Data access path optimization

A system comprising:

• a memory;
• a plurality of non-uniform memory access (NUMA) nodes, each NUMA node comprising:
• at least one CPU core;
• and
• at least a portion of the memory, attached to the at least one CPU core;
• wherein the memory stores instructions that, when executed by the plurality of NUMA nodes, configures the system to:
• obtain a list of data paths from a first CPU core to at least one persistent storage device;
• associate access performance information with each data path;
• receive a request to access a first persistent storage device of the at least one persistent storage device;
• calculate a preferred data path from the first CPU core to the first persistent storage device using the access performance information;
• and
• access the first persistent storage device using the preferred data path.

A non-transitory computer readable medium comprising instructions which, when executed by one or more processors, cause a computing device to perform steps comprising:

• obtaining a list of data paths from at least one CPU core to at least one persistent storage device;
• associating access performance information with each data path;
• receiving a request to access a first persistent storage device of the at least one persistent storage device;
• calculating a preferred data path from the at least one CPU core to the first persistent storage device using the access performance information;
• and
• accessing the first persistent storage device using the preferred data path.
