Data Flow and Mechanisms
Data management in Unity All-Flash systems occurs via a multi-layered architecture comprising storage pools, LUNs or file systems, and services.
- Storage Pools: Logical collections of drives allocating space across their members for workloads.
- LUNs/File Systems: Data containers created within pools, either as block-level LUNs or file-based systems.
- Data Services: Snapshot capabilities, replication, and other services such as tiering, dynamically manage workloads.
Advanced Data Management Features
Data Reduction
Unity All-Flash utilizes in-line data reduction techniques:
- Compression: Reduces sizes of files and block data, contributing to lower storage costs.
- Deduplication: Identifies and reduces duplicate data sets seamlessly.
Replication and Backup
Replication features ensure data availability and disaster recovery:
- Supports asynchronous replication.
- Enables remote replication for file and block data.
- Leverages native snapshot technology for granular recovery points.
