Abstract:
Stage task control blocks (TCB) are allocated for performing staging operations in a storage controller controlling one or more storage ranks. Destage TCBs are allocated for performing destaging operations in the storage controller. The storage controller adjusts how many stage TCBs and destage TCBs are to be allocated based on response times of the one or more storage ranks.
