Abstract: Examples described herein include a computer system, implemented on a node cluster including at least a first node and a second node. The computer system monitors data access requests received by the first node. Specifically, the computer system monitors data access requests that correspond with operations to be performed on a data volume stored on the second node. The system determines that a number of the data access requests received by the first node satisfies a first threshold amount and, upon making the determination, selectively provisions a cache to store a copy of the data volume on the first node based, at least in part, on a system load of the first node.
