ATTO single-port Fibre Channel card PCIe 3.0 x8 LC connector

ATTO Technology

ATTO Technology CTFC-321P-000 Fibre Channel expansion card 32 Gbit/s PCIe 3.0 x8

SKU CH-4MF4-CBXYQ MPN CTFC-321P-000

Single-channel 32 Gbit/s Fibre Channel card with one LC port, PCIe 3.0 x8, delivering up to 3200 MB/s throughput

  • Single-channel 32 Gbit/s Fibre Channel throughput
  • PCIe 3.0 x8 interface for broad server compatibility
  • LC SFP port enables flexible fibre cabling
  • Up to 3200 MB/s bandwidth in one slot
  • Gen 7 Fibre Channel with PCIe 4.0 interconnect

ATTO 32 Gbit/s Fibre Channel HBA

The ATTO Celerity FC-321P is a single-channel Fibre Channel host bus adapter built for enterprise storage networks. It connects to a PCIe 3.0 x8 slot and delivers 32 Gbit/s throughput for high-performance data infrastructures. System integrators and OEMs use it to add Gen 7 Fibre Channel connectivity to servers and workstations.

Single LC port with SFP flexibility

The card ships with one LC Fibre Channel port that accepts an SFP transceiver, letting you choose the optics that match your cabling distance and fibre type. This single-port design occupies only one expansion slot while providing up to 3200 MB/s of bandwidth for storage traffic.

Verify PCIe slot generation and fibre cabling

Confirm your motherboard or riser provides a physical x8 slot wired for PCIe 3.0 or newer to avoid bandwidth limits. Ensure you have compatible LC duplex fibre patch cables and a 32 Gbit/s SFP transceiver, as neither is included with the adapter.

Questions about this item

Does the single LC port or SFP transceiver need periodic replacement under heavy Fibre Channel traffic?

The card uses a standard LC connector and SFP transceiver; the transceiver is a field-replaceable module, so only the SFP would be swapped if link budgets change or a port fails.

What throughput ceiling appears first when the host bus adapter runs at sustained 32 Gbit/s line rate?

The PCIe 3.0 x8 host interface caps at about 3200 MB/s, so the bus becomes the bottleneck before the 32 Gbit/s Fibre Channel link saturates.

How much power does the adapter draw and how hot does it get when running all day in a closed chassis?

The single-channel Gen 7 HBA is a low-profile plug-in card with no onboard fan; typical power draw stays within the PCIe slot limit and it relies on system airflow for cooling.
