Abstract: A computer system includes a NoSQL/SQL cluster and a distributed storage. In order to make storage target data redundant, a compute node in the NoSQL/SQL cluster instructs other compute nodes in the NoSQL/SQL cluster to write the storage target data into the distributed storage.

The distributed storage performs erasure coding to store a file of the storage target data newly found to be duplicate in deduplication and to store a file of the storage target data not deduplicated in deduplication.

Abstract: A backup-source storage system extracts, as a pattern, forwarding target data to a backup-destination storage system among data written to a storage apparatus through a volume. The backup-source storage system determines whether the extracted pattern matches with a registered pattern in the backup-source storage system. When a result of the determination is false, the backup-source storage system registers the extracted pattern and forwards the forwarding target data to the backup-destination storage system. When the result of the determination is true, the backup-source storage system does not forward the forwarding target data.

Abstract: A plant control system and communication method are capable of immediately dealing with wrong address settings created due to a human error during the execution of an opening procedure. In the plant control system, a higher-level device and a plurality of communication terminal devices are connected to each other through a communication path. Prior to the start of communication, a communication opening process of sequentially transmitting a call signal from the higher-level device to the terminal devices and acknowledging response signals therefrom is executed, which is followed by sequentially transmitting a call signal from the higher-level device to the terminal devices and receiving response signals from the terminal devices. The communication terminal devices compare addresses of the response signals returned from the other terminal devices to the higher-level device against an address set for local terminal devices. If a duplicate address exists, communication from the local terminal device is locked.
