The ARC Series D-Class Network Adapters

The Myricom ARC Series D-Class Network Adapter
A Low-cost, Low-latency Financial Trading Interface.


The D-Class is financial trading’s lowest cost full function 10 GbE network adapter. With DBL, a tightly integrated combination of FPGA firmware and software, the D-Class drives down system-level Tick-To-Trade latency and enables advanced financial trading capabilities.

With Sniffer10G firmware and software, the D-Class provides a cost-effective packet capture option..
Unique application-enhancing features include extremely accurate timestamping on both RECEIVE and SEND packets


Bus Interface PCI Express Gen 3, 8 lanes wide
Form Factor Low-profile PCI Express x8 ships with a standard height faceplate installed and low-profile faceplate in the box. Optional timing kit has a standard height faceplate with coax connectors installed.
Electrical Power 25 watts or less for all ARC Series models
Environmental It is recommended that D-Class adapters be installed into servers that provide some air flow over the PCIe slots (very common). Use in an office or computer room environment.
Passive Copper Cable Length 7 meters with a quality, passive, copper cable. Not all passive cable specifications support this length.
Operating Systems Support for all major Linux distributions as well as Windows 2008R2 and newer.
Connections Dual SFP+ 10GbE ports

General Operating Capabilities

Packets Per Second Every adapter optimized for ultra-low latency will bump into a maximum packet-per-second rate when the packets hit Intel’s PCIe implementation. That maximum depends on the Intel chip at the other end of the PCIe bus. Expect about 22 M PPS.
On-board clock tick precision The process associating timestamps with packets has ±5 nanoseconds of uncertainty. If you elect to synchronize with an external time source (“trim the clock”), that process has ±10 nanoseconds of uncertainty.
Timestamp Stability Timestamp stability is determined by the on-board oscillator (a Vectron VT 804 TCXO) or by an external 10 MHz clock connected via an optional timing kit.
IEEE 1588 Time stamps are captured in a manner that allows IEEE 1588 software implementations to deliver highly accurate, synchronized time.
Virtualization The D-Class adapter is compatible with all popular virtual environments, provided that users assign the adapter to a single virtual machine. The alternative, sharing an adapter, conflicts with delivering high performance.

Financial Trading Capabilities

Financial Trading Firmware and Software Support The DBL combination of tightly integrated FPGA firmware and software drives down Tick-To-Trade latency at multiple points in the trading process, allowing applications to deliver higher fill rates. It moves packets into the host computer with the lowest possible latency, then sends those packets directly to specific CPU cores, bypassing the kernel entirely. It also stages TCP market orders or quotes in advance to further reduce latency.
DBL End Points Support for 32 simultaneous rings (DBL endpoints). The size of each ring is limited by the amount of host memory available. Support of up to 511 simultaneous UDP multicast groups open per Ethernet port (1022 per board).

Packet Capture Capabilities

Throughput Sniffer10G provides 100% lossless packet capture and injection for all Ethernet packet sizes. Supports the maximum possible 10G packet rate of 14.8 million packets per second.on each 10 GbE line.
Packet Capture Firmware and Software Support The Sniffer10G packet capture capabilities can be leveraged through the popular Libpcap (Linux) or WinPcap (Windows) library or directly through the Sniffer10G SNF API, which is available as a set of C programming language functions. Using a SNF-aware libpcap/WinPcap, users reference a E-Class network adapter through its Ethernet interface name and then can run existing libpcap/WinPcap-dependent applications, relying on libpcap/WinPcap’s portable interface. For more advanced usage, the SNF API can be directly targeted by user applications. In both usage cases, network access via the SNF interface to the network adapter, rather than via the standard kernel access, provides higher performance.

Regulatory Approvals, Compliance

Emissions Emissions and safety authorities do not certify board-level products. They certify complete systems with all boards installed. To minimize risk for OEM customers, CSPi uses a third-party certification organization to test its Myricom adapters installed into a generic PC. Final test reports are available to customers. We meet US, Canadian, and European emissions, Class A.
Compliance RoHS (Reduction of Hazardous Substances)
Country of Origin USA
