Intelligent Redundant Array of Independent Disks

A system for managing a RAID file system memory, the system comprising:

• a) a coalescing module configured to coalesce small read and write chunks into reasonably sized coalesced chunks up to 1 MB without any small size I/Os (input/outputs);
• b) a new mapping layer module configured to map the small size chunks in the coalesced chunks;
• and
• c) a flushing module configured to flush the chunks by allocating large chunks based on a chunk size coalescence or on a check point hit in terms of a SPA Sync.

A non-transitory processor-readable storage medium having one or more instructions which when executed by at least one processing circuit causes the at least one processing circuit to:

• a) coalesce a plurality of small read and write chunks into reasonably sized chunks up to 1 MB chunks without any small size I/Os (input/outputs);
• b) create a new mapping layer configured to map the small size chunks in the coalesced chunks;
• and
• c) flush the chunks by allocating large chunks based on a chunk size coalescence or a check point is hit in terms of a SPA Sync.
