Key-per-io multiple tenant isolation

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller is configured to:
• maintain a first controller key index list, wherein the first controller key index list includes a plurality of first controller key entries and wherein a first controller key index first entry comprises a first value;
• maintain a second controller key index list, wherein the second controller key index list includes a plurality of controller key entries and
• wherein a second controller key index first entry comprises the first value;
• receive an instruction to update the first controller key index list or the second controller key index list;
• update the first controller key index list;
• and
• perform data transfer using the first controller key index list.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, the controller including:
• a data path;
• and
• a control path, wherein the control path includes:
• a namespace/key indexing module;
• a processor;
• a mux coupled to the processor;
• a first indirect list module coupled between the mux and the namespace/key indexing module;
• and
• a second indirect list module coupled between the mux and the namespace/key indexing module.
