So Moore's law works against you on the z as well.... I'm not talking about existing MF customers.

If you have two machines, each doing half the work, the costs get doubled? I think you're a bit confused. And who gives a fuck about your one customer? I can show you fucking hundreds who made the exact same mistake with Intel tin.

The more boxes you have to consolidate, the better the picture is for Linux on z. > And there's another factor...

Suppose you can, well, then you should. But how about if you could replace 250 rack servers with a single mainframe? I work in plenty of IDS sites where they don't have a lot of database servers, but they do have a gazillion app servers and web servers and other servers ... all running Linux. Then the picture looks a bit different. > The point is otc... you have a lot of factors to have to consider as > part of your thought exercise. The difference in the cost of the > physical plant can mean a *lot* of money. Yeah. The cost of running the leccy and aircon for a single server or for 250 servers. It *can* mean a lot of money. > Of course there is one other thing... switch your database from DB2 on > the mainframe to GreenPlum since IDS doesn't come in a MP flavor > anymore....
