Key Features· Low-profile PCI Express x8 add-in card· Dual protocol, 10-Gigabit Ethernet or 10-Gigabit Myrinet· Wire-speed performance· Firmware-controlled offloads· MTBF: 5M hours (FIT rate = 200)Myri-10G network port10GBase-R, 10+10 Gbit/s data rate, full-duplex. Serial data is carried on a single fiber in each direction at 10.3125 GBaud, 64b/66b-encoded. Depending upon the XFP transceiver plugged into the socket in the PCI faceplate, the port is 10GBase-SR (850nm wavelength, 26-300m on multimode fiber), 10GBase-LR (1310nm wavelength, up to 10km on single-mode fiber), or 10GBase-ER (1550nm wavelength, up to 40km on single-mode fiber). 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 XFP transceiver and the quality of the fiber, but in Myrinet mode must not exceed 200m due to Myrinet flow control.PCI Express host portThis Network Adapter is a 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. The port is fully compliant with the PCI Express Card Electromechanical Specification Rev. 1.1, and with the PCI Express Base Specification Rev. 1.1. 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) supported by the slot it is plugged into.Optional PCI Express capabilities supported: Advanced Error Reporting, Device Serial Number. Firmware with Completion Timeout Control capability is available upon request.These network adapters have been tested and qualified in many commercially available motherboards and with all of the common PCI Express chip sets.Network Adapter processorThe Network Adapter is based on a Myricom custom-VLSI chip called the Lanai Z8E. The RISC and other processors inside the Lanai-Z8E chip operate at 300MHz minimum.Local memory: 2MB (256Kx8B). The local memory operates from the same 300MHz clock as the processors in the Lanai Z8E, and provides 2,400 MB/s of local-memory bandwidth. Byte parity is generated and checked on all on-chip and off-chip memories. The local memory is used principally for firmware execution and for buffering packet headers. Packet data is buffered inside the Lanai Z8E.EEPROM512KB, which includes the firmware required for PCI device initialization and an Etherboot (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 Z8E.LEDs (4)The yellow LED labeled S on the PCI faceplate is controlled by the Lanai firmware; its interpretation is different for different firmware. The 3 green LEDs on the PCI faceplate indicate Link connectivity, RX traffic, and TX traffic, and are labeled L, R, and T, respectively.Physical dimensionsThe circuit board is a low-profile add-in card as defined in the PCI Express Card Electromechanical Specification Rev. 1.1: height 68.9mm (exclusive of the PCI faceplate), length 165.1mm (exclusive of the PCI faceplate), total thickness 22mm, weight 91g (including the standard PCI faceplate, and without a XFP transceiver). The Network Adapter can be supplied with either a standard PCI faceplate (10G-PCIE-8A-R) or a low-profile PCI faceplate (10G-PCIE-8AL-R).PowerThe Network Adapter (with an XFP transceiver installed) is powered from 3.3V and 12V from the PCI Express port, 2.5A and 0.14A maximum, respectively, a total of 10W maximum.Environmental· Operating: Temperature 0C to 55C up to 10,000 foot altitude. Relative humidity 15% to 80% @ 50C, non-condensing. Storage: Temperature -40C to 70C. Relative humidity 90% @ 65C.· Test connector: The test connector is used for Myricom's production testing, and should not be used in normal service.Regulatory ApprovalsFully compliant with TAA, 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).
