Abstract
Machines, systems and methods for I/O monitoring in a plurality of compute nodes and a plurality of service nodes utilizing a Peripheral Component Interconnect express (PCIe) are provided. In one embodiment, the method comprises assigning at least one virtual function to a services node and a plurality of compute nodes by the PCIe interconnect and a multi-root I/O virtualization (MR-IOV) adapter. The MR-IOV adapter enables bridging of a plurality of compute node virtual functions with corresponding services node virtual functions. A front-end driver on the compute node requests the services node virtual function to send data and the data is transferred to the services node virtual function by the MR-IOV adapter. A back-end driver running in the services node receives and passes the data to a software service to modify/monitor the data. The back-end driver sends the data to another virtual function or an external entity.
