As far as IBM DS8000 is concerned, if you have Flashcopy, you also have Metro Mirror (PPRC), as both are part of the Copy Services (CS) feature. In fact, here are the function in each license type: Base function License (BF) ? Operating Environment License ? Logical Configuration support for FB (Open Systems) ? Thin Provisioning ? Easy Tier ? I/O Priority Manager Copy Services License (CS) ? IBM FlashCopy® ? Metro Mirror ? Global Mirror ? Metro/Global Mirror ? z/Global Mirror ? z/Global Mirror Resync ? Multi-Target PPRC z-Synergy Services License (zsS) ? FICON attachment ? PAV ? HyperPAV ? High-performance FICON (zHPF) ? IBM z/OS Distributed Data Backup To me, it's simpler and more cost-effective to get GDPS. The configurations include local HA with Hyperswap and flashcopy images (with zero data loss and no down time), as well as remote copy (Global Mirror) along with flashcopy images to allow DR testing while still maintaining local and remote HA. The important thing is that YOU don't support it. (Care and feeding of disk mirrors is not trivial.) ICKDSF and the CP FLASHCOPY family of commands are the only native functions in z/VM that manage Copy Services. I wish we had Copy Services Manager (CSM) for the CMS environment.
