Dual-Channel 4 Gbit/s Fibre Channel Adapter

The HPE StorageWorks FC1242SR is a half-height PCI Express host bus adapter with two LC ports for multi-mode optical fibre. It targets ProLiant servers that need direct connectivity to HPE StorageWorks arrays at 4, 2 or 1 Gbit/s speeds. The card fits standard low-profile slots and presents a green PCB.

Replaces Single-Channel or Slower HBAs

This adapter upgrades servers limited to one fibre link or to 2 Gbit/s throughput, doubling path redundancy and headroom for storage traffic. The jump is worth it when applications demand simultaneous access to multiple LUNs or when array firmware requires dual-path failover. It does not serve builds needing copper media or 8 Gbit/s and above.

Sustained Load Behaviour

Under continuous I/O the dual-channel design balances queue depth across both ports, preventing a single saturated link from stalling the host. Class 2 and Class 3 frame handling keeps fabric acknowledgements flowing without host CPU intervention. The half-height form factor limits airflow compared with full-height cards, so chassis cooling must handle the thermal load.

Questions about this item

Will this half-height HBA fit a 2.5-inch-wide low-profile PCIe slot?

The card measures 6.6 inches long by 2.5 inches wide and is a half-height design, so it fits standard low-profile PCIe slots that accept those dimensions.

How do I install the dual LC optical cables without damaging the transceiver ends?

Remove the dust caps, align each LC connector with its port on the bracket, and push straight in until the latch clicks; forcing at an angle can crack the ferrule.

When should the SFP transceivers be replaced in this FC1242SR adapter?

Replace the SFP modules if link errors rise, the optical power budget drops below spec, or a port fails to establish a 4 Gbit/s, 2 Gbit/s or 1 Gbit/s connection.
