Storage Design for Business Continuity

First Previous Next Last


Storage - Virtual

  • Virtual Storage is storage presented to virtual I/O servers which in turn present this storage wholly or partially to a Virtual LPAR.

  • In this scenario Virtual I/O Servers act as the SAN or storage management subsystem in storage presentation to LPARs.

  • Virtual I/O Server is an AIX based platform that runs within an LPAR and is restricted to the Power 5 technology at this time.

  • Physical storage is presented to the Virtual I/O Server which in turn reallocates the storage to the virtual LPARs.

  • The Physical storage can be SAN, internal or external disks.

  • Virtual storage presentation is viewed by the virtual LPAR as a standard (virtual) SCSI drive.

  • The Virtual I/O Server can present entire disks or logical volumes as storage to a virtual LPAR.
