EMC Unity All-Flash Architecture
The architecture of EMC Unity All-Flash storage is built upon a robust foundation to meet the demands of modern, data-driven applications.
| Component | Description |
|---|---|
| Dynamic RAID | Leverages RAID 5/6 to protect against data loss while maintaining optimal speed and capacity utilization. |
| Multiprotocol Support | Provides support for block (iSCSI, FC) and file (NFS, SMB) data access services. |
| Advanced Data Reduction | Includes inline deduplication and compression to improve storage efficiency. |
Data Flow and Underlying Mechanisms
The data flow within EMC Unity All-Flash storage begins when data is first ingested through supported protocols. The data passes through an inline deduplication process that eliminates redundant data repeatedly.
Subsequently, the unified cache system temporarily holds the data for faster read and write operations, ensuring low latency and high-throughput data access. The sophisticated RAID protection scheme safeguards the data from hardware failures.
Data-at-rest encryption applies as soon as data reaches storage, securing sensitive information with minimal impact on performance. The system uses 256-bit Advanced Encryption Standard (AES) to protect data, adhering to stringent compliance requirements.
Comparison with Competing Technologies
Competing Technology: HPE Nimble Storage
HPE Nimble Storage offers comprehensive analytics with its InfoSight Predictive Analytics, but it lacks the multiprotocol support inherent in EMC Unity All-Flash Systems.
| Feature | EMC Unity All-Flash | HPE Nimble Storage |
