摘要:
Data versioning in a non-volatile memory. An object key associated with a data object is created. An index into an object table is generated using the object key. A version number is stored in conjunction with the data object stored in the non-volatile memory. In an object linked-list, the object key and the location information of the data object in the non-volatile memory are stored. A record associated with the data object is created in an object table. The record includes an index, a reference to the object linked-list, and the version number. The index is generated based on the object key.
摘要:
Data replication in a distributed node system including one or more nodes. A consensus protocol for failure recovery is implemented. Data items and information relating to consensus protocol roles of participant nodes are stored in at least some of the plurality of nodes. Logical logs stored in at least some of the plurality of nodes are created. The logical logs contain additional consensus protocol information including container metadata and replicated data.

Approaches for a distributed storage system that comprises a plurality of nodes. Each node, of the plurality of nodes, executes one or more application processes which are capable of accessing persistent shared memory. The persistent shared memory is implemented by solid state devices physically maintained on each of the plurality of nodes. Each the one or more application processes, maintained on a particular node, of the plurality of nodes, communicates with a shared data fabric (SDF) to access the persistent shared memory. The persistent shared memory comprises a scoreboard implemented in shared DRAM memory that is mapped to a persistent storage. The scoreboard provides a crash tolerant mechanism for enabling application processes to communicate with the shared data fabric (SDF).

The invention provides technology that improves the security of the A-Keys in a wireless communications system. The technology effectively prevents any human access to the A-Keys and eliminates cloning. The invention improves the security and integrity of the wireless communications system. A secure processor exchanges random numbers with a wireless communications device to generate the A-Key. The secure processor then encrypts the A-Key and transfers the encrypted A-Key to an authentication system. When the authentication system generates or updates the SSD, the authentication system transfers the encrypted A-Key and other information to the secure processor. The secure processor decrypts the A-Key and calculates the SSD. The secure processor transfers the SSD to the authentication system for use in authenticating the wireless communications device.
