Ron, >From the discussion so far, it seems that I have little to really worry about. So at this point, I'm just curious.
I do not know what are the potential performance limiting factors are for the following: 1. The FICON cable/protocol 2. The IBM's processor channel card 3. The IBM's storage channel cards 4. Any switches along the path Thanks, Don -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Ron Hawkins Sent: Monday, January 25, 2010 12:19 PM To: IBM-MAIN@bama.ua.edu Subject: Re: PAGE datasets -- few large or more small Don, If by multiprocessing you mean the number of processors available and executing concurrently, that largely depends on the architecture of the storage vendors Channel Cards.
