Which one do I need?
Match three things. The port and speed must match your switch, with a supported cable or optic: SFP28 for 10 or 25GbE, QSFP28 for 40 to 100Gb/s, QSFP56 for 100 or 200Gb/s, OSFP and QSFP112 for 200 or 400Gb/s. The network must match your fabric: cards listed as InfiniBand and Ethernet (VPI) run either, the rest are Ethernet only. The slot must fit your server: check the PCIe generation and x8 or x16 width. The MCX654106A-HCAT Socket Direct kit uses two x16 slots; Socket Direct ready cards run in one x16 slot and can add a second with the optional extension.
Switches: InfiniBand and Spectrum Ethernet. Cables and optics: DAC, AOC and transceivers.
Every ConnectX card carries our 365-day warranty. Ask us for a quote.
