Windows runs on a Xeon co-processor
Not quite, the IXS/IXA are IBM xSeries ("x" means Intel) servers that are integrated with the POWER5 iSeries. IXS is an internal co-processor, IXA uses a separate Intel box.
Morky said:From IBM's eServer 520 product page:
Delivering a breakthrough in infrastructure simplification, the 520 is capable of running i5/OS, Microsoft Windows, Linux, and AIX® 5L applications simultaneously on a single server and can integrate IBM..
The 520 is a Power5-based system. It appears to be some kind of very low level emulation capable of running the x86 instruction set at nearly full speed.

Integrated xSeries Server for iSeries
The Integrated xSeries Server features a 1.6 GHz Intel Xeon processor with 512 KB L2 cache, a 400 MHz front side bus (FSB), and an on-board 10/100 Mbps Ethernet controller and 4 USB ports.
The Integrated xSeries Adapter is a PCI adapter that connects xSeries servers to the iSeries HSL bus, and provides the server vitual storage and Ethernet. The Integrated xSeries Adapter is supported with a range of xSeries servers, including the x235, x255, x360, and x440.
