Abstract

A NUMA-aware storage system including a first processing subsystem coupled to a first memory subsystem, and a second processing subsystem coupled to a second memory subsystem. A first NTB subsystem connected to the first processing subsystem presents itself as a first storage device, identifies first data transfer operations directed to the first memory subsystem and, in response, claims those first data transfer operations and provides them directly to the first processing subsystem. A second NTB subsystem connected to the second processing subsystem presents itself as a second storage device, identifies second data transfer operations directed to the second memory subsystem and, in response, claims those second data transfer operations and provides them directly to the second processing subsystem. A storage controller system receives a command from either the first or second processing subsystem via the first or second NTB subsystem and, in response, transmits that command to a storage system.

Dependent claims

A Non-Uniform Memory Access (NUMA)-aware storage system, comprising:

a first processing subsystem coupled to a first memory subsystem;
a second processing subsystem coupled to a second memory subsystem;
a storage system;
and
a storage controller system that is coupled to the storage system and that includes:
a first Non-Transparent Bridge (NTB) subsystem that is connected to the first processing subsystem and that is configured to:
present the first NTB subsystem to the first processing subsystem as a first storage device;
and
identify first data transfer operations directed to the first memory subsystem and, in response, claim those first data transfer operations and provide them directly to the first processing subsystem;
a second NTB subsystem that is connected to the second processing subsystem and that is configured to:
present the second NTB subsystem to the second processing subsystem as a second storage device;
and
identify second data transfer operations directed to the second memory subsystem and, in response, claim those second data transfer operations and provide them directly to the second processing subsystem;
and
wherein the storage controller system is configured to:
receive a command from either the first processing subsystem via the first NTB subsystem or the second processing subsystem via the second NTB subsystem and, in response, transmit that command to the storage system.

An Information Handling System (IHS), comprising:

a first Non-Transparent Bridge (NTB) subsystem that is connected to a first processing subsystem and that is configured to:
present the first NTB subsystem to the first processing subsystem as a first storage device;
and
identify first data transfer operations directed to a first memory subsystem that is connected to the first processing subsystem and, in response, claim those first data transfer operations and provide them directly to the first processing subsystem;
a second NTB subsystem that is connected to a second processing subsystem and that is configured to:
present the second NTB subsystem to the second processing subsystem as a second storage device;
and
identify second data transfer operations directed to a second memory subsystem that is connected to the second processing subsystem and, in response, claim those second data transfer operations and provide them directly to the second processing subsystem;
a controller processing system that is coupled to the first NTB subsystem and the second NTB subsystem;
and
a controller memory system that is coupled to the controller processing system and that includes instructions that, when executed by the controller processing system, cause the controller processing system to provide a storage controller engine that is configured to:
receive a command from either the first processing subsystem via the first NTB subsystem or the second processing subsystem via the second NTB subsystem and, in response, transmit that command to a storage system.

A method for storing data in a Non-Uniform Memory Access (NUMA)-enabled computing device, comprising:

presenting, by a first Non-Transparent Bridge (NTB) subsystem, the first NTB subsystem to a first processing subsystem as a first storage device;
and
identifying, by the first NTB subsystem, first data transfer operations directed to a first memory subsystem that is connected to the first processing subsystem and, in response, claiming those first data transfer operations and providing them directly to the first processing subsystem;
presenting, by a second NTB subsystem, the second NTB subsystem to a second processing subsystem as a second storage device;
and
identifying, by the second NTB subsystem, second data transfer operations directed to a second memory subsystem that is connected to the second processing subsystem and, in response, claiming those second data transfer operations and providing them directly to the second processing subsystem;
receiving, by a storage controller engine, a command from either the first processing subsystem via the first NTB subsystem or the second processing subsystem via the second NTB subsystem and, in response, transmitting that command to a storage system.
