Dynamic creation and destruction of io resources based on actual load and resource availability

A system, comprising:

• a plurality of Non-Uniform Memory Access (NUMA) nodes comprising:
• a NUMA node comprising a processor and a memory;
• a NUMA I/O Framework executing on at least one of the plurality of NUMA nodes, configured to:
• bind an I/O object group to the NUMA node;
• obtain an I/O object group size of the I/O object group;
• determine an I/O object group target size based on an I/O object group aggregate load of the I/O object group;
• compare the I/O object group target size and the I/O object group size;
• send the I/O object group target size to an I/O Subsystem associated with the I/O object group in response to a determination that a difference between the I/O object group target size and the I/O object group size exceeds a threshold;
• and
• instruct the I/O Subsystem to change the I/O object group size using the I/O object group target size;
• and
• the I/O Subsystem executing on at least one of the plurality of NUMA nodes, configured to:
• receive the I/O object group target size;
• receive the instruction to change the I/O object group size;
• and
• change the I/O object group size using the I/O object group target size, wherein after the changing, the I/O object group size is equal to the I/O object group target size.

A method for binding input/output (I/O) objects to nodes, the method comprising:

• binding, by a Non-Uniform Memory Access (NUMA) input/output (I/O) Framework, an I/O object group to a NUMA node of a plurality of NUMA nodes on a system, wherein the I/O object group comprises a first I/O object corresponding to a first thread and a second I/O object corresponding to an interrupt;
• obtaining an I/O object group size of the I/O object group;
• determining an I/O object group target size based on a first I/O object effective load of the first I/O object and a second I/O object effective load of the second I/O object;
• comparing, by the NUMA I/O Framework, the I/O object group target size and the I/O object group size;
• determining, by the NUMA I/O Framework, that a difference between the I/O object group target size and the I/O object group size exceeds a threshold;
• and
• instructing, by the NUMA I/O Framework, a Network Media Access Connection (MAC) Layer associated with the I/O object group to change the I/O object group size, wherein the Network MAC Layer changes, in response to the instruction, the I/O object group size.
