MXH930 High Level Specification
The MXH930 is a low profile, half-length PCIe adapter that can be used for NTB and Transparent configurations. Once installed in
any server’s or PC’s PCI Express compliant slot, a
MXH930 can connect to another MXH930, MXH932 or the MXS924 switch. The
MXH930 supports PCIe Gen1, Gen2, Gen3 and Gen4 speeds and x1, x2, x4, x8 and x16 link-widths. The card will operate at the
highest common speed shared between the slot and the card (Gen4) and the widest common link-width (x16).
