Four-port 16 Gbit/s Fibre Channel HBA

The QLogic QLE2694-SR-CK is a full-height plug-in card that adds four LC multi-mode ports to a server or workstation. It connects through a PCI Express 3.0 x8 slot and delivers 16 Gbit/s per port for storage-area-network traffic. The adapter suits IT teams expanding fibre connectivity in existing 2U or larger rack systems.

Multi-mode LC connectivity

Four on-board LC transceivers ship with the card, removing the need to source separate optics for short-range fibre runs. The board carries WEEE certification, confirming it meets EU electronic-waste directives. A three-year limited warranty from the manufacturer covers the adapter itself.

16 Gbit/s per port with PCIe 3.0 x8 headroom

Each of the four ports runs at 16 Gbit/s, giving aggregate throughput that matches typical flash-array front-end links. The x8 electrical interface provides enough lane bandwidth to keep all ports saturated under normal SAN workloads. Very high queue-depth or all-flash scale-out clusters may eventually exceed the bus capacity.

Questions about this item

What maintenance or replacement will the 4-port 16Gb Fibre Channel HBA need later?

The card has no user-serviceable parts; the LC transceivers are fixed, so only a full card swap is possible if a port fails.

Which limit appears first when the PCIe 3.0 x8 host interface runs all four ports at 16Gb/s?

The x8 lane width caps aggregate throughput at the PCIe 3.0 x8 maximum, so the bus saturates before the four 16Gb Fibre Channel links do.

How much noise and heat does the full-height 4.4" by 6.6" plug-in card produce during continuous operation?

The adapter is passively cooled with no fan, so it adds no audible noise; heat output is limited to the ASIC and transceiver dissipation under load.
