I'm not talking about the operating system, but the middleware and applications. DB2 UDB for Linux is the same price based on the number of engines. I can support more users on a 390 engine then an Intel engine. Hence I need more copies under Intel. Same for Websphere and then we get down to the applications. Given the rule of thumb of 100 Intel servers can be consolidated to a single 390 server... 100 copies of DB2 costs a lot more than 1 copy 100 copies of Websphere costs a lot more than 1 copy 100 copies of NT costs more than 1 copy of VM I thought I saw that DB2 UDB was $20K per server/engine. So, just on a software side, DB2 under Linux/390 being able to replace 3 copies of DB2 UDB on Intel, would basically reach a break even point. z/VM 4.x $45,000 DB2 UDB for Linux $20,000 Total: $65,000 DB2 UDB for Intel: $20,000 per copy 3 copies: $60,000 Of course, if anyone has real numbers, I'm all ears...
