Abstract
Smart weighted container data cache eviction preserves write evict units (WEUs) containing the most frequently and recently accessed blocks to maintain low latency data cache. Prior to performing cache eviction, the WEUs are weighted based on the page statistics maintained for each WEU. Page statistics include page hit/frequency and recency statistics associated with each WEU and data cache eviction is performed at the WEU level of granularity. Therefore, an entire WEU can be evicted based on page hit/frequency and recency statistics associated with the WEU.
