Abstract
A system including a baseboard management controller (BMC) and a storage device connected to the BMC, for dynamic protection of the storage device. The BMC includes a processor and a non-volatile memory storing a computer executable code. The computer executable code, when executed at the processor, is configured to: perform redirection of the storage device; receive a write protect command including write protect information of the storage device; extract the write protect information from the write protect command; store the write protect information in a data store of the non-volatile memory; and in response to receiving a write command to write data in the storage device, determine whether the data is writable to the storage device based on the write protect information stored in the data store. The data is written to the storage device only if it is determined that the data is writable to the storage device.
