BPCS Sizing Issues

Tom,

It sounds like your situation is very similar to what my company has 
experienced. We were not an AS/400 shop prior to purchasing BPCS.  In the fall 
of 1996, we completed the SSA sizing process.  Shortly thereafter we purchased 
a 510-2143, 384MB Memory, 16GB Disk (12GB Usable with RAID5) specifically to 
run BPCS. 

During our implementation process with a limited number of users on the system 
(6.0.02 plf cum3 Mixed Mode), disk space filled up to almost 90% and 
performance was sluggish in certain programs (Especially billing and some of 
the manufacturing programs).  At that point in the fall of 1997, we went 
though the entire sizing process a second time with SSA.  We noticed that the 
format of the sizing questionnaire had changed between sizing #1 and sizing 
#2.  SSA came back with new reports stating we could not go live with our 100 
users on the AS/400 that we originally bought, and would need to buy a 
620-2181 or S20-2177.  This was quite a financial shock to our relatively 
small company (130 employees) since we weren't even live on the first system 
yet.  Consequently, our implementation was placed on hold until the sizing 
issues could be resolved.  We've already spent a million dollars on the 
project, and now we are looking at close to another million to move forward.

We have spent months trying to get SSA and the other involved parties together 
to discuss a a resolution to our issues.  Although we have now had some 
meetings, very little concrete progress has been made to date.  

You mentioned in your email that your company will "probably move up".  I am 
curious to know if your company or any other company out there has had a 
similar mis-sizing experience like ours.  If so, how were you able to resolve 
it, or are you still in limbo like us?

I would have to agree.  We are running 6.0.2plf on a model 510-2143 512k mem
with 150 users and performance is bad especially in the  Billing and Shop
Floor Control areas...  We will probably move up...
