Myri-10G network port: SFP+ (Small Form factor Pluggable) socket for an SFP+ transceiver, 10+10 Gbit/s data rate, full-duplex. The SFP+ socket provides SFI 10.3125 GBaud 64b/66b-encoded signaling, electrical power, and the standard SFP+ management interface. The socket does not require the use of SFP+ transceivers purchased from Myricom. The socket may also be used with SFP+-terminated "Direct Attach" twinax copper cables up to 5m, or with SFP+-terminated EOE cables. The port can operate with either Ethernet or Myrinet protocols at the Data Link layer. When operating in Ethernet mode, the port supports Ethernet flow control as defined by IEEE 802.3x. The allowed length of the fiber cable depends upon the SFP+ transceiver and the quality of the fiber, but in Myrinet mode must not exceed 200m due to Myrinet flow control. (See this Guide to Myri-10G PHYs (pdf).)

Laser Safety: When used with 10GBase-SR or 10GBase-LR SFP+ transceivers, this NIC is a Class 1 Laser Product (no biological hazard).

PCI Express host port: This NIC is an x8 (8 lane) PCI Express Add-in Card. It is capable of exchanging data with a host computer at up to 2 GBytes/s (250 MBytes/s per lane) data rate in each direction, full-duplex. This NIC is fully compliant with the PCI Express Card Electromechanical Specification Rev. 2.0, and with the PCI Express Base Specification Rev. 2.0 (2.5 GT/s only). The circuit-board edge connector of the NIC will fit mechanically in x8 or x16 physical slots in host computers. The NIC auto-negotiates operation in the widest available mode (x8, x4, x2, or x1) supported by the slot it is plugged into.

Optional PCI Express capabilities supported: Advanced Error Reporting, Function-Level Reset, Device Serial Number, up to 16 outstanding read requests, up to 4KB MaxPayloadSize for all packet types, MSI and MSI/X, SMBus access.

Optional PCI Express capabilities to be supported in upcoming firmware releases: Address Translation Services, Single Root I/O Virtualization and Sharing, Alternative Routing-ID Interpretation.

These NICs have been tested and qualified in many commercially available motherboards and with all of the common PCI Express chip sets. See this tabulation for the test results with different "Gen1" (2.5 GT/s) PCI Express chip sets. These NICs have also been tested in "Gen2" PCI Express slots, in which the NIC auto-negotiates operation at "Gen1" PCI Express data rates.

NIC processor and memory: The NIC is based on a Myricom custom-VLSI chip, the Lanai Z8ES, which includes a programmable RISC, a set of packet engines, and 2MB of fast SRAM. The RISC, packet engines, and SRAM inside the Lanai-Z8ES chip operate at a clock rate of 364.6MHz. Byte parity is generated and checked on all on-chip memories.

EEPROM: 1MB, which includes the firmware required for PCI device initialization and an Etherboot (UEFI- and PXE-compatible) driver. The driver loads the matching firmware as required by the mode in which the NIC is operating. The EEPROM can be re-programmed in-place by the Lanai Z8ES.

LEDs (2): The yellow LED on the PCI faceplate is controlled by the Lanai firmware; its interpretation is different for different firmware. There is also a green LED for the port: off indicates that the link is down, on indicates that the link is up, and blinking indicates traffic.

Physical characteristics: The circuit board is a low-profile add-in card as defined in the PCI Express Card Electromechanical Specification Rev. 2.0: height 69mm (exclusive of the PCI faceplate), length 112mm (exclusive of the PCI faceplate and connectors), total thickness 22mm, weight 60g (0.132 pound) including the standard PCI faceplate. The NIC can be supplied with either a standard PCI faceplate (10G-PCIE-8B-S) or a low-profile PCI faceplate (10G-PCIE-8BL-S).

Power: The NIC is powered from 3.3V from the PCI Express port. Under conditions of maximal bidirectional traffic between the network port and the host, and with the network port attached to a Direct Attach twinax cable, the NIC consumes 3.9 Watts typical, 4.1 Watts maximum. The use of an SFP+ optical-fiber transceiver adds less than 1 Watt typical.

Environmental: Operating: Temperature 0C to 55C up to 10,000 foot altitude with 100LFM minimum airflow. Relative humidity 15% to 80% @ 50C, non-condensing. Storage: Temperature -40C to 70C. Relative humidity 90% @ 65C.

Regulatory Approvals: Fully compliant with EN55024 (1998 w/A1: 2001 & A2: 2003), EN55022 (1998) Class A, AS/NZS 3548 (1005 W/A1 & A2: 97) Class A, CISPR 22 (1997) Class A, FCC Part 15 Subpart B Section 15.109 Class A, VCCI (April 2000) Class A, & ICES-003 Class A (ANSI C63.4 1992). See the Index of Myri-10G Regulatory Reports.

Reduction of Hazardous Substances: These NICs are RoHS-compliant lead-free (RoHS-6).

Myricom-supported software: These NICs may use the included (bundled) Myri10GE software for 10-Gigabit Ethernet operation, or optional software distributions including MX-10G, Video Pump, Sniffer10G, or DBL. This software is distributed from the Myricom Software & Customer Support page.
