• Question 75:

  A customer plans to aggregate a number of CLARiiONs to a Symmetrix VMAX with FAST VP. Which data collection requirements are recommended for a Tier Advisor analysis?

  A. Minimum 5 hour NAR and trace data collection with both NAR and trace data collected at 2 minute intervals.

  B. Trace data for 30 minutes each hour of NAR capture.Minimum 8 hour NAR data collection at 10 minute intervals for coarse data analysis.

  C. Trace data at 1 minute intervals for detailed peak data capture.Maximum 24 hour NAR and trace capture at default 10 minute intervals to enable peak analysis on a daily basis.
