Gb /8Gb Fibre‑Channel fabrics, it protects existing SAN infrastructure investment. Widely available aftermarket as new‑surplus, refurbished and server‑pull used units.
