Mellanox Part Numbering Legend
Table 4 describes the Mellanox Technologies adapter cards part numbering legend.
For example, the part number MHGH28-XSC describes Mellanox Technologies’ ConnectX™ IB HCA card with
dual CX4 ports, a PCIe2.0 x8 2.5GT/s interface, no on-board memory (mem-free), a short PCI bracket, and RoHS R5
compliance. Using the legend,
• field M = M to indicate a Mellanox Technologies product,
• field H = H to indicate an InfiniBand Adapter Card,
• field T = G to indicate CX4 DDR,
• field S = H to indicate the ConnectX family,
• field # = 2 to indicate two ports,
• field I = 8 to indicate PCI Express 2.0 x8 running at 2.5GT/s,
• field X = X to indicate no on-board memory,
• field B = S to indicate a short bracket, and
• field R = C to indicate RoHS R5 (w/ Exemptions) compliance
