Our current 2tb, 5k tablespaces , 45k getpage/second DB2 zOS application will be replaced by sap in the next 2 years... <SNIP> Based on my experience of converting from MCP[1] to See-Bull (or Sieble as you prefer), a VSAM master file having records of 4K (with areas multiply defined) turned into a 1MB record. Now, the WHOLE MCP install (all programs, data, page, spool, mirror-ed DASD, etc.) all fit neatly into 3 TB. Moving ONE, count-em, ONE application required a 5TB RAID unit, various and sundry servers, PLUS 4 full blown, "got it all" REGATTAs (each was physically larger than the z/800 1b0). Each REGATTA produced MORE BTUs than the z/800 (to the point that if you were cold in the computer room you could walk behind one of them to actually get warm!). YMMV. But I was absolutely dumbfounded at the amount of money thrown at moving off a mainframe based system. And the end result was, the CICS based application that was being replaced had SUBSECOND response while the See-Bull system had, well, 5-15 second response. So let me put this in perspective: a customer calls to order an item (whatever it might be). The call handler will need to go through 7-11 screens (CICS) for a total time of 5-6 minutes to handle the call. The See-Bull system required 5 screens (browser based) and took 11 minutes. Again YMMV. And this was sent to Carrico for posting to ReBoot Hill (why? Because it was, in my estimation, a US$100M fiasco that resulted in the See-Bull system being abandoned when they realized that the computer room would have to be expanded for the third time to handle all the hardware...) [1] Prior post -- MCP is my name for z/OS. It is The Master Control Program vis-a-vis IBM revenue for SCPs on z/Architecture, right?
