QLogic Corp. QLE2564-CK expansion card

SKU CH-25SH-0F6SQ MPN QLE2564-CK

Four-port Fibre Channel controller card with 8 Gbps connectivity via PCI Express

  • TypeController Card
  • Quad-port design enables four simultaneous 8 Gb Fibre Channel connections
  • PCI Express interface provides direct host-bus connectivity
  • QLogic SANblade architecture delivers hardware-based Fibre Channel offload
  • Four ports reduce slot count for multi-path storage deployments
  • New condition ensures full manufacturer specification compliance

QLogic SANblade Quad-Port HBA

The QLogic QLE2564-CK is a four-port Fibre Channel host bus adapter designed for servers and workstations that connect to 8 Gb storage area networks. It suits IT teams building or expanding SAN infrastructure with multiple fabric paths.

PCIe slot and 8 Gb link constraints

Each port operates at up to 8 Gb/s, so aggregate throughput is bounded by the host bus generation and lane count installed in the server. Cable reach and switch port speeds must also match the 8 Gb standard to avoid bottlenecks.

Four independent 8 Gb Fibre Channel ports

The card presents four physical FC ports on a single bracket, enabling multipath configurations or connection to separate fabrics. Systems needing fewer ports or a different link speed should select an alternative adapter.

Questions about this item

What does the four-port design mean for my SAN connectivity?

The card provides four independent Fibre Channel ports, allowing multiple host connections or multipath configurations from a single PCIe slot.

How does the 8 Gb Fibre Channel speed perform inside a server?

Each port operates at 8 Gb line rate, so sustained throughput depends on the switch fabric and storage target rather than the card alone.

Which PCIe generation does the QLE2564-CK use and what bandwidth does that provide?

The adapter uses a PCIe interface compatible with the slot it is installed in; actual bandwidth is determined by the server's PCIe generation and lane width.
