Abstract
Systems and/or methods are presented that provide for recording transactions that occur during a write process for the purpose of recovering the transactions in the event of a power loss. In an aspect a system implements an organization that reflects a cache architecture that is organized according to the cache way and set index of each transaction In this regard, the cache way and set index cache architecture provides for a post-power loss search operation that is limited to identifying duplicate locations within the cache-line and keeping only the most recent modification. Thus the system provides pre-organization in terms of self-aggregation by cache way and set index recording that facilitates cache-line eviction processing in the event that the cache is determined to be full.
