Optimizing storage system performance using storage device topology

A storage system comprising:

• a plurality of solid-state storage devices;
• and
• a storage system controller, operatively coupled to the plurality of solid-state storage devices, the storage system controller comprising a processing device, the processing device to:
• receive, from a storage controller, a topology of a solid-state storage device of the plurality of solid-state storage devices;
• identify a plurality of schedulable units of the solid-state storage device that are configured to perform parallel access operations based on the topology;
• determine which of the plurality of schedulable units are associated with other access operations that have been scheduled to be performed by the solid-state storage device;
• schedule a write operation to be performed by one or more of the plurality of schedulable units that are not associated with the other access operations that have been scheduled to be performed by the solid-state storage device;
• and
• perform the write operation to store data at the solid-state storage device based on the scheduling.

A method comprising:

• receiving, from a storage controller, a topology of a solid-state storage device of a storage system;
• identifying a plurality of schedulable units of the solid-state storage device that are configured to perform parallel access operations based on the topology;
• determining which of the plurality of schedulable units are associated with other access operations that have been scheduled to be performed by the solid-state storage device;
• scheduling, by a processing device, a write operation to be performed by one or more of the plurality of schedulable units that are not associated with the other access operations that have been scheduled to be performed by the solid-state storage device;
• and
• performing the write operation to store data at the solid-state storage device based on the scheduling.

A non-transitory computer readable storage medium storing instructions, which when executed, cause a processing device of a storage system controller to:

• receive, from a storage controller, a topology of a solid-state storage device of a storage system;
• identify a plurality of schedulable units of the solid-state storage device that are configured to perform parallel access operations based on the topology;
• determine which of the plurality of schedulable units are associated with other access operations that have been scheduled to be performed by the solid-state storage device;
• schedule, by the processing device, a write operation to be performed by one or more of the plurality of schedulable units that are not associated with the other access operations that have been scheduled to be performed by the solid-state storage device;
• and
• perform the write operation to store data at the solid-state storage device based on the scheduling.
