Symmetrix performance values or standard matrix are not as straigh forward as CX. You have various factors involved due to the way the symmetrix handles the IO although the components are similar to CX.  Although if you search for performance documents, you wont be able to find any numbers as they vary according to configuration, host environment, connectivty and several other factors in symmetrix.  As dynamox mentioned, any thing above 50% can be considered as the trouble making one in the future. What tool are you using for Symmetrix performance monitoring.  There are few things that I can refer for initial checking.  Cache Hit Ratio should be 90% for ideal cases and FTT of DAs should not be less than 1000 for longer periods. All FA utilization should be less than 70% and balanced Write pending should not be above 50% Device write pendings should not exceed threshold limit verify the disk utilization and see if there are any disks that are much busier than the other.  you have lot of disks, DA, FA components involved so it will not easy determine the values right away.  Probably dynamox or RRR or Marc or Stefano can or add or change. These are not accurate, just some baselines.  give me a call if you required..
 Hi All  Some one can provide some aggregate values on symmetrix performance to verify the utilization,Response Time and Queue Depth. I know the exact values on Clarrion as we normally configure on Navi Analyzer with Utilization - 70 % , Response Time 20 MS and Queue Depth as 10.  Some one can provide the values smillarly on Symmetrix.  Require Thresh hold values on Cache Hit Ratio smillar to Hight water marks and low water marks. Is there any performance document on Symmetrix smillar to this sort of document : h5773-clariion-best-practices-performance-availability-wp.pdf  What is the Cache Hit Ratio valuesIs there any parameters Like Low Water mark and High Watermarks on Symmetrix If the Cache Hit Ration is 100 & is that good as per the symmetrix performance Analyzer report. Is there any standard performance file where normally EMC follows and send to the customer on symmetrix. can you share one file as a reference to me. I have my clariion stuff i.e PDF where normally sends by EMC to customer.  RegardsVithal
Aggregate values on symmetrix performance?
