IBM System Storage DS6000 Series: Copy Services with IBM System z
8.1  Ordering FlashCopy
FlashCopy is an optional licensed function of the IBM System Storage DS6000 series. This 
function is also referred to as the Point-In-Time Copy (PTC) licensed function
All DS6000 series licensed functions are enabled, authorized, managed, activated, and 
enforced based upon the physical capacity contained in a 1750 system.
Enablement
This refers to the purchase of a feature number to technically activate the associated licensed 
function. Each licensed function is 
enabled
 for a 1750 system through acquiring the 
corresponding feature numbers. 
Particularly for FlashCopy, the 1750 feature that must be ordered is the Point-in-Time Copy 
(PTC) licensed function, feature #52xx; see Table 8-1.
Table 8-1   FlashCopy features
Each licensed function feature number purchased for a 1750 machine enables that function 
for the entire 1750 system.
Authorization
This refers to the purchase of a feature number to establish the extent of IBM 
authorization
 
—license size in terms of physical capacity— for use of an associated licensed function. This 
is also referred to as the 
authorization level
.
The extent of IBM authorization for the use of a licensed function on a 1750 system is 
established by acquiring an 52xx feature number on the 1750 base enclosure. The same 
52xx feature numbers acquired to enable a licensed function also establish the extent of 
IBM's authorization.
The 52xx feature number on a 1750 base enclosure establishes the authorization level for the 
entire 1750 system. For example, a 1750 system with a Model 522 base enclosure and two 
Model EX2 expansion enclosures requires the acquisition of 52xx feature numbers only on 
the Model 522. Therefore, for licensed functions authorized on the basis of physical 
capacity—as in the case of PTC—the authorization level established with the acquisition of 
the 52xx feature number on the Model 522 must also cover the physical capacity of the 
attached Model EX2 expansion enclosures.
Note: For a detailed explanation of the features involved and the factors to be considered 
when ordering FlashCopy we recommend you refer to the IBM System Storage DS6000 
Series (IBM 1750-522) announcement letter.
