Graviton QLE2562-CK 2562 network card

Two-port 8 Gbps Fibre Channel HBA

This dual-port host bus adapter connects servers to Fibre Channel storage networks at 8 Gbps per port. Short-range SFP+ optics are included for multimode fibre links. The card targets datacentre administrators who need reliable block-level storage connectivity over a PCI Express slot.

Installation notes and common issues

The adapter fits a standard PCIe slot and uses the in-box SR transceivers; no extra cabling is required beyond duplex multimode fibre. Driver support varies by operating system, so verify the vendor driver matrix before deployment. The low-profile bracket may not match full-height chassis without a separate bracket kit. Incorrect fibre polarity or mismatched link speed on the switch side are the most frequent causes of link failures.
