IBM z/OS DFSMS Cloud Data Manager is z/OS software for migrating DFSMS Hierarchical Storage Manager (DFSMShsm) data from physical or virtual tape to cloud objects.
Migrating large amounts of existing DFSMShsm Migration Level 2 (ML2) data sets to Migration Level Cloud (MLC) enables you to:
- Reduce MSU consumption by avoiding the time-intensive recycle function, which is required for reading and rewriting aging data sets without gaps in the DFSMShsm environment.
- Directly access MLC data as compared to the serial access required for ML2 data, thereby eliminating contention issues that may arise when multiple applications try to access different data on the same real or virtual tape.
Learn how to install, configure and use the IBM z/OS DFSMS Cloud Data Manager.
Retain critical historical accuracy of data set while migrating data to cloud objects as the date last referenced and the migration date remain unchanged.
Leverage IBM Transparent Cloud Tiering to remigrate data to cloud objects with minimal z/OS host processing.
Tuning options enable you to migrate data sets to cloud without impacting DFSMShsm production workloads.
Cloud object storage gives you the flexibility to migrate DFSMShsm ML2 tape data to any S3-compatible object storage. You can leverage existing on-premise or off-premise cloud storage for storing cold data.
The TS7700 tape subsystem facilitates migration of DFSMShsm ML2 tape data to cloud objects, thereby reducing recycle processing time and replacing serial access with direct access to data.
Move vast amounts of cold data from tape to cloud object storage. Easily find and select DFSMShsm-managed ML2 tape data by last migration date to migrate from ML2 to MLC.
Create new policies or update existing policies defined years or decades ago for existing ML2 data. Use DFSMScdm to migrate existing ML2 data according to new or updated policies.
