Storage system, method, and apparatus for fast IO on PCIE devices

A system for data processing comprising:

• a device to:
• receive a request, the request comprising instructions for communicating data between the device and a system, the system comprising a processing device and a memory device, wherein the memory device is separate from the processing device;
• determine, based on the request, a communication path for communicating the data with the system, wherein the communication path is selected from a first communication path for communicating the data from the device to the processing device and a second communication path for communicating the data from the device to the memory device;
• and
• generate a routing instruction based on the communication path;
• and
• a data transfer device coupled to the device, the data transfer device communicating the routing instruction to the system;
• wherein the system is configured to:
• route a first packet of the data from the device to one of the processing device and the memory device according to the routing instruction;
• and
• route a second packet of the data from the device to one of the processing device and the memory device according to the routing instruction.

An apparatus for data processing comprising:

• a system;
• and
• a data transfer device coupled to a device and configured to:
• generate a routing instruction;
• communicate the routing instruction to the system;
• wherein the routing instruction is based on a selection of one of a first communication path for communicating the data from the device to the data transfer device and a second communication path for communicating the data from the device to a memory device, wherein the data transfer device is separate from the memory device, the selection being determined based on one or more instructions included in a request;
• wherein the system is configured to:
• route a first packet of the data from the device to one the data transfer device and the memory device according to the routing instruction;
• and
• route a second packet of the data from the device to one of the data transfer device and the memory device according to the routing instruction.
