D2 Application Note 2
Configuring dimmPCI Modules for Communication
April 21, 2003
Version 0.1
Authors: Bernice Lau, Robert Austen
Abstract
On a dimmPCI backplane, there are several possible slots in which a dimmPCI may be inserted, the system slot or the peripheral slots. With the correct options compiled into the kernel and system configuration, the two modules can be set up to communicate with each other. The communication is achieved using the PCI I2O transport layer to send ethernet packets over the PCI bus to another likewise configured module.
Introduction
In order to connect the two dimmPCI modules, it is necessary to set up the hardware as a subnet. A NETdimm must be in the system slot to interface to the local network through the ethernet port.
