A storage enclosure connected to a server via an external network and includes a network switch, an expander that is connected to the network switch and that is configured to generate enclosure data that supports a format conforming with SCSI Enclosure Services, and a board management controller (BMC) that is connected to the network switch and the expander. The BMC is configured to translate the enclosure data into enclosure translating data that supports a Redfish® format. The expander is configured to, after generating the enclosure data, transmit the enclosure data through the network switch to the BMC via an internal network. The BMC is configured to translate the enclosure data into the enclosure translating data, and to transmit the enclosure translating data to the network switch. The network switch transmits the enclosure translating data to the server through the external network.

Storage enclosure and system including the storage enclosure

A method of power management includes steps of: in response to receiving from a server host a sleep command, an expander first outputting a predetermined register value to a processing unit in a normal state, and then switching to a power-saving state and outputting an interrupt signal to the processing unit; the processing unit determining whether both the predetermined register value and the interrupt signal are received; and when it is determined that both the predetermined register value and the interrupt signal have been received, the processing unit controlling a power supply to output standby electricity, making the expander and the processing unit operate based on the standby electricity.

Method of power management using an expander for a storage system

A control system for a storage apparatus includes two input/output modules (IOMs), and two non-volatile memory (NVM) devices that are electrically connected to the IOMs, respectively, and that each store a firmware code. Each of the IOMs is configured to execute a firmware corresponding to the firmware code stored in the corresponding NVM device, and to enter an active mode or a passive mode after executing the firmware. The IOMs are configured such that when one IOM operating in the passive mode detects abnormal operation of the other IOM operating in the active mode, the one IOM sends, to the other IOM, the firmware code stored in the NVM device electrically connected to the one IOM, in order to update the firmware code in the NVM device electrically connected to the other IOM.
