Performance improvement for an active-active distributed non-ALUA system with address ownerships

A system, comprising:

• a memory comprising computer-executable instructions;
• and
• a processor executing the computer-executable instructions, the computer-executable instructions when executed by the processor cause the processor to perform operations comprising:
• receiving, by a routing module of a content-addressable storage system, an input/output (IO) request;
• determining, by the routing module from a table that provides a listing of addresses and compute nodes having ownership to the address, a target location of the IO request, the target location specifying an address;
• determining, by the routing module, a mapping between each of the compute modules and a physical path to corresponding storage controllers, and an address owner of a storage controller port of a storage controller that owns the address of the IO;
• selecting a physical path associated with the address owner;
• and
• transmitting, by the routing module, the IO request to the storage controller port via a direct call.

A computer program product embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a computer causes the computer to perform operations comprising:

• receiving, by a routing module of a content-addressable storage system, an input/output (IO) request;
• determining, by the routing module from a table that provides a listing of addresses and compute nodes having ownership to the address, a target location of the IO request, the target location specifying an address;
• determining, by the routing module, a mapping between each of the compute modules and a physical path to corresponding storage controllers, and an address owner of a storage controller port of a storage controller that owns the address of the IO;
• selecting a physical path associated with the address owner;
• and
• transmitting, by the routing module, the IO request to the storage controller port via a direct call.
