I need some arguments to sell Iseries instead of windows to serve Lotus
Domino

A customer has a proposal to have six (6) windows 2003 servers, running
Domino but I am proposing a single System I running all services in one
box.

Needing some extra-arguments to deploy such a sollution

Thanks in advance.

Plenty of flag waving from IBM here:

including details of record-breaking Domino performance:

and why to run Domino on AS400:

Thanks a lot.

I have added that I series are inmune to virus. At least known virus, so
there is no need to spend money and cpu resources in antivirus software to
check all system files except perhaps email files.

A windows server spends at least 30 percent of resources scanning what it
serves Antivirus software is mandatory in windows

Not entirely true. While the iSeries is pretty invulnerable to viruses,
the Domino implementation is just another mail server, and the client
will open mails and attachments on Windows boxes. So any viruses will
just sit inside the mail waiting to be opened by the client, on windows.
Hence, you will need to run an mail scanner on the iSeries, or on the
client; preferably both (different manufacturer would be nice, e.g. my
client runs Sophos on the PC's but ScanMail (TrendMicro) on the iSeries).

And if you want a case for iSeries vs. Windows: Some years back (you may
be able to Google on it) IBM AMRO replaced well over 100 Windows boxes
by 5 iSeries boxes for world-wide Domino. iSeries is supposed to be an
undesired platform within ABN AMRO, but they have plenty of them.

If they really are opposed to iSeries, try and sell'm Linux. Windows is
your worst option. Cost of Ownership for iSeries is about 30% of that of
Windows, and about 50% of that of Linux (IIRC from a white paper by IDC).

A virus scanner on I series by now should be only limited to IFS files
shares and email. It has no need to check all os system files or standard
5250 aplication or database objects ........ as long as I know those virus
target Windows not the System I itself , I mean the Server is inmune..

Be aware that if they have 6 server they possibly have a domino cluster
made by 6 servers, this choice is usually based on the need of High
Availability, non only by a performance view.
This way you should think to have at least 2 iSeries boxes to benefit
domino clustering.
An advantage of iSeries, is that you can configure multiple domino
servers inside the same iSeries OS400 partition, while on windows you
are limited to 1 domino for each installed os, but you can still
virtualize multiple windows inside the same xSeries box. So you can
retroduce the same configuration of 6 domino servers in a single box or
2 boxes only to benefit the cluster HA.
You do not said anything about how many mail/calendar users and domino
applications, if any, and how much havy they are. Usually domino
applications are CPU intensive and RAM consuming, the iSeries ipotesi
should be thought in the same terms of CPU clock and RAM size. E.g. if a
domino application uses a 3.0GHz CPU (very common for intel), more or
less you should have a two-way iSeries to have comparable performances.
