About Myri-10G QP ports:
Although the Myri-10G "QP" Physical layer (PHY) can be used for 10-Gigabit Ethernet applications, QP ports are generally used for HPC applications with MX software and Myrinet network protocols. A QP port uses an industry-standard QSFP (Quad Small Form-factor Pluggable) socket with XAUI signaling per IEEE 802.3ae, electrical power, and the standard QSFP management interface. The advantages of QP ports are low cost, low latency, low power, and the flexibility of being able to use either low-cost, passive, copper cables (10G-QC-xM) up to 5m or Electrical-Optical-Electrical (EOE) fiber cables (10G-QP-xM) up to 200m. (See this Guide to Myri-10G PHYs (pdf)
Performance: This Network Adapter appears to the host operating system as two independent PCI Express devices, one for each network port. Each of the two devices (Lanai-Z8ES chips) can carry traffic at rates approaching 10Gb/s (1.25 GBytes/s). In hosts with sufficient memory and I/O bandwidth, the two devices can together carry traffic between the host and the network at rates approaching 20Gb/s (2.5 GBytes/s) unidirectional and 40Gb/s (5 GBytes/s) bidirectional. If both devices are using the optional MX-10G message-passing system, traffic can be combined using MX Network Adapter bonding, resulting in a unidirectional (MPI PingPong) data rate of ~2.4 GByte/s and a bidirectional (MPI SendRecv) data rate of ~4.7 GByte/s.
Myri-10G network ports (2): QSFP (Quad Small Form factor Pluggable) sockets for QSFP-terminated passive copper cables, QSFP-terminated EOE cables, or QSFP transceivers, 10+10 Gbit/s data rate, full-duplex. The QSFP socket provides XAUI signaling per IEEE 802.3ae, electrical power, and the standard QSFP management interface. The ports 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. When operating in Myrinet mode, the fiber link is limited to 200m by Myrinet flow control. (See this Guide to Myri-10G PHYs (pdf).)
Laser Safety: When used with QSFP transceivers, this is a Class 1M Laser Product. Do not view optical-fiber ports directly with optical instruments.
PCI Express host port: This Network Adapter is an x8 (8 lane) "Gen2" (5 GT/s) PCI Express Add-in Card. It is capable of exchanging data with a host computer at up to 4 GBytes/s (500 MBytes/s per lane) data rate in each direction, full-duplex. This Network Adapter is fully compliant with the PCI Express Card Electromechanical Specification Rev. 2.0, and with the PCI Express Base Specification Rev. 2.0 at 5 GT/s or 2.5 GT/s. The circuit-board edge connector of the Network Adapter will fit mechanically in x8 or x16 physical slots in host computers. The Network Adapter auto-negotiates operation in the widest available mode (x8, x4, x2, or x1) and highest data rate (5 or 2.5 GT/s) supported by the slot it is plugged into.
A PCI Express switch chip connects the host port to two Lanai-Z8ES-based PCI Express endpoints via two x8 (8 lane) PCI Express "Gen1" (2.5 GT/s) links. The Lanai Z8ES is fully compliant with the PCI Express Base Specification Rev. 2.0 (2.5 GT/s only).
Optional PCI Express capabilities supported: Advanced Error Reporting, Function-Level Reset, Device Serial Number, up to 16 outstanding read requests, up to 2KB MaxPayloadSize for all packet types (limited by the PCI Express switch chip), 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 "Gen2" PCI Express network adapters will operate correctly in "Gen1" (2.5 GT/s) PCI Express slots in a host, but require "Gen2" (5 GT/s) PCI Express slots to achieve full performance.
Network Adapter processors and memories(2): The Network Adapter is based on two Myricom Lanai Z8ES chips bridged to the host port with a PCI Express switch chip. Each Lanai Z8ES 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 (2): 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 Network Adapter is operating. The EEPROM can be re-programmed in-place by the Lanai Z8ES.
LEDs (4): The yellow LEDs on the PCI faceplate are controlled by the firmware running in the Lanai for this port. The interpretation of the yellow LEDs is different for different firmware. There is also a green LED for each 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 68.9mm (exclusive of the PCI faceplate), length 170mm (exclusive of the PCI faceplate), total thickness 22mm, weight 84.4g (0.186 pound) including the standard PCI faceplate. The Network Adapter can be supplied with either a standard PCI faceplate (10G-PCIE2-8B2-2QP) or a low-profile PCI faceplate (10G-PCIE2-8B2L-2QP).
Power: Under conditions of maximal bidirectional traffic between the network ports and host, the Network Adapter consumes 10.3W typical, 10.9W maximum, plus any power supplied at the QSFP sockets. Myricom 10G-QC-xM copper cables do not consume power from the QSFP socket. Myricom 10G-QP-xM EOE cables consume 1W typical for each cable end.
Power details: The Network Adapter is powered from both 3.3V and 12V from the PCI Express port. The 3.3V current with maximal bidirectional traffic is 1.2A (3.96W) typical, 1.27A (4.19W) maximum, plus the power used in the QP port by a QSFP transceiver or EOE cable end. In order to remain below the 3A maximum 3.3V current for a PCI Express add-in card, the maximum power available at each QSFP socket is 2.8W. The 12V current is 0.53A (6.36W) typical, 0.56A (6.72W) maximum. Total power is thus 10.32W typical, 10.91W maximum, plus the power used in the QSFP sockets.
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.
