Dual-port 8Gbps Fibre Channel HBA

The QLogic QLE2562Product is a PCI Express x8 host bus adapter with two LC connectors for multi-mode optical fibre. It targets enterprise data centres that need dual-path connectivity to storage area networks at 8Gbit/s line rate.

Practical limits of 8Gbps Fibre Channel

The 8Gbit/s interface supports point-to-point and switched-fabric topologies using Fibre Channel Class 2 and Class 3 service. Multi-mode fibre restricts link distance compared with single-mode, so runs beyond a few hundred metres will require different optics. Bandwidth is shared across both ports, so simultaneous heavy loads on each port can saturate the PCIe x8 host link.

Low-profile installation notes

The card measures 2.5 inches high by 6.6 inches wide and fits low-profile brackets, but the dual LC ports protrude slightly and can catch on adjacent slot covers. Firmware must match the switch fabric; mismatched versions are the most common cause of link failures during first boot.

Questions about this item

Should I choose the single-port or dual-port 8Gbps version?

This model provides two LC ports so both fabric connections are available from one card.

What does the 8 Gbit/s rate deliver inside a server?

Each port runs at up to 8 Gbit/s over multi-mode fibre using the PCI Express x8 host link.

How does the PCI Express x8 interface limit real-world throughput?

The x8 host interface supplies enough bandwidth for both 8 Gbit/s ports to operate at line rate simultaneously.
