IBM DS8000 Metro Mirror Disaster Recovery Within a Remote Cluster
Disasters can happen at any time, in any place, with or without warning. The data loss to a business can be so drastic that it can no longer operate. One must always plan for disaster. In answer, IBM provides an integrated real-time disaster recovery solution that combines IBM Metro Mirror replication and third-party clustering within and across geographically separated data center. As a two-site synchronous replication solution, Metro Mirror is ideal for protecting data against a storage system outage or complete site failure. This paper is to provide an overview of an IBM Metro Mirror solution in a remote area, combined with supporting clustering method Symantec Veritas Cluster.
