Abstract: Systems and methods are provided for a secondary authentication of a memory module. A nonce key is written to a nonce register of a register array on the memory module, the nonce register being accessible over two different interfaces.

Authentication information for use in performing authentication can be stored in an identification component on the memory module. If authentication is successful, the management system can generate the nonce key and write it to the nonce register. Upon receiving a request to access an address, a memory controller can read the nonce register of the memory module at the requested address and compare the nonce key to an identifier included in the request.

Abstract: Techniques are provided for storing immutable snapshot copes in write once read many (WORM) storage. A snapshot of a volume may be stored into one or more objects formatted according to an object format.
