Abstract: A high-availability computer system includes a plurality of computer nodes for parallel data processing, wherein each computer node has at least one data processing component and a main memory. The computer system furthermore includes a plurality of storage nodes, wherein each storage node has at least one non-volatile mass storage device. The plurality of computer nodes are partitioned into a plurality of computer groups, wherein each of the plurality of computer groups has at least one redundant computer node. Each computer group has a local connection structure allocated to the respective computer group, the structure connecting the storage nodes allocated to the respective computer group to the computer nodes of the respective computer group.

Abstract: A highly available main memory database system includes a plurality of computer nodes, including at least one computer node that creates a redundancy of the database system. The highly available main memory database system further includes at least one connection structure that creates a data link between the plurality of computer nodes. Each of the computer nodes has a synchronization component that redundantly stores a copy of the data of a database segment assigned to the particular computer node in at least one non-volatile memory of at least one other computer node.
