text: **11.10 Remote Copy memory allocation**
  
  Copy Services features require that small amounts of volume cache be converted from cache 
  memory into bitmap memory to allow the functions to operate at an I/O group level. If you do 
  not have enough bitmap space allocated when you try to use one of the functions, the 
  configuration cannot be completed. 
  
  The total memory that can be dedicated to these functions is not defined by the physical 
  memory in the system. The memory is constrained by the software functions that use the 
  memory.
