Abstract
Cache prefetching in offloaded data transfer (ODX) processes. A populate token command is received to initiate a copy offload operation. Responsive to receiving the populate token command, a cache of a data storage system in a storage area network environment is instructed to prefetch data in accordance with the populate token command and complete an offloaded read request. Responsive to determining that a write using token command is not received within a specified time duration, the prefetched data stored in the cache is evicted.
