Storage Design for Business Continuity

First Previous Next Last

Storage - SAN

  • Current SAN environment utilizes Hitachi 9980s and 9585s within the midrange Unix environment. There is currently over 20 Terabytes within this environment.

  • The switch connectivity between storage arrays and systems are Cisco and Brocade.

  • The storage subsystems are managed and maintained by the Mt Xia Storage Management Group.

  • Each system utilizes redundant paths through the SAN fabric to provide high availability in the event of a hardware failure.

  • Disk mirroring is generally not done within the SAN environment.

  • Server based striping is not performed because the SAN environment is already performing this action.

  • The current direction is for all storage to reside on the SAN environment, including boot volumes.
