Itschak, You can't look at SSA on a 9980V - all the disk drives are on FC-AL. That's a very different set-up to SSA.
What are the response time break-up and cache hit rates you are getting? If you can't cache hit rates from your RMF, you can turn on LDEV recording in Graphtrack and get the info from there.
