An illustrative embodiment of a computer-implemented process for logical buffer pool extension identifies a page in a memory for eviction, analyzes characteristics of the page to form a differentiated page, wherein the characteristics of the page comprise descriptors including a workload type, a page weight, a page type, frequency of access and timing of most recent access and identifies a target location for the differentiated page from a set of locations including a fastcache storage and a hard disk storage to form an identified target location. The process further selects an eviction operation from a set of eviction operations using the characteristics of the differentiated page and the identified target location and writes the differentiated page to the identified target location using the selected eviction operation wherein the differentiated page is written only to the fastcache storage. |
