System and method for performing system memory save in tiered/cached storage

A system for performing a system memory save in non-volatile cached storage, comprising:

• a processor;
• non-volatile cached storage media;
• non-volatile primary storage, wherein the non-volatile cached storage media is operable to cache files for the non-volatile primary storage;
• volatile memory;
• and
• a computer-readable storage medium encoded with processing instructions, wherein the processing instructions when executed:
• determine if available space in a non-volatile primary storage exceeds a reserve requirement;
• invalidate during a sleep state transition a first part of the contents of the non-volatile cached storage media, wherein the invalidation continues until available space of the non-volatile primary storage is large enough to store a second part of the contents of the non-volatile cached storage;
• transfer the second part of the contents of the non-volatile cached storage media to the non-volatile primary storage;
• and
• transfer at least part of the contents of volatile memory to the non-volatile cached storage media.

A non-transitory computer-readable storage medium encoded with processing instructions for implementing a method for performing a system memory save in non-volatile cached storage, the processing instructions for directing an information handling system comprising at least one processor to perform the steps of:

• generating a list of data in a non-volatile cached storage in the information handling system to be invalidated upon transition to a decreased power state;
• receiving a command to transition into the decreased power state;
• finalizing the list of data using a storage driver in the information handling system;
• passing the list of data to a system BIOS;
• determining if available space in a non-volatile primary storage exceeds a reserve requirement;
• invalidating the contents of the non-volatile cached storage identified in the list of data, wherein the invalidating continues until available space of the non-volatile primary storage is large enough to store at least part of the contents of the non-volatile cached storage;
• transferring the at least part of the contents of the non-volatile cached storage to the non-volatile primary storage, wherein the non-volatile cached storage is operable to cache files for the non-volatile primary storage;
• and
• transferring at least part of the contents of volatile memory in the information handling system to the non-volatile cached storage.
