System and method of providing atomicity to large writes to persistent memory

Abstract

A system and a method are disclosed that provides atomicity for large data writes to persistent memory of an object storage system. A segment of persistent memory is allocated to an application. The persistent memory includes non-volatile memory that is accessible in a random access, byte-addressable manner. The segment of persistent memory is associated with first and second bits of a bitmap. The first bit is set indicating that the segment of persistent memory has been allocated. Data is received from the application for storage in the segment of persistent memory, and the second bit is set indicating that data in the segment of persistent memory has been finalized and is ready for storage in a storage medium that is different from persistent memory. The atomicity of the data in persistent memory may be determined based on the first bit and the second bit being set.

Dependencies are inferred from the claim text.
