Abstract
A system for minimizing power consumption of a multiprocessor data storage system is disclosed. The system utilizes processors that are capable of operating at a number of different reduced power modes, such that the processors operate at full power during peak workloads, but can be powered down during low workload times. When the onset of peak loads are detected through monitoring I/Os per second (“IOPS”) and/or response times of the system, the processors are brought out of power-down mode to handle the increased IOPS during the peak loads. In this manner, the majority of the processors only operate at full power when the system experiences peak loads. During normal and low load times, the processors are either operated at reduced power or are powered down. This results in a significant reduction in power consumption of the system.
