Abstract
A first storage system of a remote copy system includes a data volume, a journal volume, and a storage controller. When an operation is received from a first server system, based on the operation, the storage controller executes any of a work of storing the update content by the operation in the journal volume or a work of executing the operation when the operation is received.
Claims6
A remote copy system comprising:
- a primary site including a first server system and a first storage system connected to the first server system;
- and
- a secondary site including a second server system and a second storage system connected to the second server system, wherein
- the first server system and the second server system are clustered,
- a virtual storage system is configured by the first storage system and the second storage system,
- an asynchronous remote copy is performed with the first storage system as a copy source and the second storage system as a copy destination,
- the first and second storage systems are configured to detect a failure of the second or first storage system that is a destination of the asynchronous remote copy,
- the first storage system includes a data volume, a journal volume, and a storage controller, and
- when an operation is received from the first server system, based on the operation, the storage controller executes any of a work of storing update content by the operation in the journal volume or a work of executing the operation after the operation is received;
- wherein the storage controller reflects the update content stored in the journal volume on the second server system after a failover occurs at the primary site and determines which work is executed based on a type of the operation.
