EMC Unity All-Flash Architecture Overview

The architecture underlying EMC Unity All-Flash arrays is designed to deliver consistent high-speed data access and storage. The system uses Non-Volatile Memory Express (NVMe) for efficient data transfer between flash storage media and system processors. This section delves into the core components and structures that define the architecture.

Storage Processors

EMC Unity utilizes dual-active storage processors (SPs) to manage I/O operations efficiently. Each SP is equipped with multiple cores, providing parallel processing capabilities that enhance throughput and minimize latency.

Dynamic Pools

Dynamic pools in Unity arrays allow for dynamic performance tuning and flexible allocation of storage resources. This flexibility in storage provisioning results in efficient space usage and reduced overhead.

Data Services

Unity offers a comprehensive suite of data services, including snapshots, replication, encryption, and tiering. These services are accessed through a Unisphere management interface, which allows seamless configuration and monitoring of storage resources.

Technical Specifications

Data Flow in EMC Unity All-Flash

The data flow architecture within Unity All-Flash operations ensures optimized data paths between network interfaces, storage processors, and flash drives. The NVMe protocol plays a crucial role in leveraging low-latency data transmission across these components, which is critical for sustaining the expected performance levels in high-demand environments. I/O operations are processed in parallel, with the data services layer facilitating seamless execution of snapshots and real-time replication for redundancy and data protection.
