Storage Design for Business Continuity

First Previous Next Last

Storage - External SSA

  • SSA is direct attached storage and is currently utilized only in Non-HA environments.

  • SSA is utilized in development as well as production environments.

  • SSA provides multiple paths to an SSA disk and provides redundant loops to an SSA drawer to provide a Highly Available Disk subsystem.

  • SSA is currently not the desired direction of Mt Xia for its storage solutions and will be phased out as time passes.

  • There are currently only about 6 SSA drawers utilized within the Mt Xia environments.

For assistance with designing, implementing, and supporting your storage systems in a business continuity design structure, please contact Mt Xia.
