I realize that this has probably been asked before, but google didn't
give me an answer. Before I asked my question let me state that I
know that windows server 2003 and longhorn won't run on an IBM
mainframe. There is the endian issue and the ascii vs ebcidic
issues. Is there a medium to large IBM box that can run a couple
hundred of virtual windows 2003 servers? And said box can scale up to
approximately 1000+ virtual windows servers? Given that all current
servers are dell and hp servers with 2 intel core 2 duo processors and
a total of 150TB of storage?

I am doing research for the possible replacement of 200+ windows
server in our datacenter. We need to add servers, but there is
literally no more power. My thinking is if IBM can get windows
servers to run on their something like their mainframes it would save
electricity and space. Everyone would win.

recent cross-over from another thread:
http://www.garlic.com/~lynn/2007l.html#63 Is Parallel Programming Just Too Hard?

mentioning that blades are also being sold into commercial market,
frequently in combination with virtualization, for server consolidation

and another mention here ... in slightly older thread/post:

the previously mentioned scaleup activity was in large part about
physical packaging and issues like power and cooling

but the server consolidation is now frequently blades/grid technology
in combination with virtualization .... curtesy of science center

morphed into cp67 (precursor to vm370) ... misc past posts mentioning
science center

besides virtualization and virtual machines being invented at the
science center ... compare&swap instruction for
multi-thread/multi-processor was also invented at the science center

and also GML (later morphed into sgml, html, xml, etc)

and most of the internal network

which was also seen outside in deployments like bitnet and
