In QuantaStor, the "Create Storage Tier" feature allows you to define and configure storage tiers within a storage pool. The purpose of this feature is to optimize storage performance and efficiency by grouping different types of storage media, such as solid-state drives (SSDs) and hard disk drives (HDDs), into separate tiers based on their characteristics and performance capabilities.


The main purposes and benefits of the Create Storage Tier feature in QuantaStor include:
In QuantaStor, the "Create Storage Tier" feature allows you to define groups of Storage Pools with similar properties.  For example, within a storage grid you may have several all-flash pools that are ideal for databases and VMs and several lower cost storage pools which are ideal for backup and archive workloads.


*Performance Optimization: By creating storage tiers, you can assign different types of storage media to specific tiers based on their performance characteristics. For example, you can designate SSDs for the high-performance tier, while HDDs can be assigned to a lower-performance tier. This allows you to allocate storage resources according to the performance requirements of your workloads, ensuring optimal performance for critical applications or data.
With Storage Provisioning Tiers those pools can be grouped together into a "Gold" provisioning tier for the all-flash storage and a "Silver" provisioning tier for the lower cost archive storage.  Once created all CLI/API commands which require a Storage Pool ID can be called using the ID of a Storage Provisioning Tier rather than a specific Storage Pool.


*Efficient Resource Utilization: Storage tiers enable efficient utilization of storage resources by matching the right storage media to the specific data access patterns and performance needs. Frequently accessed or performance-sensitive data can reside on the high-performance tier, while less frequently accessed or colder data can be stored on lower-performance tiers. This helps optimize storage costs by using higher-cost storage media judiciously and maximizing the overall storage efficiency.
The system will automatically choose the pool with the most free-space and will also take into account over-provisioning so that a fairly even balance can be achieved across pools.


*Automated Data Placement: QuantaStor's storage tiering feature includes automated data placement mechanisms. The system analyzes data access patterns and moves data between tiers based on its frequency of access. This ensures that frequently accessed data remains on the high-performance tier, while less frequently accessed data is automatically migrated to lower-performance tiers. Automated data placement optimizes performance and minimizes manual intervention in managing data placement.
The purpose of this feature is to make it easier for automated systems to provision storage from a QuantaStor storage grid without having to do complex analysis of the various pools in order to get a good match to a given workload's use case. Further, tiers can also contain location information so that the storage can be provisioned from systems local to the workload. For example, say your organization has a east-campus and a west-campus and a given workload requires high IOPS for a database.   It could provision from a tier named "east-campus-gold-tier" and QuantaStor will automatically determine which pool is the ideal one to provision from given the group of pools within the Storage Provisioning Tier "east-campus-gold-tier".  Similarly a user on west-campus needing archive storage could provision from "west-campus-silver-tier" to get low cost storage allocated for backups.
 
*Quality of Service (QoS): Storage tiers can be configured with specific Quality of Service settings to prioritize and allocate storage resources to different workloads or applications. By assigning QoS parameters to each tier, you can ensure that critical workloads receive the necessary storage resources and performance guarantees, preventing resource contention and ensuring consistent performance levels.
 
*Scalability and Expansion: The Create Storage Tier feature supports scalability and expansion by allowing you to add additional storage media to existing tiers or create new tiers within the storage pool. As your storage requirements grow, you can expand and adjust the storage tiers to accommodate increased capacity or incorporate new storage technologies.
 
*Simplified Management: QuantaStor's storage tiering feature provides a unified interface for managing and configuring storage tiers within a storage pool. This simplifies storage management tasks by providing a consolidated view of the storage resources, their performance characteristics, and automated data movement between tiers. Administrators can easily monitor and adjust tiering settings to align with changing workload requirements.
 
Overall, the purpose of the Create Storage Tier feature in QuantaStor is to optimize storage performance and efficiency by grouping storage media into separate tiers based on their performance characteristics. It enables performance optimization, efficient resource utilization, automated data placement, Quality of Service settings, scalability, and simplified management of storage resources within a storage pool.

Define and configure storage tiers within a storage pool.

In QuantaStor, the "Create Storage Tier" feature allows you to define groups of Storage Pools with similar properties. For example, within a storage grid you may have several all-flash pools that are ideal for databases and VMs and several lower cost storage pools which are ideal for backup and archive workloads.

With Storage Provisioning Tiers those pools can be grouped together into a "Gold" provisioning tier for the all-flash storage and a "Silver" provisioning tier for the lower cost archive storage. Once created all CLI/API commands which require a Storage Pool ID can be called using the ID of a Storage Provisioning Tier rather than a specific Storage Pool.

The system will automatically choose the pool with the most free-space and will also take into account over-provisioning so that a fairly even balance can be achieved across pools.

The purpose of this feature is to make it easier for automated systems to provision storage from a QuantaStor storage grid without having to do complex analysis of the various pools in order to get a good match to a given workload's use case. Further, tiers can also contain location information so that the storage can be provisioned from systems local to the workload. For example, say your organization has a east-campus and a west-campus and a given workload requires high IOPS for a database. It could provision from a tier named "east-campus-gold-tier" and QuantaStor will automatically determine which pool is the ideal one to provision from given the group of pools within the Storage Provisioning Tier "east-campus-gold-tier". Similarly a user on west-campus needing archive storage could provision from "west-campus-silver-tier" to get low cost storage allocated for backups.
