text: Depending on the grain size of the FlashCopy mapping, the memory capacity usage is 
  different. One MiB of memory provides the following volume capacity for the specified I/O 
  group: 
  
  (cid:2) For clones and snapshots FlashCopy with 256 KiB grains size, 2 TiB of total FlashCopy 
  source volume capacity 
  
  (cid:2) For clones and snapshots FlashCopy with 64 KiB grains size, 512 GiB of total FlashCopy 
  source volume capacity 
  
  (cid:2) For incremental FlashCopy, with 256 KiB grains size, 1 TiB of total incremental FlashCopy 
  source volume capacity 
  
  (cid:2) For incremental FlashCopy, with 64 KiB grains size, 256 GiB of total incremental 
  FlashCopy source volume capacity 
  
  Review Table 11-9 to calculate the memory requirements and confirm that your system is 
  able to accommodate the total installation size.
