if you are licensed for ECC and performance manager, you can install Symmetrix Performance Analyzer (SPA) and gather statistics about your frames. Another option is to setup storstpd daemon and collect stats that way. Give it to your TC and he can put it into symmerge and give you nice heat maps. New SPA can generate heat maps as well.
What is the best way to get a snapshot of how the symmetrix is performing? Can I have EMC run a symmerge for us. We have ECC 5.2 but we hardly ever use it. We currently do not have WLA data to work with.  I wish to see what the hot spots are on all our symmetrix's.
