Abstract
A technique operates data storage equipment. The technique involves, during a first time period and while processing circuitry performs host I/O operations on behalf of a set of hosts, performing a data identification operation which provides a data identification result identifying particular data which is routinely accessed by the processing circuitry. The technique further involves, during a second time period after the first time period and in response to the data identification result, copying the particular data from secondary storage to an extension cache which forms part of primary storage to pre-fetch the particular data from the secondary storage for subsequent use by the processing circuitry. The technique further involves, during a third time period after the second time period and while the processing circuitry performs further host I/O operations on behalf of the set of hosts, accessing the particular data from the extension cache.
