Technical Architecture
EMC Unity All-Flash storage is designed on a modern, multi-core processing platform with a comprehensive suite of automated storage management features. This versatility allows Unity systems to perform efficiently in various high-demand environments.
Component Breakdown
| Component | Description |
|---|---|
| SP – Storage Processor | The core processing unit equipped with multi-core CPUs that handle I/O operations and data services. |
| SSD – Solid State Drives | Fast, reliable flash storage devices configured in RAID arrays for data redundancy. |
| Memory | High-speed DRAM and NVMe used for caching and buffering I/O requests. |
| Unisphere Management | Centralized storage management platform with an intuitive interface as well as RESTful API support. |
Data Flow Mechanism
Data flow in Unity starts when a client sends an I/O request, which is captured and processed by the Storage Processor (SP). Below is a detailed explanation of the process:
- The SP receives I/O requests and immediately writes small units of data to its DRAM, enhancing speed while waiting for the SSDs to persist the data.
- Data is deduplicated and compressed inline before being stored, an essential step in optimizing storage space and cost-efficiency.
- RAID protection is applied, distributing data across SSDs to prevent data loss due to drive failures.
- Fast Cache and Dynamic Caching ensure frequently accessed data is available in low-latency memory, reducing read times.
- Management processes are handled by Unisphere, which provides visibility and control over system operations, including performance analytics and troubleshooting.
Functionality and Benefits
Data Services and Automation
EMC Unity offers extensive data services, including replication, tiering, and snapshots, controlled through automation capabilities to streamline management:
- Replication: Synchronous and asynchronous replication options ensure business continuity and disaster recovery.
- Tiering: Auto-tiering moves cold data to more cost-effective storage within Unity or to cloud storage, optimizing resource use.
- Snapshots: Point-in-time copies allow businesses to quickly recover data without impacting performance.
Hybrid and Multi-Cloud Integration
Unity facilitates a seamless flow of data between on-premises and cloud environments, supporting hybrid and multi-cloud strategies. It supports platforms like AWS, Azure, and VMware Cloud for broader deployment options.
