We run SAP on Windoze with about 200 users online at once. It works reasonably
well, and I can't recall when we last re-booted the SAP servers. I know they
are shut down over daylight saving changes for some reason, but other than that
perhaps the odd tine when applying MS updates.
However SAP is a beast and in order to get it to perform it needs to have
plenty of devices to spread the i/o over. I do see i/o bottle necks from time
to time, and when I persuaded them to move the main database files to a
dedicated tray of disks in the SAN things improved markedley.
The BIGGEST problem with Windows is that managers (mine included) don't
understand that you need to design the server platform. They think you can just
sling in any config and it will work. For big systems such as SAP You MUST
design the storage subsystem for I/O throughput NOT for capacity......

My 2 cents....Two previous employers dropped the mainframe for SAP one on HP
UNIX the other laughably on WINDOZE servers.
The HP conversion was budgeted at $10 mil .. a few years and $50 mil later
the company went bankrupt. Company 2 managed a sucessful conversion but now
they spend all of their time adding hardware and rebooting WINDOZE. There has
been no savings or increase in productivity.

When done right, it can be a good thing. But yes, it does take a fair number
of people and a good deal of planning. The System z deployment is saving them
(the NYC company) a boatload of money, though.
Their SAP implementation on z is much faster than the one they came from
(which I think was Solaris, or maybe AIX).

Hello Rich,
I am always amazed at the cost of SAP and salaries commanded by SAP
