Provisioning in a mainframe environment involves configuring logical devices (LDEVs), mapping them to host systems, and managing performance and availability features to ensure reliability, scalability, and performance for mission-critical workloads. Hitachi Virtual Storage Platform One Block 85 (VSP One Block 85) provides advanced features such as Dynamic Provisioning and external virtualization that help administrators optimize resources while maintaining compatibility with IBM® z/OS® and other mainframe operating systems.
- LDEV creation and management
-
- Define and allocate LDEVs within the storage system.
- Assign subsystem IDs (SSIDs) and configure addressing schemas.
- Configure Extended Address Volumes (EAVs) such as 3390-A to handle large datasets.
- Volume provisioning
-
- Use Dynamic Provisioning for Mainframe to configure thin provisioning for mainframe volumes.
- Adjust provisioning as workloads evolve, including resizing or reassigning volumes.
- Security and access control
-
- Define host groups and map LDEVs to specific mainframe channels.
- Ensure secure access paths between storage and mainframe hosts.
- Control access to data using Volume Retention Manager.
