Once upon a time (earlier versions of BPCS) SSA GT had what was known as a Sizing Questionairre. Filling it out can be a pain.

Into it you put statistics like the size of your business
(how many transactions a day of various kinds)
(how many years you need to store history of transactions)
(how many invoices, average lines on invoices)
(how many customers ... various metrics)
what BPCS applications will you be running
how many different languages needed - do that on partitions by country or what - because that can mean multiple copies of OS/400 and BPCS software
how many different environments needed, because there may be tailoring needed differently for different divisions of the company
average number of concurrent sessions per user
how fast you want your performance
(subsecond response)
what IBM features you need to be using
what other stuff you want on your system OTHER than or in addition to BPCS

Then from the results of the Questionnairre, SSA and GT and any number of intermediate consultants could tell you how fast a processor you needed on what model 400.

Good afternoon:

 I am attempting to obtain information regarding iSeries system sizing for
BPCS release 8.X

 IBM suggested that we have 65 arms [DASD] and that a 825 3 way processor
would be enough power to operate over 500 users.

any thoughts
