Hi Al! Did it take into account Sync Rem Copy (PPRC and the like)? I don't even remember if PPRC had been released back then.

If you are a member of CMG or are willing to register on their website you can find my 1998 paper "DOES YOUR INSTALLATION HAVE HALF-SECOND I/O RESPONSE TIME? (A Closer Examination of Disconnect Time)". I believe that paper first explored how to use the SMF 42-6 data to better understand response time for cache hits and cache misses. Hard to believe that was 15 years ago that I did that work.
