Key Features

Equallogic controller modules come equipped with a variety of advanced features designed to enhance the functionality, performance, and reliability of your storage solution.

Advanced Data Management

Equallogic controller modules offer advanced data management features, including:

• Automated Tiering: Automatically moves data between high-performance and high-capacity storage tiers based on access patterns, improving efficiency and cost-effectiveness.
• Thin Provisioning: Dynamically allocates storage space as needed, reducing wasted capacity and improving overall storage efficiency.
• Snapshots and Cloning: Offers advanced backup and recovery options by taking point-in-time snapshots and creating instant clones of volumes for testing or backup purposes.

High Availability and Redundancy

One of the most crucial aspects of controller modules is ensuring data availability even during failures. Equallogic controller modules achieve this through several mechanisms:

• Dual Controllers: In high-demand environments, using two controllers in an active-passive or active-active configuration ensures failover in case one controller fails, reducing downtime.
• Redundant Power Supply: Most Equallogic systems feature dual power supplies, providing protection against power failures and enhancing system stability.
• Hot Swappable Components: In case of hardware failure, users can replace faulty modules or disks without needing to shut down the entire system.

Redundant Data Paths

Equallogic controller modules support multiple data paths, ensuring that there is always an active path to data, even if one path becomes unavailable. This redundancy improves overall performance and ensures reliability in a mission-critical environment.

Performance and Scalability

Equallogic controller modules are engineered to deliver consistent, high performance, even in demanding workloads. Some key factors contributing to their performance include:

• High-Speed Networking: These modules support high-speed Ethernet and Fibre Channel connections, ensuring fast data transfers between storage and host systems.
• Multi-Core Processing: Equipped with multi-core processors, the controller modules can handle multiple tasks simultaneously without compromising performance.
• Cache Memory: Equipped with large amounts of cache memory, Equallogic controller modules speed up data access by storing frequently accessed data.

Compatibility and Integration

Equallogic controller modules are designed to integrate seamlessly with other Equallogic components, such as storage arrays and disk enclosures, offering a complete, optimized storage solution. The modular design ensures compatibility across a wide range of Equallogic systems, enabling customers to scale their storage infrastructure according to their needs.

Compatible Disk Enclosures

Equallogic controller modules work efficiently with various disk enclosures, allowing you to configure a system that matches your performance and storage needs. Whether you require high-density storage or need to prioritize speed, the combination of controller modules and disk enclosures provides a flexible solution.

Interoperability with Host Systems

Equallogic controller modules are compatible with a broad range of host systems and operating environments, including Windows, Linux, and VMware. They can be easily integrated into existing infrastructures, enabling organizations to enhance their storage capabilities without significant changes to their IT environment.

Upgrading Your Equallogic Controller Module

Upgrading or replacing an Equallogic controller module is often an essential part of maintaining your storage system’s performance and reliability. The process typically involves:

• Planning the Upgrade: Before replacing a controller module, ensure compatibility with your existing storage components and systems.
• Backup: Always perform a backup of your critical data before proceeding with an upgrade.
• Installation: Most Equallogic systems feature hot-swappable components, allowing users to replace or upgrade controller modules without shutting down the system.

Replacing a Faulty Controller Module

If a controller module fails, it’s essential to replace it quickly to minimize downtime. Equallogic provides easy-to-follow instructions for replacing failed modules, and most systems support hot swapping, meaning you can replace the component without disrupting the ongoing operations of the system.
