SKU CH-75EY-13JD1 MPN 81QProduct

A single-port 8 Gbit/s Fibre Channel host bus adapter with a PCI Express 2.0 x8 interface in a low-profile plug-in card form factor

  • Product typeFibre Channel Host Bus Adapter
  • 8 Gbit/s throughput for fast storage access
  • Single LC port connects directly to SAN fabrics
  • PCI Express 2.0 x8 host interface fits modern servers
  • Low-profile plug-in card suits space-constrained chassis
  • RoHS certified for environmentally responsible deployment

Single-Port 8 Gbit/s Fibre Channel Adapter

The HPE StorageWorks 81Q is a low-profile plug-in card that adds one 8 Gbit/s Fibre Channel port to a server. It targets administrators who need a direct host-bus connection to an existing SAN fabric. The card uses a PCI Express 2.0 x8 host interface and ships in new condition.

PCI Express 2.0 x8 Host Interface Limit

The adapter connects through a PCI Express 2.0 x8 slot, so throughput cannot exceed the bandwidth that generation and lane width provide. Systems limited to PCI Express 1.x or to fewer than eight lanes will reduce the effective data rate. No other host-bus technology is supported on this card.

One LC Port at 8 Gbit/s

The card presents a single LC optical port rated for 8 Gbit/s Fibre Channel traffic. Environments that require multiple independent fabric connections or higher link speeds will need additional or different adapters. RoHS compliance confirms the assembly meets restricted-substance requirements.

Questions about this item

What does the single LC port on the 81Q adapter mean for my cabling?

The card provides one LC duplex connector, so a single fibre patch cord is all that is needed to link the host to the SAN fabric.

How does the 8 Gbit/s transfer rate perform once the card is installed in a server?

The adapter delivers up to 8 Gbit/s line-speed Fibre Channel throughput over the PCI Express 2.0 x8 host interface.

What does the PCI Express 2.0 x8 host interface cap in practice?

The x8 lane width on PCI Express 2.0 provides enough bandwidth to sustain the full 8 Gbit/s Fibre Channel rate without host-bus bottlenecks.
