Storage Design for Business Continuity

Storage High Availability

  • Purpose of storage high availability is business continuity and/or disaster recovery. This is used to prevent one or more failures of hardware or software resulting in data loss.

  • The common understanding of storage high availability is redundancy within a cluster of servers when viewed from a server centric aspect and cluster of storage array units from a storage centric view.

  • Storage High Availability can be viewed from these aspects:

    • Multiple servers accessing single storage devices
    • Storage Arrays mirroring across multiple frames or within a single frame.
    • Single or multiple servers accessing multiple storage devices.
  • Each of these aspects of High Availability can be found within the Mt Xia environment or that of its clients
