Physical media aware spacially coupled journaling and replay

A computer-implemented method, comprising:

• receiving a write request to store data to a solid state drive (SSD);
• storing the data to a physical data location in a cluster block on the SSD;
• updating an indirection mapping table based at least in part on the write request, the indirection mapping table mapping physical data locations on the SSD to logical addresses;
• generating an entry to a journal based at least in part on the write request;
• detecting a journal storage event;
• storing the journal to a predetermined location on the SSD, wherein the predetermined location causes the stored journal to be co-located with the data it describes in the cluster block, and wherein the storing the journal is based at least in part on the number of entries stored by the journal;
• and
• generating a new indirection mapping table using at least the journal stored at the predetermined location.

A system, comprising:

• at least one processor;
• and
• memory including instructions that, when executed by the at least one processor, cause the system to:
• receive a write request to store data to a solid state drive (SSD);
• store the data to a physical data location in a cluster block on the SSD;
• update an indirection mapping table based at least in part on the write request, the indirection mapping table mapping physical data locations on the SSD to logical addresses;
• generate an entry to a journal based at least in part on the write request;
• detect a journal storage event;
• store the journal to a predetermined location on the SSD, wherein the predetermined location causes the stored journal to be co-located with the data it describes in the cluster block, and wherein the storing the journal is based at least in part on the number of entries stored by the journal;
• and
• generate a new indirection mapping table using at least the journal stored at the predetermined location.
