9.3.5 Parallel Access Volumes (2244 Model PAV)
The Parallel Access Volumes model and features establish the extent of IBM authorization for
the use of the Parallel Access Volumes licensed function.
Table 9-8 provides the feature codes for the PAV function. (The codes apply to models
921,922, and 9A2.)

9.3.6 Ordering licensed functions
An OEL is required for every DS8000 base unit. This license is for the total physical capacity
of the entire storage unit, including the base and any expansion models, and for both FB and
CKD data, but excludes Standby CoD disk drives. For example, if the total capacity of the
storage unit is 30 TB (15 TB in the base frame and 15 TB in the expansion frame), then you
will purchase an OEL feature for 30 TB.
Should you increase your capacity in the future, for example, from the 30 TB to 40 TB,
whether you are using Standby CoD disk drives or additional disk drives, you then must
purchase an additional 10 TB of 2244 Model OEL features.
The other optional features such as PTC, RMC, RMZ, and PAV can use any combination of
the features to cover the required capacity of the storage unit. For example, if the storage unit
has a capacity of 20 TB of data and only 5 TB of the data will be PTC, then you only need to
purchase a PTC license for 5 TB of data – not the full 20 TB.
Figure 9-4 shows an example of a FlashCopy feature code authorization. In this case, the
user is authorized up to 25 TB of CKD data. The user cannot FlashCopy any FB data.
