Appl. No.:

14/977699

International Classification:

G06F 3/06
G06F 12/06

Abstract:

A system and method for allocating different temperature data to storage devices within a computer system including inexpensive non-volatile storage, such as hard disk drive (HDD) storage devices; expensive non-volatile storage, such as solid-state drive (SSD) storage devices; and expensive volatile storage, such as system cache memory. The system and method allocates cold to warm data having access frequencies up to a first access frequency threshold to inexpensive non-volatile storage; allocates hot data having access frequencies greater than the first access frequency value and ranging up to a second access frequency threshold, to expensive non-volatile storage; and allocates very hot data having access frequencies greater than the second access frequency value and which resides during normal system operation in expensive volatile storage, to said inexpensive non-volatile storage.
