HPE 649283-B21 10Gb Dual Port 544FLR-QSFP Adapter

SKU CH-PEEY-TTB8R

Dual-port 10 Gb Ethernet adapter with QSFP slots for optical fibre, PCI Express 3.0 x8 host interface, and ConnectX-3 architecture supporting InfiniBand up to 56 Gb/s

  • Product type10Gigabit Ethernet Card
  • Dual-port 10Gb Ethernet for high-throughput server connectivity
  • ConnectX-3 architecture delivers InfiniBand bandwidth up to 56 Gb/s and Ethernet up to 40 Gb/s
  • PCI Express 3.0 x8 host interface provides low-latency data paths
  • Hardware-based QoS and congestion control maximise effective network bandwidth
  • QSFP optical-fibre slots support flexible 10, 20 or 40 Gb/s Ethernet links

Dual-port 10Gb server adapter

The HPE 649283-B21 544FLR-QSFP adapter adds two 10Gb Ethernet ports to select ProLiant SL, DL and ML servers through a PCI Express 3.0 x8 slot. It targets administrators who need low-latency 10Gb connectivity for financial-services or high-performance workloads.

Sustained throughput with QoS

Hardware-based traffic segregation and congestion control maintain effective bandwidth during continuous load rather than only in short bursts. The ConnectX-3 architecture supports Ethernet rates of 10, 20 or 40 Gb/s and InfiniBand up to 56 Gb/s FDR for consistent data flow.

Plug-in card with QSFP cages

The plug-in form factor weighs approximately 1 lb and accepts optical-fibre QSFP transceivers for flexible media choices. Dual ports allow link aggregation or separate fabrics without occupying additional expansion slots in the chassis.

Questions about this item

How much heat does the 544FLR-QSFP adapter add when running 10 Gb Ethernet links all day?

The card is designed with low power requirements, so its thermal contribution stays modest even under continuous 10, 20 or 40 Gb/s Ethernet loads.

Which server slot and transceiver type must I already have to install the 649283-B21?

You need a free PCI Express 3.0 x8 slot and QSFP-compatible optical-fibre transceivers for each of the two ports.

Will the 544FLR-QSFP work in an older ProLiant DL chassis that only has PCIe 2.0 backplanes?

The adapter uses a PCI Express 3.0 x8 host interface; it will negotiate down to 2.0 speeds if the chassis only provides that generation.
