Abstract
Techniques are presented for dynamically allocating memory between containers. These techniques include (a) assigning a first portion of memory to a first container and a second portion of memory to a second container, the first and second portions overlapping to form a shared portion of memory assigned to both containers; (b) during a first interval, caching first data in a particular page of the shared portion by first data storage software executing within the first container; (c) during a second interval, caching second data in the particular page of the shared portion by second data storage software executing within the second container; (d) during the first interval, selectively enabling the first data storage software to access the particular page and blocking the second data storage software from accessing the particular page; and (e) during the second interval, selectively enabling the second data storage software to access the particular page and blocking the first data storage software from accessing the particular page.
