SolutionMy typical setup for SAP is having all R/3,BW and TPM on different servers:
We started like this.
SAP R/3 server ( Production Server) : N4000 6 cpu 6GB RAM which we later upgraded.
SAP B/W (Business Warehouse):N4000 4 cpu 6GB RAM.
Application Servers : This is combination of L2000 and L1000 with 2-4GB RAMs.
And for Performance sake we have Installed SAP R/3 CI on different L class server.i.e Our R/3 DB was on Nclass and R/3 CI was on L class.
We had earlier used HP-FC60 then shifted to Netaps F840 filer as a storage for R/3 DB But Later on shifted to CLariion EMC FC4700.
The latest developement is we have successfully configured Suse Linux on intel platform for our SAP R/3 application servers.
Hope this will give you a little idea.
Regards,

Re: SAP hardware configuration
DEV system can be smaller say L-Class.
QAS system can be L-Class but have storage need as big as PRD.
PRD system have to be Superdome class (N-Class may do depending upon load).
One needs a great storage of the class XP128/XP1024 range and a good/faster backup solution.
PRD need to directly connected to storage for better throuhput whereas DEV/QAS can be connected using SAN.
Also need a backup server which can have SAN connect.
SAP has a tool called "Quick Sizer" for Initial Hardware Sizing of your Business Processes.

All the best.

Re: SAP hardware configuration
We have over 2000 users, about 600 printers.
We have a landscape of: DEV, QA, PROD.
Basis Team also has a small Test server.
DEV: N-Class 4 way, 8GB ram, 300 GB disk
QA: RP7410 5 way, 10GB ram 1.5 TB disk
PROD: RP7410 5 Way, 10GB of ram 1.5 TB disk
PROD has 3 N-Class App servers (8 way, 10 GB of ram each)
PROD is 2 node cluster with MC/ServiceGuard.
PROD is also DR'ed to city where QA is (using EMC's SRDF).
An approx cost - 5 way RP7410 will cost a little over $200K Canadian.
Best would be to speak to your local HP Rep - they would gladly do a full sizing/cost for you.

Re: SAP hardware configuration
PRD is on one box.
The other applications may involve another box.
SAP has a sizing spread sheet, Talk to your sales person who will present it. This will involve the Systems admin and what is called the functional person(The person who knows how the business works).
It will ask how big is the present
database (future growth, ours doubles almost every year)
How many users (for performance issues and cost of licenses, ours exploded with users who were not on present home built system to include many clerks)
and as previously posted, A DEV box (development box where configurations, security and reports are generated by programmers) This is needed because alot of reports/configuration is being tweaked and are cross client, meaning it could affect the other instances)
QAS where an almost duplicate of PRD(Production is kept for testing of configuration/security of users)
PRD (production)as fast of harddrives as you can get. We went from SCSI/controllers to Fiber channels and noticed a big improvement.
If you are going to do in house there are alot of start up things you need to know, immediatly send someone for BASIS security trainging. Most ASPs/contractors will charge a premium for this person's job. And Security if very detailed in SAP. I am the Security Basis for our company and I tell users that in SAP after getting a login you have to be given the right to even print. Every aspect of SAP is a BASIS security issue that has to be given to each user.
