Abstract: Example implementations relate to determining lengths of acknowledgment delays for input/output (I/O) commands. In example implementations, a length of an acknowledgment delay for a respective I/O command may be based on cache availability, and activity level of a drive at which the respective I/O command is directed, after the respective I/O command has been executed. Acknowledgments for respective I/O commands may be transmitted after respective periods of time equal to respective lengths of acknowledgment delays have elapsed.

Abstract: Example implementations relate to determining, based on a system busy level, throughput of logical volumes. In example implementations, a system busy level may be increased in response to a determination that a latency goal associated with one of a plurality of logical volumes has not been met. A throughput for a subset of the plurality of logical volumes may be determined based on the system busy level.

Abstract translation: 示例实现涉及确定用于输入/输出（I / O）命令的确认延迟的长度。 在示例实现中，相应I / O命令的确认延迟的长度可以基于各个I / O命令之后的高速缓存可用性和相应的I / O命令所针对的驱动器的活动级别 执行。 各个I / O命令的确认可以在等于相应的确认延迟的长度已经过去的各个时间段之后被发送。
