Abstract: A firmware inventory system for efficient firmware inventory of storage devices in an information handling system may include a first storage subsystem. The first storage subsystem may include a first set of storage devices, a first inventory information table, and a first expander. The expander may include a first memory, a first processor, and a first virtual SEP device stored in the first memory and executable by the first processor. The first virtual SEP device may, when a device change event is received from a first storage device of the first set of storage devices, send a device information request to the first storage device, receive a device information response including device information of the first storage device from the first storage device in response to the device information request and update the first inventory information table with the device information of the first storage device.

Abstract: Methods, systems, and computer programs encoded on computer storage medium, for identifying a data storage environment including a plurality of disk drives; exposing for each of the disk drives of the data storage environment, a management interface of the disk drive to create a zero-capacity device for the disk drive; identifying a management command for a particular disk drive of the plurality of disk drives; identifying a particular zero-capacity device that corresponds to the particular disk drive; providing the management command to the particular zero-capacity device; and in response to providing the management command, receiving a response from the particular disk drive, the response including a processing result that is responsive to the management command.
