SAP on AS/400Hello Luis,
a) According to recent statistics that IBM uses in their sales
materials, there are over 1200 SAP installations on AS/400 and/or iSeries.
Of those, there are over 100 that are live on 4.6 releases and over 170 that
have 4.6 releases installed. This grows every day.
b) Information on reference clients should be obtained from an SAP
Application Engineer or an IBM sales representative. However, some names
that have been published include:
SUTTER Home Wines (USA)
STARWOOD Lodges (USA)
KERR Drugs (USA)
LINDT & SPRÜNGLI (Switzerld.)
TARONGA ZOO (Australia)
DAIRY FARMERS (Australia)
PROGRESSIVE (New Zealand)
NORTHERN FOODS (United Kingdom)
GARDNER DENVER (USA)
BALL HORTICULTURAL (United States)
SONY (Australia, India)
BAYER (Canada, Spain)
AGFA (Germany, Canada)
DOMO Group (Belgium)
INTEREUROPA BANK (Hungary)
OKD (Czech Republic)
As you can see, the AS/400 is well represented all over the world.
c) The maximum size of a productive R/3 installation is hard to find. I
have worked with customers (no names mentioned here) that have a database
size approaching 1TB. DB performance is not an issue here. I have worked
with customers recently who have had average direct read times of .1ms,
average sequential read times of .2ms and average change/commit times of
1-2ms. Oracle and SQL server people only dream of numbers like these.
Current platform statistics will allow me to attach over 18TB of disk and
128 GB of memory. This is growing shortly to over 36TB of disk and 256GB of
memory. All of the iSeries detractors say that the platform just isn't
scalable enough. My question is: What does the platform have to do to be
d) Technically unique. The native database is EBCDIC and for years this is
how the R/3 product was implemented on the server. The other platforms are
ascii. However, SAP and IBM have come out with a version for the iSeries
that is an ASCII solution prepared well to handle multiple code pages and
makes the path straighter for conversion to Unicode in the future. Other
technically unique features include: iSeries doesn't have to participate in
the MCOD (Multiple Components One Database) initiative because it has
handled this situation for years. On the iSeries, I don't have to find
valid combinations of OS and database. I don't have to allocate space for
tables and monitor the database for full conditions or too many extents. I
don't allocate memory for database buffers, set page cleaner numbers, etc.
I don't have to go through major conversions of applications when hardware
technology changes for the platform. I can take advantage of large amounts
of main storage just by adding it to the server (and it actually does help).
One consideration is cost. Depending on the implementation, iSeries
hardware can cost 10 to 15% more initially. This is usually offset early on
in the implementation because of higher availability which helps the project
team to be more effective. Over the longer term the total cost of ownership
can be significantly different depending on the solution chosen. For
smaller companies, ongoing support costs over 5 years can be nearly twice as
high for wintel type solutions and 60% higher for Unix solutions. For
larger companies the numbers go down to about 70% higher (wintel) and 58%
higher (Unix). This is according to an IDC study.
I hope this helps. If you have any further questions, you can get in touch
with me using the information in my signature.

My name is Luis Carranza. I work for PricewaterhouseCooperse. We have
a potential client evaluating SAP on the IBM AS/400 platform and I
am looking for any information specific to the platform.
a) number of installed SAP systems/ total SAP installs
b) reference clients running SAP on AS/400
c) maximum size of a Productive SAP on AS/400 platform
d) anything technically unique about AS/400 SAP
Basically anything that would make the platform more or less
desirable for an SAP implementation.
I will appreciate if you could provide me with that information or
point me to the place(s) where I can find that information.
