   What is a best practice when using PowerSizer to size a PowerStore solution?

   • ARun the sizing once with the most aggressive performance estimates to ensure headroom
   • BSkip validation and rely solely on the tool's default recommendations
   • CUse the tool iteratively, refining inputs based on initial results and validation
   • DUse the same inputs for every customer to save time

   A company has run PowerSizer and received a configuration report recommending a PowerStore 900T with 40 TB effective capacity and 30,000 IOPS. The report also includes a performance summary showing the workload's read/write ratio and latency estimates. What is the most important use of this performance summary?

   • ATo identify the firmware version needed for the PowerStore
   • BTo calculate the total cost of ownership for the solution
   • CTo verify that the recommended model can meet the application's performance requirements
   • DTo determine the physical rack space required for the PowerStore

   A hospital is sizing a PowerStore for a new electronic health record (EHR) system. The EHR vendor specifies a steady-state workload of 8,000 IOPS with 70% reads and an average block size of 8 KB. The hospital also expects to store 12 TB of patient data initially, growing 20% per year for five years. The storage administrator wants to use PowerSizer to determine the appropriate PowerStore model. Which set of inputs should the administrator provide to PowerSizer to obtain an accurate sizing recommendation?

   • ATotal capacity only, because PowerSizer automatically estimates performance from capacity
   • BWorkload profile (IOPS, read/write ratio, block size), initial capacity, and annual growth rate
   • CNumber of servers, network bandwidth, and RAID protection level
   • DPeak IOPS, read/write ratio, and number of LUNs to be created

   A company is migrating from an existing storage array to PowerStore. They have performance data from the current array, including IOPS and latency, but the data was collected during a period of low utilization. What is the best practice for using this data in PowerSizer?

   • AUse the lowest observed IOPS to ensure a cost-effective solution.
   • BUse the data as a baseline and adjust for expected peak utilization.
   • CEnter the data as-is because PowerSizer will automatically scale it.
   • DIgnore the historical data and use only the vendor's recommended values.
