• Data Efficiency: Inline data reduction techniques such as compression and deduplication to maximize storage efficiency.
• Scalability: Capability to scale up with additional drives and scale-out with additional nodes.
• Ease of Use: User-friendly management interface and integration with cloud-based monitoring tools.

Technical Specifications

Architecture and Functionality

The EMC Unity architecture is built around delivering consistent performance for mixed workloads by integrating a combination of enterprise-grade SSDs with a multi-core processing infrastructure. Detailed below is the data flow and core mechanisms that make this possible.

Data Flow

1. Data Input: Data is received via host connectivity options such as Fibre Channel, iSCSI, or NAS protocols.
2. Data Reduction: Inline deduplication and compression are applied to minimize data footprint, optimizing storage efficiency.
3. Data Management: Automated tiering ensures active data resides on the highest-performing storage tier (NVMe or SAS flash).
4. Data Access: Advanced caching algorithms ensure data is readily accessible, leveraging DRAM and SSD cache layers.
5. Data Protection: Data is safeguarded with integrated solutions like snapshots, replication, and encryption.

Underlying Mechanisms

• SP Cache: The Storage Processor (SP) cache is used to store metadata and host write operations, enhancing system response times.
• FAST VP (Fully Automated Storage Tiering for Virtual Pools): Implementing automated data migration across storage tiers optimizes both performance and cost.
• RAID Protection: Implements hybrid RAID levels such as RAID 5 and RAID 6, enhancing data protection while maintaining performance.
