Abstract
A storage system includes a first storage device and a second storage device, a first programmable chip of the first storage device and a second programmable chip of the second storage device are connected in series, and the second storage device is in a sleep state. The first programmable chip sends a wakeup instruction to the second programmable chip to instruct the second storage device to enter a working state. In this way, the second storage device is switched from the sleep state to the working state by using a programmable chip of the storage device.
Claims7
A storage system, comprising at least two storage devices, wherein the at least two storage devices are connected together in series, each of the at least two storage devices comprising a programmable chip, the programmable chip being configured to perform baseboard management for the storage device, and the at least two storage devices comprise a first storage device and a second storage device, wherein a first programmable chip of the first storage device and a second programmable chip of the second storage device are connected together in series, and wherein
- when the second storage device is in a sleep state, the sleep state indicating that only the second programmable chip is in a power-on state:
- the first programmable chip is configured to send a wakeup instruction to the second chip;
- and
- the second programmable chip is configured to:
- receive the wakeup instruction sent by the first programmable chip, and control, based on the wakeup instruction, the second storage device to enter a working state, wherein the working state indicates that all elements of the second storage device are in the power-on state.
A method for transmitting a signal in a storage system, wherein the storage system comprises at least two storage devices, the at least two storage devices are connected in series, each of the at least two storage devices comprising a programmable chip, the programmable chip being configured to perform baseboard management for the storage device, and the at least two storage devices comprise a first storage device and a second storage device, wherein a first programmable chip of the first storage device and a second programmable chip of the second storage device are connected in series, and, wherein the method comprises
- when the second storage device is in a sleep state, the sleep state indicating that only the second programmable chip is in a power-on state:
- sending, by the first programmable chip, a wakeup instruction to the second programmable chip;
- and
- receiving, by the second programmable chip, the wakeup instruction sent by the first programmable chip, and controlling, based on the wakeup instruction, the second storage device to enter a working state, wherein the working state means that all elements of the second storage device are in a power-on state.
