Overview of EMC Unity All-Flash
EMC Unity All-Flash arrays offer a modern storage solution characterized by superior speed and simplified management. Designed to empower IT professionals with a powerful toolset that meets a variety of needs from performance to scalability, these arrays bring flash storage technology to new levels. The Unity All-Flash architecture is engineered for high performance, sophisticated reliability, and seamless integration with a wide range of enterprise environments.
Key Features
- Unified Storage: Supports block, file, and VMware Virtual Volumes (vVols) in one solution.
- All-Flash Performance: Optimized for SSDs to deliver low latency and high IOPS.
- Simplified Management: Intuitive, HTML5-based Unisphere interface aids in easy deployment and management.
- Data Services: Inline data reduction, data-at-rest encryption, and replication for data protection and efficiency.
- Scalability: Scales from small to medium enterprises with flexibility in configuration and capacity.
Architecture and Components
EMC Unity is built on the latest multicore x86 architecture and employs a dual-active controller setup for redundancy and performance optimization. The architecture ensures that all writes are mirrored to the peer storage processor for fault tolerance, while advanced caching techniques are used to accelerate reads.
| Component | Description |
|---|---|
| Storage Processors (SPs) | Two redundant controllers that handle processing and storage functions. |
| Flash Media | Uses SSD technology optimized for fast data access with low latency. |
| Unisphere | A centralized HTML5 management interface for configuring and managing the environment. |
Technical Specifications
- Drive Options: 1.92 TB, 3.84 TB, 7.68 TB, 15.36 TB SSDs.
- Maximum Raw Capacity: Up to 16 PB.
- Maximum IOPS: Span over 300k IOPS depending on drive configurations.
- Protocols Supported: FC, iSCSI, NFS, CIFS/SMB, and vVols.
Data Flow and Underlying Mechanisms
EMC Unity All-Flash arrays utilize advanced deduplication and compression techniques to optimize storage space utilization. Data flow within the system follows these key steps:
- Write IOs: Incoming write operations are cached in memory, reducing latency.
- Data Reduction: Writes are automatically deduplicated and compressed inline for optimal space usage.
- Data Mirroring: All data written is mirrored between the active storage processors to ensure integrity.
- Read IOs: Uses fast SSD caching to deliver near-instant response times for read operations.
