Abstract: A system and method for providing erasure code protection across multiple storage devices. A data switch in a storage system connects a plurality of storage devices to a remote host. Each storage device is also connected to a controller, e.g., a baseboard management controller. During normal operation, read and write commands from the remote host are sent to respective storage devices through the data switch. When a write command is executed, the storage device executing the command sends a copy of the data to the controller, which generates and stores erasure codes, e.g., on a storage device that is dedicated to the storage of erasure codes, and invisible to the remote host. When a device fails or is removed, the controller reconfigures the data switch to redirect all traffic addressed to the failed or absent storage device to the controller, and the controller responds to host commands in its stead.

Abstract: A storage device configured for hardware verification is disclosed. The storage device comprises a first hardware component comprising a connector and a first verification logic. The first validation logic is configured to detect a criterion and generate a first signal via the connector in response to detecting the criterion. The storage device also comprises a second hardware component coupled to the first hardware component via the connector. The second hardware component comprises a second validation logic, where the second validation logic is configured to monitor and receive the first signal via the connector. In response to receiving the first signal, the second validation logic is configured to compare the received first signal to an expected signal and generate a result. The storage device is configured to take an action in response to the result.

Abstract: A system and method for power distribution are disclosed. A processor detects a storage device having a scalable interface, where the scalable interface is for transferring data between a host device and the storage device. The processor determines power requirement of the storage device based on a signal from the scalable interface. At least one power supply unit coupled to the processor provides power to the storage device based on the determined power requirement.
