Architecture of EMC Unity Hybrid Flash Systems
Underlying Mechanisms
The core architecture of Unity Hybrid Flash systems includes dual storage processors that handle data and control operations. This setup enhances system availability and performance by ensuring that each processor can independently manage workloads, reducing the risk of bottlenecks.
Data Flow and Storage Efficiency
- Data enters the system through a configurable mix of FC, iSCSI, and Ethernet interfaces.
- Utilizes both SSDs and HDDs for tiered storage, automatically moving frequently accessed data to faster SSD media.
- Inline compression and deduplication reduce the data footprint, allowing efficient utilization of storage capacity.
- Snapshots are created without affecting performance, providing point-in-time copies for backup and recovery operations.
Comparisons with Competing Technologies
EMC Unity vs Pure Storage FlashArray
- Cost Efficiency: EMC Unity offers a more cost-effective solution due to its hybrid model, whereas FlashArray focuses on all-flash performance.
- Data Services: Both offer robust data services, but EMC Unity has an edge with its versatility in handling multiple types of IO workloads.
EMC Unity vs HPE Nimble Storage
- Integration: While both systems support hybrid configurations, EMC Unity provides stronger VMware integration, which is beneficial for environments heavily reliant on virtualization.
- Management and Monitoring: Unity’s reliance on Dell EMC Unisphere provides advanced analytics and easier management compared to HPE’s InfoSight.
