Is this a system, application, or tool?
zDMF is a tool set designed to address data migration challenges within the z/OS environment. It provides the functionality needed to move datasets between storage subsystems efficiently and non-disruptively.
What types of organizations use this?
Organizations that rely on z/OS mainframes and need to perform data migrations or upgrades without downtime are ideal candidates for zDMF. This includes enterprises in industries such as banking, finance, insurance, and government.
When should we consider zDMF?
A company should consider using zDMF when planning a storage subsystem upgrade, consolidating data centers, or needing to balance workloads across different storage tiers. It is particularly useful when minimizing downtime during these activities is critical.
What are the alternatives to zDMF?
Alternatives to zDMF include TDMF (also from IBM), which operates at the volume level, and other data replication or migration tools. The key difference is that zDMF operates at the dataset level, providing more granular control.
