8 InfiniBand Fabric
8.1 Network Direct Interface
The Network Direct Interface (NDI) architecture provides application developers with a net-
working interface that enables zero-copy data transfers between applications, kernel-bypass I/O
generation and completion processing, and one-sided data transfer operations.
NDI is supported by Microsoft and is the recommended method to write InfiniBand application.
NDI exposes the advanced capabilities of the Mellanox networking devices and allows applica-
tions to leverage advances of InfiniBand.

8.2 part_man - Virtual IPoIB Port Creation Utility
part_man is used to add/remove virtual IPoIB ports. Currently, each Mellanox IPoIB port can
have a single virtual IPoIB only which is created with a PKey value of 0xffff.
 Usage
• -v: increases verbosity level.
• Show: shows the currently configured virtual ipoib ports.
• Add: adds new virtual IPoIB port. Where add should be used with interface name, as it
appears in Network connection in the control panel.
• Name: any printable name without quotations marks (“ ”), commas, and starting with i.
• Rem: removes existing virtual IPoIB port. Therefore, it requires running it with Show,
then copy the parameters.
 Example
Adding and removing virtual port:
8.3 InfiniBand Fabric Diagnostic Utilities
The diagnostic utilities described in this chapter provide means for debugging the connectivity
and status of InfiniBand (IB) devices in a fabric.
8.3.1 Utilities Usage
This section first describes common configuration, interface, and addressing for all the tools in
the package. Then it provides detailed descriptions of the tools themselves including: operation,
synopsis and options descriptions, error codes, and examples.
