DASDPOOL—allocate data sets to DASD volume pools
Pools allow multiple volumes to be managed as single entities. Pools allow data sets to be grouped and managed by their characteristics. Pool storage groups are a key component of DFSMS.
Considerations in DASD pooling include the following:
- Use of storage versus private volumes
- Volume allocation for nonspecific requests
- Acceptance/rejection of requests for allocation on specific volumes
- Grouping of data sets by usage, by size, or by physical characteristics
Assignment of data sets to pools should be centrally controllable by the data center, without requiring JCL changes or any type of source changes. The storage administrator should be able to easily manage the storage of the entire organization.
DASDPOOL allows you to set standards for data sets’ volume residency. A collection of data sets, selected by filter and rule list parameters from a variety of job and data set properties, can be directed to reside on the volumes in a single pool or in multiple pools for more flexibility in space utilization and management.
