RAID-6 Recovery Case - PITS Global's expertise in recovering data from RAID-6 setups

In the world of data storage and management, RAID configurations have long been a cornerstone of ensuring data reliability, availability, and performance. Among the many RAID levels available, RAID 60 stands out as a powerful and versatile option that combines the benefits of multiple RAID 6 arrays to create a robust, high-performing storage solution. 

In this blog, we delve into the world of RAID 60, exploring its features, benefits, and considerations for implementation.

Understanding RAID Basics

Before diving into RAID 60, let us briefly recap what RAID is. RAID, which stands for Redundant Array of Independent Disks, is a technology that involves grouping multiple physical hard drives into an array to improve data performance, reliability, and fault tolerance. 

Different RAID levels offer varying combinations of these attributes to meet specific requirements. For instance, RAID 0 enhances performance but lacks redundancy, while RAID 1 provides full redundancy at the cost of storage efficiency.

The Essence of RAID 6

RAID 6, the foundation of RAID 60, is known for its exceptional data redundancy capabilities. It utilizes a block-level striping technique, spreading data across multiple disks and generating dual parity information distributed across the drives. This means that data integrity is maintained even if two drives in the array fail simultaneously.

Introducing RAID 60

RAID 60 is a nested RAID configuration that combines the best aspects of RAID 6 and RAID 0. It is essentially a RAID 0 array striped over several RAID 6 arrays. This hybrid setup is designed to offer enhanced redundancy and impressive performance. 

In RAID 60, data is striped across multiple RAID 6 arrays, delivering the redundancy and fault tolerance of RAID 6 while capitalizing on the speed advantages of RAID 0.

Benefits of RAID 60

1. High Fault Tolerance. RAID 60 inherits the robust fault tolerance of RAID 6. Even if multiple drives fail within a RAID 6 array, the secondary parity data ensures that data can be reconstructed without any loss. Furthermore, the additional redundancy provided by RAID 60’s nested structure adds another layer of security against data loss.

2. Optimized Performance. By employing RAID 0 striping across multiple RAID 6 arrays, RAID 60 achieves excellent read and write performance. This makes it suitable for applications that demand both speed and reliability, such as large-scale databases and high-traffic servers.

3. Scalability. RAID 60 allows for easy expansion by adding more RAID 6 arrays to the configuration. This scalability ensures that storage capacity and performance can be adjusted as business needs evolve.

4. Cost-Effective. While RAID 60 requires a larger number of drives due to its nested structure, it still offers a good balance between cost and performance. For organizations requiring both performance and redundancy, the investment in additional drives can be justified by the benefits gained.

5. Versatility. RAID 60’s blend of performance and reliability suits a wide range of applications. From enterprise-level data centers and virtualization environments to video production and surveillance storage, it can accommodate various workloads effectively.

Considerations for Implementation


While RAID 60 is undoubtedly a compelling option, its implementation requires careful planning and consideration:

1. Drive Selection. Choose high-quality enterprise-grade drives with a low risk of failure. The more drives you have in the array, the higher the probability of encountering drive failures, so selecting reliable components is crucial.

2. Controller Performance. The RAID controller plays a significant role in the overall performance of a RAID 60 array. Ensure that the controller can handle the increased complexity of managing multiple RAID 6 arrays and RAID 0 striping.

3. Backup and Monitoring. Despite its robustness, RAID 60 doesn’t replace the need for regular backups. Also, implement thorough monitoring and alerting mechanisms to promptly address any drive or array issues.
4. Initial and Ongoing Costs. RAID 60 requires a larger number of drives, which can result in higher initial costs. Additionally, ongoing maintenance and replacement costs should be factored into the decision.
5. Configuration Expertise. Setting up and managing RAID 60 arrays might require a higher level of technical expertise. If your IT team is not experienced in complex RAID configurations, consider seeking professional assistance.

RAID 60 is a compelling storage solution that merges the redundancy and fault tolerance of RAID 6 with the performance benefits of RAID 0. This makes it an excellent choice for businesses and organizations that demand both speed and data integrity.
By understanding its features, benefits, and implementation considerations, you can make an informed decision about whether RAID 60 is the right fit for your specific storage requirements. Just remember, like any technology, RAID 60 is a tool, and its success in your environment depends on how well it aligns with your needs and infrastructure.

Frequently Asked Questions

RAID 60 is a nested RAID configuration that combines the characteristics of RAID 6 and RAID 0. It offers the redundancy and fault tolerance of RAID 6 while leveraging the performance advantages of RAID 0. This makes RAID 60 suitable for applications requiring both speed and data integrity.

RAID 60 is a great choice for scenarios where both high performance and data protection are essential. It’s suitable for applications such as large-scale databases, virtualization environments, video editing, and surveillance storage, among others.

RAID 60 combines the strengths of RAID 6 and RAID 0, offering high fault tolerance, optimized performance, scalability, cost-effectiveness, and versatility. This makes it an attractive option for environments where performance and data protection are critical.

Setting up RAID 60 requires a solid understanding of RAID concepts and configuration. It’s recommended to have experienced IT personnel handle the setup, ensuring the array is correctly established to provide the desired performance and redundancy benefits.

Migrating from one RAID level to another can be complex and risky. If you’re considering migrating to RAID 60, it’s best to consult with storage professionals who can evaluate the feasibility and guide you through the process safely.

RAID 60’s dual parity across multiple RAID 6 arrays ensures that even if multiple drives fail concurrently, data integrity is preserved. The secondary parity data can be used to rebuild the lost data without compromising the array’s reliability.

It’s possible to use drives of different sizes in a RAID 60 setup. However, it’s crucial to remember that the array’s overall capacity will be limited by the size of the smallest drives, and performance might not be optimized if drive sizes vary significantly.
