HDS Dynamic Provisioning.
Thin provisioning for HDS VSP arrays enables over-provisioning of storage capacity with automated expansion, reducing wasted capacity and improving utilization rates.
Overview
HDS Dynamic Provisioning (DP) enables thin provisioning on Hitachi VSP storage arrays — allowing administrators to present more storage capacity to hosts than is physically allocated. Space is consumed from a shared pool only when data is actually written, dramatically improving utilization rates and reducing the need for over-provisioning.
STME implements Dynamic Provisioning as part of storage consolidation programs for GCC enterprises moving from siloed, over-provisioned storage environments to centrally managed thin-provisioned pools. DP integrates with HDS Tiered Storage Manager to automatically migrate data between storage tiers based on access patterns.
Key features
- Thin provisioning from shared storage pools
- Automated pool expansion and threshold alerts
- Zero-page reclaim to recover unused space
- Over-commitment of storage capacity to hosts
- Integration with HDS Tiered Storage Manager for auto-tiering
- Support for all VSP array models
