Abstract
A method of operation of a data storage system includes: providing a standby power source; detecting activity on a communication channel with an upstream re-driver powered with the standby power source; generating a signal-detect output from the upstream re-driver based on the activity; determining a link status with a power control unit based on the signal-detect output, the power control unit powered with the standby power source; and generating a power output from a power supply unit based on the link status, the power supply unit controlled by the power control unit.
Claims10
A data storage system comprising:
- a standby power source;
- an upstream re-driver, powered with the standby power source, for detecting activity on a communication channel and generating a signal-detect output;
- a power control unit, coupled to the upstream re-driver, for determining a link status based on the signal-detect output, the power control unit powered with the standby power source;
- and
- a power supply unit, coupled to the power control unit, for generating a power output based on the link status, the power supply unit controlled by the power control unit.
