Data storage system adapted to select an operational state with corresponding performance levels and acoustic noise levels based on a system profile

摘要

The present invention may be regarded as a data storage system and a method of controlling the acoustic noise generated by a storage drive of a data storage system. The data storage system includes a storage drive adapted to operate in a selected operational state of a plurality of operational states. Each operational state generates a corresponding acoustic noise level and operates at a corresponding performance level. The data storage system further includes a system controller coupled to the storage drive, the system controller including a system profile. The system controller is adapted to: (a) receive at least one variable parameter; (b) use the at least one variable parameter as an index to the system profile to autonomously select one of the plurality of operational states as the selected operational state; and (c) transmit a control signal to the storage drive. The control signal corresponds to the selected operational state and causes the storage drive to enter the selected operational state, thereby controlling the acoustic noise and the performance level of the storage drive in response to the at least one variable parameter.
