Abstract: This innovation provides a method for a networked and replicated database management system (DBMS) using only one-sided remote direct memory access (RDMA). Replicated databases retain some access to the stored data in the face of server failure. In the prior state of the art, after the software in the DBMS on one of the servers acted on a client's request to update the database, it would contact the other replicas of the database and ensure that they had recorded the change, before responding to the client that the transaction was complete. This innovation describes a method whereby the database client directly interacts with each DBMS replica over the network using only RDMA to directly modify the stored data while maintaining the properties of database atomicity and consistency. This method reduces transactional latency by removing any need for the server DBMS software to respond to or forward requests for service.

Abstract: A server is implemented within disk drive device or other drive device. The server-drive device may be used within a server tray having many disk drive devices, along with multiple other server trays in a cabinet of trays. One or more disk drive devices may be implemented in a server tray. The server-drive device may also be used in other applications. By implementing the server within the disk drive, valuable space is saved in a computing device.
