Sizing for PowerStore Solutions:

Accurate sizing for PowerStore solutions requires specific workload parameters to ensure that the storage system meets performance and capacity requirements.

Required Parameters:

IOPS (Input/Output Operations Per Second): A key performance metric indicating the number of read/write operations the system must handle. Essential for determining the required performance capability.

Effective Capacity: The usable storage capacity after considering data reduction technologies like compression and deduplication. Critical for ensuring the system can accommodate the data volume.

Other Parameters:

Response Time: While important for performance, it is not typically required to proceed with sizing.

Data Reduction Ratio: Influences effective capacity but is not a direct input for initial sizing.

Dell Midrange Storage Reference:

Dell PowerStore documentation provides detailed guidelines on the parameters needed for accurate sizing.

Community forums and support resources from Dell Technologies offer additional insights and best practices.

Dell recommends scheduling FAST VP (Fully Automated Storage Tiering for Virtual Pools) relocations before backups or nightly batch processing to ensure optimal performance. This scheduling helps to avoid conflicts and performance degradation that can occur if relocation tasks compete for resources during critical data operations such as backups. Pre-scheduling these relocations ensures that the storage system is balanced and ready for intensive operations without impacting performance.

For a PowerStore 5200T system with a mixed SSD and SCM (Storage Class Memory) drive combination, the following statements are correct:

Expansion Enclosures are supported: PowerStore 5200T supports expansion enclosures, allowing for the addition of more drives to increase storage capacity and performance. This flexibility is crucial for scaling the storage system to meet growing data requirements.

SCM drives do not add to usable capacity: SCM drives in the PowerStore 5200T are primarily used for caching purposes rather than for adding to the system's usable capacity. These drives improve performance by accelerating data access times but do not contribute directly to the overall storage capacity.
