The only thing I can think of that DFSORT and a DASD device have 'in common' is Cache Fast Write. Maybe you had it on on the DS8100 and not on the DS8800. Although I cannot figure out immediately what effect this has on memory, except that the CFW I/O is probably faster.

Immediately after we configured and then moved our page datasets to a DS8800, a number of DFSORT jobs started consuming all available (and sometimes not so available) memory. We noticed in the sort itself that while we originally used 900M memory objects used as main storage and none for work storage, it reversed after we started using the DS8800. Nothing used in main storage and 6000M memory objects in work storage. No parameters where changed, no maintenance was applied, no one snuck in and changed JCL, programs, utilities. Nothing happened except we put our page datasets on the DS8800. We didn't move anything else. Any ideas what would cause that? Thanks, Anne R.
