    LUN Utilization in EMC arrays


      I was reviewing performance parameters in one of our EMC VNX storage box. While checking the LUN utilization parameter found that all top 5 LUNs has a cap till 50% utilization. On curiosity i extracted and review EMC's own performance (NAR/NAZ) files and found that actually those LUNs are 100% busy most of the times. Not able to understand why STM is showing like this. Please find below screenshot for reference. Would be grateful if anyone can help me understand why all highly utilized LUNs are showing like this in STM. FYI, we have STM 5.7.1 installed.
