Take a good look at which ox is being gored.

UNIX server counts are down, and revenues are down, because TCO for
UNIX has been dropping radically.  UNIX servers such as Sun ES/400s
with 4 processors running at 100 Mips are being replaced with
partitioned servers such as StarFires, Regattas, and Superdomes with as
much as 128 processor cores, each running at the equivalent of 40 times
faster.  Put another way, one new UNIX server is doing the work of
10240 SparcServer processors.  More realistically, You can do the work
of about 1000 of the old UNIX servers with one new server.

Or, perhaps, just rebalance their systems according to their needs.

That makes sense.  A Linux server, running on a 1 Ghz server with a
pair of RAID 200 gig hard drives can easily handle email for a few
hundred users, maybe even a few thousand (if you limit them to 50 meg
of storage locally and they use POP e-mail clients).

Linux does a better job with applications that have been designed to be
clustered.  Traditional UNIX does a better job with larger applications
and threaded applications such as DB2, Oracle, Sybase, SAP, or Seibel.

More often, the best solution is to balance the two technologies.
Cluster what you can, and SMP what you can't.  And than brings us to
the good stuff.

These new partitioned UNIX servers can do the work of hundreds of older
UNIX servers, but they can do the work of thousands of NT 4.0 servers.
So many times, applications had to be broken into lots of little pieces
to keep the servers from ending up in DLL Hell.  UNIX servers can not
only provide much of that functionality, but there is less need to
break the pieces up.  And when you do need to break them up, when Linux
or Unix flavors are available, it's much easier to put them in a
partition.  Because you have the ability to farm jobs out to each of
the processors, you have better redundancy.  This means that you don't
need twice as many servers as you are actually using.

What's really fun is to look at the growth in Unit volumes vs growth in
revenue.  It's really interesting, and shows how dramatically the TCO
is dropping.

Conversely, look at the Microsoft Server revenues and the server
"growth" rates.  It pretty dramatically shows that TCO for Windows is
going up.

But Red Hat Revenues are up 40 percent, Novell revenues are up 80%, and
yet server and services revenue is only up 15%.  Kind of tells me that
Linux is giving me a lot of bang for the buck.
