Bridging the Gap: Understanding the Benefits of EMC Unity Hybrid Flash for Business Growth

Overview of EMC Unity Hybrid Flash

EMC Unity Hybrid Flash, part of the broader Dell EMC Unity family, offers an adaptable storage solution designed to optimize business operations through reliable and scalable hybrid flash storage. With a focus on midmarket environments, Unity Hybrid Flash provides a versatile and cost-effective option that balances performance, capacity, and simplicity.

Key Features

• Unified Storage: Supports block, file, and VMware VVOLs in one system.
• Flash-Optimized Architecture: Leverages flash storage for more active data and hard disk drives (HDDs) for less active data.
• Simple Deployment: Offers an easy setup with a web-based interface.
• Advanced Data Services: Includes data protection and disaster recovery features.
• Scalability: Provides options for storage expansion and performance enhancements.
• Integration with Cloud: Supports cloud-enabled storage tiering through EMC CloudIQ.

Technology Architecture and Functionality

EMC Unity Hybrid Flash utilizes a combination of flash drives and HDDs to deliver optimized performance and cost-efficiency. The architecture includes the following components:

Storage Processors (SPs)

The Unity system includes dual SPs working in active-active mode to enhance throughput and ensure high availability. Each SP can handle multiple I/O operations, load-balanced across workloads.

Data Tiering

Unity’s data tiering mechanism automatically relocates frequently accessed data to flash storage, ensuring rapid access, while less active data resides on HDDs. This process employs machine learning algorithms to optimize storage efficiency.

Data Flow

Data access follows a streamlined path, beginning at the initiator level from servers, passing through SPs, and finally residing on the appropriate tier of storage drives. This flow is governed by the Quality of Service (QoS) policies to prioritize critical workloads.

Connectivity Options

• Unified Protocol Support: Provides iSCSI, NFS, SMB, and FC protocols over Ethernet and Fibre Channel networks.
• Integrated Replication: Syncs copies to local or remote sites for disaster recovery.
