摘要: HypRa is a database server designed to meet extreme requirements from e.g. telecom applications. Fault-tolerance has been into by: (1) taking it account at all hard-ware and software levels, (2) using shared-nothing, coarse grained hardware platform with homogeneous nodes, basic fault detection, multiway interconnection network dynamic rerouting, (3) doing masking repair in achieve flexibility reconfigurability, (4) data fragmentation, fragment replication replica allocation, reconfiguration automatically reproduce the availability fault-tolerance level. >
