Hitachi intelligent storage control systems can be used to lower the cost of storage connected to a mainframe in an IBM z/OS environment by allowing lower cost midrange (SATA) and other open systems storage to be used for applications that have Tier 2 or Tier 3 performance and availability requirements. Controller-based storage virtualization is able to provide z/OS mainframe connectivity to both enterprise and midrange storage platforms, some of which can be configured with lower cost SATA drives. This also allows organizations to further extend the life of existing storage assets, including storage from a variety of other vendors and potentially reduce costs.
