Nathan,

For their needs, they should have gone with the i5 or better, MVS, to scale
both ways all on one box, not 3,000; how dumb but that's PC thinking.

They said they were running about 3,000 servers. At first they tried scaling
vertically, using 16-way servers, but when that didn't work, they went with
horizontal scaling. The database server was a constraint, so they partitioned
the database across 60 DB servers.

The biggest constraint now appears to be the time it takes to maintain
applications across thousands of servers.

What I more want to know, and am guessing nobody here can really
answer, is how much work (hardware, software, etc) is required to do >this
with M$ vs. IBM?

Good question. The i5 would scale better vertically, up to 64-way servers, but
at some point you'd need an architecture that scaled horizontally.

Interesting the MySpace.com guy said that he can't imagine doing
this on any other platform than Microsoft ...

He also said they pulled their hair out every night.
