QLogic Corp. QLE2690Product 16Gb Fibre Channel HBA network card

SKU CH-MH9S-PTD4R MPN QLE2690Product

A 16 Gb Fibre Channel host bus adapter delivering up to 650K IOPS with low CPU overhead

  • 16 Gb Fibre Channel speed for high-throughput storage networking
  • Up to 650 K IOPS per port with low CPU utilisation
  • Full hardware offloads reduce host processing overhead
  • QLogic StorFusion technology provides QoS and resiliency
  • Single-port Enhanced Gen 5 HBA model QLE2690-SR-CK

16Gb Fibre Channel HBA for Enterprise Storage

The QLogic QLE2690Product is a single-port Enhanced Gen 5 Fibre Channel Host Bus Adapter delivering 16Gb connectivity. It targets IT organisations that require reliable, high-throughput storage networking for virtualised workloads and demanding database environments. The adapter provides full hardware offloads to keep CPU utilisation extremely low while sustaining up to 650K IOPS per port. Buyers needing multi-port density should consider the dual-port QLE2692 variant instead.

PCIe installation with driver and firmware

The card installs into a standard PCI Express slot and is recognised by major operating systems once the appropriate QLogic drivers are loaded. Common issues arise when firmware on the adapter or the connected switch is outdated, leading to link negotiation failures or reduced throughput. Verify that the HBA firmware matches the switch vendor’s supported matrix before deploying in production. A clean driver installation prevents intermittent disconnects during heavy I/O loads.

Confirm switch compatibility

Ensure your Fibre Channel switch supports 16Gb Enhanced Gen 5 speeds and that the required SFP+ transceivers match the optical or copper media in use. Check that the server chassis has an available PCIe slot with sufficient lane width for the adapter’s performance envelope. Validate that your storage array presents LUNs compatible with the HBA’s feature set, including StorFusion QoS capabilities. Without a matching 16Gb fabric the adapter will negotiate down to a lower speed.

Questions about this item

How can I confirm the QLE2690 is delivering the stated 650K IOPS after installation?

Use the QLogic management tools to monitor live port statistics; the dashboard reports real-time IOPS, latency and error counters so you can verify the adapter is hitting the 650K IOPS target.

What ships with the QLE2690-SR-CK and what must I source separately?

The box contains the single-port 16Gb HBA with a short-range optical transceiver already fitted; you only need to add LC duplex fibre patch cables that match your switch and storage port types.

Should I choose the QLE2690 or the QLE2692 for a single-path connection?

Select the QLE2690 when you need one 16Gb port; the QLE2692 is the dual-port variant and adds a second port you would not use in a single-path design.
