   A company runs a PowerSizer analysis for a new virtual desktop infrastructure (VDI) environment. The output recommends a PowerStore 500T with 20 TB effective capacity and 15,000 IOPS. The VDI team estimates that the environment will need 18 TB usable capacity and 12,000 IOPS at peak. What should the storage architect do next?

   • ASelect a smaller model because the capacity requirement is only 18 TB, which is below the 20 TB of the 500T.
   • BAccept the recommendation because the PowerStore 500T meets both capacity and performance requirements.
   • CRe-run the sizing with only the peak IOPS to ensure the model can handle bursts.
   • DRequest a larger model because the 20 TB effective capacity is less than the 18 TB usable capacity after RAID overhead.

   A storage architect is sizing a PowerStore for a mixed workload of database and file services. The initial PowerSizer run recommends a PowerStore 1200T, but the architect notices that the database workload has a high write ratio that may cause performance issues. What is the best practice for refining the sizing?

   • AManually increase the capacity requirement to compensate for the write-heavy workload.
   • BAccept the recommendation because PowerSizer automatically accounts for write ratio in its default settings.
   • CSelect a higher model without re-running the sizing to ensure sufficient performance.
   • DAdjust the workload profile in PowerSizer to reflect the actual write ratio and re-run the sizing.

   A company is evaluating PowerStore for a new virtualized environment. They have a rough idea of the workload but want to use PowerSizer to refine the model selection. What is the correct way to use PowerSizer in this situation?

   • AEnter the estimated workload and capacity, then review the recommended model and adjust inputs if needed.
   • BSkip PowerSizer and choose the largest model to avoid any performance issues.
   • CUse PowerSizer only after the environment is fully deployed to validate the configuration.
   • DRun PowerSizer once with the most optimistic numbers to get the smallest model.

   A university is sizing a PowerStore for a research storage environment. The researchers will store large files (up to 1 TB) and access them sequentially. The IT team knows the total capacity needed but is unsure about the IOPS requirement. What should they do to obtain a valid PowerSizer recommendation?

   • ASkip the IOPS input and rely on the capacity-based recommendation.
   • BUse the maximum IOPS value allowed in PowerSizer to ensure performance.
   • CProvide an estimated IOPS based on the expected number of concurrent users and typical access patterns.
   • DEnter only the capacity and let PowerSizer assume a default IOPS value.
