Hallo,
ich kann mich bzgl. den Preisen, dem Service und der Leistung
der neuen I5 meinem Vorredner keinesfalls anschliessen.

Hier ein paar Informationen aus einem Announcement:

The most obvious future technology that is coming as part of the on-demand initiative is a new hypervisor for the "Squadron" Power5 and future Power-based servers that will be able to support OS/400, AIX, and Linux concurrently on the same machine, within much more flexible and much more granular logical partitions. This means OS/400 partitions running DB2/400 will be able to sit side-by-side with AIX partitions, running popular non-IBM Unix databases from Oracle and Sybase, as well IBM's own DB2 and Informix databases. What's equally important is that a whole slew of specialized Unix applications for data warehousing and technical computing will be, for the first time, available on the same box for OS/400 shops. Those AIX and OS/400 partitions will share virtualized I/O, and will communicate through the memory buses in the iSeries box, using virtualized LAN links. This is going to be a great thing for lots of customers who have a mix of OS/400 and Unix applications. There will be a place for Linux applications on this Power5 iSeries, too, mostly supporting Web infrastructure workloads, like Web servers, firewalls, load balancers, and such. If real Linux applications take off in the market, the iSeries will be able to run them on the same machine. In short, the Power5 iSeries will give customers a single box that lets them be relatively agnostic about the operating systems they put on that box.
