Data Flow and Functionality
Data Flow Mechanism
The EMC Unity All-Flash system uses a sophisticated data path architecture to manage data efficiently across its storage resources:
- Data Ingestion: High-speed interfaces support rapid data ingestion from a variety of sources, aided by caching mechanisms to manage initial input burst loads effectively.
- Data Distribution: Once data is ingested, it is uniformly distributed across available SSDs/NVMes to optimize performance and redundancy using proprietary algorithms.
- Data Management: Includes inline data reduction techniques like compression and deduplication to optimize storage usage.
Underlying Mechanisms
- Dynamic Pools: Enable flexible resource allocation and rebalancing of workloads with minimized admin intervention.
- Snapshot and Replication: Unity systems provide robust snapshot and replication capabilities for data protection and disaster recovery purposes.
