Low-profile plug-in card with two SFP+ ports

QLogic Corp.

QLogic Corp. QLE2742-SR-CK 2700 Series 2x 32Gb Fiber Channel SFP+ Host bus adapter

SKU CH-4GKW-2R590 MPN QLE2742-SR-CK

A dual-port 32 Gbps Fibre Channel host bus adapter from the 2700 series supporting 623 ft links and 2048 concurrent logins

  • Dual-port 32 Gbps throughput for high-bandwidth storage fabrics
  • 623 ft reach extends connectivity across data-centre aisles
  • 2048 concurrent logins and exchanges support dense virtualised workloads
  • Low-profile plug-in card fits space-constrained servers
  • 2700 series Gen 6 Fibre Channel delivers 32 Gbps line-rate performance

Dual 32 Gbps Fibre Channel adapter

The QLogic 2700 Series QLE2742-SR-CK is a dual-port host bus adapter built for servers that need 32 Gbps Fibre Channel connectivity. It targets IT teams running storage-area networks where consistent throughput and low latency matter. The card plugs into a low-profile PCIe slot and supports concurrent logins and active exchanges of 2048 each.

Low-profile plug-in card with SFP+ ports

A low-profile bracket lets the adapter fit in 1U or space-constrained chassis without blocking adjacent slots. Two SFP+ cages accept 32 Gbps optical transceivers for links up to 623 ft over multimode fibre. Wired connectivity uses the FC-GS-2, FC-GS-3, FCP-2, FC-PI-5, FC-PI-6, FC-Tape and SCSI-FCP protocol stack for broad fabric compatibility.

Passive cooling suits dense racks

With no onboard fan the card relies on chassis airflow, keeping acoustic output negligible in crowded rack rows. Power draw stays within the PCIe slot envelope, so no auxiliary connector is required. The 2700 Series controller manages 32 Gbps line rate without thermal throttling under sustained I/O loads.

Questions about this item

What does the 32 Gbps Fibre Channel interface cap in practice?

The dual 32 Gbps ports support up to 623 ft per link and handle 2048 concurrent logins and 2048 active exchanges on the 2700 series adapter.

What slot and bracket does the QLE2742-SR-CK need to fit?

It uses a low-profile plug-in card form factor, so it fits a standard PCIe slot with a low-profile bracket.

How is the card installed, and what step is often missed?

Insert the low-profile card into a PCIe slot, secure the bracket, then connect SFP+ transceivers and fibre cables to the two 32 Gbps ports.
