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.
