HPE MSA2060 Storage Terrible Performance Drop ..... and even Web Console no response

 Q. When config HPE msa2060 storage auto-tiering function, should I reserve some space for auto-tiering ?

Ans :

Yes, when configuring auto-tiering on an HPE MSA 2060 storage system, it's a good practice to reserve some space for the auto-tiering functionality. This helps ensure that the system has sufficient resources to efficiently manage and move data between different tiers based on usage patterns and performance requirements. The specific amount of space to reserve can vary based on your workload, data types, and performance needs. It's advisable to consult HPE's documentation or work with their support to determine an appropriate allocation for auto-tiering.

Q. Any suggestion for how much space should I reserve?

The amount of space you should reserve for auto-tiering on your HPE MSA 2060 storage system can vary based on several factors, including: 

Data Patterns: Analyze your data access patterns to understand how frequently and intensively data is accessed. Frequently accessed data may need a larger tier to ensure optimal performance.

Data Size and Growth: Consider the size of your data and how it is expected to grow over time. Allocate space that accommodates future growth and scaling needs.

Performance Requirements: Evaluate the performance requirements of your applications. Critical and performance-sensitive applications may require a larger allocation to ensure optimal performance.

Workload Type: Different workloads (e.g., database, file storage, virtual machines) have varying storage needs. Tailor the reservation based on the types of workloads you are supporting.

Resiliency and Redundancy: Account for redundancy and resiliency requirements, ensuring that there's ample space to handle mirrored or redundant copies of data.

Recommendations from HPE: Refer to HPE's official documentation or consult their support for specific recommendations regarding auto-tiering space allocation.

A common practice is to reserve around 10-20% of the total storage capacity for auto-tiering purposes. However, it's essential to review and adjust this based on your unique circumstances and the factors mentioned above. Additionally, consider monitoring the system's performance and adjusting the allocation as needed to maintain optimal performance over time.
