1. A system, comprising:
a chassis;
a processor in the chassis;
a switch in the chassis;
a storage device in the chassis, the storage device including a storage and a controller configured to store data in the storage based at least in part on a write request received from a remote processor outside the chassis and to retrieve data from the storage based at least in part on a read request from the remote processor, the storage device communicating with the remote processor through the switch, the storage device supporting an active power mode and a low power mode, wherein the remote processor sends a message to the storage device and the storage device is in the low power mode; and
a component configured to receive from the switch a message sent from the remote processor to the storage device and to generate and send a response to the message to the remote processor, the response based at least in part on a content of the message,
wherein the component includes the processor or a management controller, and
wherein the switch is configured to direct commands addressed to the storage device in the low power mode to the component.
