Understanding DRR (Data Reduction Ratio):
The Data Reduction Ratio (DRR) is a measure used in storage solutions to determine the efficiency of data reduction technologies such as deduplication and compression.
In NVMe-based systems like PowerStore, achieving an optimal DRR is crucial for balancing capacity and performance.
Sizing PowerStore Solutions:
When sizing a PowerStore solution, it's essential to align the provided capacity and performance (IOPS) with the customer's requirements.
If the recommended solution vastly exceeds the requested capacity (10 times more in this case), it indicates an overly conservative DRR assumption.
Recommended Action:
The architect should adjust the DRR to reflect a more accurate estimate that aligns with the customer's actual data reduction potential.
This adjustment ensures that the solution is cost-effective and meets the performance criteria without excessive over-provisioning.
