Abstract:
A method of managing asynchronous I/O initiation requests within a coprocessor of a computing environment, said method comprising:obtaining by said coprocessor one or more asynchronous I/O initiation requests for initiating execution of one or more I/O operations, said one or more asynchronous I/O requests being associated with one or more partitions of said computing environment, and said one or more partitions including one or more operating systems; and initiating an asynchronous I/O initiation request of said one or more asynchronous I/O initiation requests, said asynchronous I/O initiation request to be used to initiate execution of at least one I/O operation, and said initiating comprising selecting said asynchronous I/O initiation request using (i) at least one priority assigned to at least one asynchronous I/O initiation request of said one or more asynchronous I/O initiation requests, and (ii) at least one priority assigned to at least one partition of said one or more partitions, wherein said (ii) at least one priority is dynamically adjusted by a workload manager considering workload goals of said at least one partition.
