81.2.IntroductionThis is the User Guide for Ethernet adapter cards based on the ConnectX®-5 and ConnectX®-5 Exintegrated circuit device for OCP Spec 3.0. These adapters connectivity provide the highestperforming low latency and most flexible interconnect solution for PCI Express Gen 3.0/4.0 serversused in Enterprise Data Centers and High-Performance Computing environments.Important Notes:ConnectX-5 OCP 3.0 cards were tested for Shock & Vibe in accordance with NVIDIAspecifications and setup, as the OCP spec 3.0 available at that time did not contain any S&Vdefinitions. A newer version of the OCP spec 3.0 has defined S&V specifications and NVIDIA isin the midst of retesting these cards to comply with OCP spec 3.0.In some of the OCP 3.0 cards, the insertion force that is required to install the card into aparticular PCI connector may exceed the maximum insertion force that is allowed by theconnector’s spec. NVIDIA is updating the OCP 3.0 cards to ensure the proper insertionprocess.The following tables provide the ordering part number, port speed, number of ports, and PCI Expressspeed per ConnectX-5 and ConnectX-5 Ex OPNs.ConnectX-5 Ex Adapter Cards for OCP 3.0Part Number MCX566M-GDAIMCX565M-CDAIMCX565M-CDABMCX566A-CDAIMCX566A-CDABEthernet Data Rate Up to 50Gb/s Up to 100Gb/s Up to 100Gb/s Up to 100Gb/s Up to 100Gb/sNetwork ConnectorTypex2 QSFP28 ports x1 QSFP28 port x1 QSFP28 port x2 QSFP28 ports x2 QSFP28 portsPCI ExpressConnectorsPCIe Gen 3.0 / 4.0 x16 (a), (b)SERDES @ 8.0GT/s / 16.0GT/sBracket Internal-LockBracketInternal-LockBracketPull-tab Bracket Internal-LockBracketPull-tab bracketHost Management ✔ ✔ ✔ ✔ ✔Multi-Host/ SocketDirect✔ ✔ ✔ NA NAIC Part Number MT28804A0-FCCF-CEMMT28804A0-FCCF-CEMMT28804A0-FCCF-CEMMT28808A0-FCCF-CEMT28808A0-FCCF-CEDevice ID 4121 for Physical Function (PF)4122 for Virtual Function (VF)Form FactorDimensionsSmall Form Factor (SFF)4.52in. x 2.99in.
