ABSTRACT:
Performing a cache only data transfer across a bus connecting a storage apparatus with a host concurrent with a period of bus availability while being incident within a time period for executing a connect host data transfer command. The time period for executing the connect host data transfer command is determined by a combination of a seek latency portion of the connect host data transfer command execution in combination with a rotation latency portion of the connect host data transfer command execution offset by a data transfer latency between the storage apparatus and the host in combination with an overhead time, wherein the overhead time is determined by a time for determining the time period for executing the connect host data transfer command in conjunction with a time for stopping an operation of the storage apparatus and transitioning to a new operation of the storage apparatus.
