Storage Design for Business Continuity

Storage Disaster Recovery

  • Purpose of storage disaster recovery is driven by business requirements. This is used to prevent one or more failures of hardware or software resulting in data loss at a site to site level.

  • The common understanding of storage disaster recovery is redundancy between sites for servers and storage arrays.

  • Storage Disaster Recovery can be viewed from these aspects:

    • Multiple servers replicating single storage devices across multiple sites.
    • Multiple servers replicating transaction changes across multiple sites.
    • Storage Arrays replicating across multiple frames across diverse locations. (Site to Site replication)
  • Replication can be synchronous or asynchronous

  • Each of these aspects of Disaster Recovery can be found within the Mt Xia environment or that of its clients
