IBM has positioned themselves very well by making sure that linux runs on both the pSeries hardware AND the zSeries in addition to the xSeries (Intel line). There is an offical support policy for linux on Power.
I know Sun just added that to the Sparc line but I'm not sure where HP stands. Is Linu

As to the specifics of the T1 and P5, I think I'll do some digging. In the end you're comparing more than just the machine. The OS comes into play as well. I think a fairer benchmark would be Linux on Power and Linux on Sparc running a non-vendor specific package. For instance in the DB2

IBM's Power4 came out years ago as "dual core" on the same chip. Little fan fare. The cores share L3 cache (now they're all doing that too), but little else, and you really got 2X+ performance from their multi-core implementation.
I believe Sun implemented (questionable word here) dual core in enough of a different way so that you really get less than 2X performance over a comparable speed single core chip. I

I'd like more info about the "best of the breed" part. If you click on the Performance heading on the above page you can find a PDF to read about the tests, but as in a lot of these cases it's pretty cryptic. I'd love to see a comparison between the newest Opterons and Power 5.
It's nice to have a solid competitor to x86 though, especially seems how SPARC seems to be losing momentum with Sun using AMD in it's new X series.

When your datacenter says they won't let you buy any space because of cooling issues, Opterons start looking a little better.

Caveat Emptor: I've never used VMWare servers, so I don't know how good or bad they are. I've only used zones in the Solaris 10 course I did, so don't have a lot of real-world experience of them so far. Both solutions will
