Abstract
Methods and apparatus for performing Storage Media Encryption (SME) are disclosed. In one embodiment, an apparatus includes a memory and a plurality of processors. The apparatus receives a write command from a network device. The apparatus sends a transfer ready to the network device in response to the write command. The apparatus receives data from the network device. The apparatus composes a status and sends the status the network device. The status is sent to the network device after the data has been received from the network device and prior to both compressing and encrypting the data. The apparatus compresses the data to generate compressed data. One of the plurality of processors encrypts the compressed data to generate modified data. The apparatus then sends the modified data to a target indicated by the write command.
