1.2 Mellanox Part Numbering Legend

Table 4 describes the Mellanox Technologies adapter cards part numbering legend.

For example, the part number MHQH29-XSC describes Mellanox Technologies’ ConnectX

HCA card with dual QSFP ports, a PCIe2.0 x8 5.0GT/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 = Q to indicate QSFP QDR,

• field S = H to indicate the ConnectX family,

• field # = 2 to indicate two ports,

• field I = 9 to indicate PCI Express 2.0 x8 running at 5.0GT/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
