Storage address space to nvm address, span, and length mapping/converting

A method comprising:

• determining, based at least in part on a host storage space address, an element describing a transfer amount value in units of a transfer amount granularity, and a space amount value in units of a space amount granularity;
• determining, based at least in part on the element, the transfer amount value, and the space amount value;
• reading, from a Non-Volatile Memory (NVM), data corresponding to the host storage space address, based at least in part on the transfer amount value;
• tracking space usage information of the NVM based at least in part on the space amount value;
• and
• wherein the transfer amount granularity is greater than the space amount granularity.

A non-transitory tangible computer readable medium having a set of instructions stored therein that when executed by a processing element cause the processing element to perform operations comprising:

• determining, based at least in part on a host storage space address, an element describing a transfer amount value in units of a transfer amount granularity, and a space amount value in units of a space amount granularity;
• determining, based at least in part on the element, the transfer amount value, and the space amount value;
• reading, from a Non-Volatile Memory (NVM), data corresponding to the host storage space address, based at least in part on the transfer amount value;
• tracking space usage information of the NVM based at least in part on the space amount value;
• and
• wherein the transfer amount granularity is greater than the space amount granularity.
