Abstract

A method for use in a computing device, the method comprising: detecting a request to transmit data, the data including a plurality of data portions, each of the data portions being associated with a respective remote device that the data portion is destined for; identifying a list of addresses that is associated with the request, each of the addresses in the list corresponding to the respective remote device of a different one of the plurality of data portions; detecting whether the request is local; when the request is not local, transmitting the data over a communications network; when the request is local transmitting each of the data portions in the plurality over the respective DMA link that couples the computing device with the data portion's respective remote device.

Dependent claims

A method for use in a computing device, the method comprising:

detecting, by the computing device, a request to transmit data, the data including a plurality of data portions, each of the data portions being associated with a respective remote device that the data portion is destined for;
identifying, by the computing device, a list of addresses that is associated with the request, each of the addresses in the list corresponding to the respective remote device of a different one of the plurality of data portions;
detecting, by the computing device, whether the request is local, the detecting being performed by accessing one or more data structures to determine whether each of the recipient addresses in the list identifies a remote device that is coupled to the computing device via a respective direct memory access (DMA) link;
when the request is not local, transmitting the data over a communications network;
when the request is local detecting whether a predetermined condition is satisfied by the data;
when the predetermined condition is satisfied, transmitting each of the data portions in the plurality over the respective DMA link that couples the computing device with the data portion's respective remote device;
and
when the predetermined condition is not satisfied, transmitting each of the plurality of data portions over the communications network.

5 more elements

A method for use in a computing device, the method comprising:

detecting a request to transmit a data item from the computing device to a remote device;
identifying an address of the remote device;
detecting, by the computing device, whether the remote device is connected to the computing device via a non-transparent bridging (NTB) link;
when the remote device is not connected to the computing device via an NTB link, transmitting the data item from the computing device to the remote device via a communications network;
when the remote device is connected to the computing device via an NTB link, detecting whether the data item satisfies a predetermined condition;
when the predetermined condition is satisfied, transmitting the data item from the computing device to the remote device via the NTB link;
and
when the predetermined condition is not satisfied, transmitting the data item from the computing device to the remote device via the communications network.

5 more elements

A system, comprising:

a memory;
and
at least one processor that is operatively coupled to the memory, the at least one processor being configured to perform the operations of:
detecting an I/O request to transmit a data item to a remote device;
identifying an address of the remote device;
detecting, based on the address, whether the remote device is connected to the system via a non-transparent bridging (NTB) link;
when the remote device is not connected to the system via an NTB link, transmitting the data item to the remote device via a communications network;
when the remote device is connected to the system via an NTB link, detecting whether the data item satisfies a predetermined condition;
when the predetermined condition is satisfied, transmitting the data item to the remote device via the NTB link;
and
when the predetermined condition is not satisfied, transmitting the data item to the remote device via the communications network.
