   A financial services firm is sizing a PowerStore for a transaction processing system. The system requires low latency and high IOPS. The storage architect has the following data: 10,000 IOPS, 90% writes, 8 KB block size, and 5 TB of active data with 10% annual growth. What is the most critical input to ensure the PowerSizer recommendation meets the performance requirement?

   • AThe annual growth rate of 10%
   • BThe write-heavy workload profile (90% writes)
   • CThe block size of 8 KB
   • DThe total capacity of 5 TB

   A storage administrator runs PowerSizer for a new PowerStore deployment. The output shows a recommended model with 25 TB effective capacity and 20,000 IOPS. The administrator also sees a note that the configuration includes 10% spare capacity. What does this note indicate?

   • AThe administrator must manually add 10% more capacity to the recommendation.
   • BThe model is 10% larger than necessary, so a smaller model could be selected.
   • CThe effective capacity already includes a 10% buffer for future growth.
   • DThe IOPS rating is reduced by 10% to account for overhead.

   A small business is planning to deploy PowerStore for their ERP system. They have limited IT staff and want to ensure the selected model can handle their expected workload without over-provisioning. What is the primary role of PowerSizer in this scenario?

   • ATo automate the installation and configuration of the PowerStore system
   • BTo monitor the performance of the PowerStore system after deployment
   • CTo generate a bill of materials for the physical installation
   • DTo recommend the appropriate PowerStore model based on workload and capacity inputs

   A storage architect is reviewing a PowerSizer output for a mixed workload. The report recommends a PowerStore 700T with 30 TB effective capacity and 25,000 IOPS. However, the architect notices that the workload includes a large amount of sequential reads, which are not well represented by the IOPS metric. What should the architect do to ensure the recommendation is valid?

   • AIncrease the capacity requirement to compensate for the sequential reads.
   • BAccept the recommendation because IOPS is the only metric that matters for sizing.
   • CRe-run PowerSizer with the sequential read pattern specified in the workload profile.
   • DSelect a larger model because sequential reads always require more resources.
