SAP ERP 2005 ECC 6.0 with Windows 2000 Application Server

[Former Member]

Hi,

We are currently running SAP 4.6C in iSeries model 570 OS V5R3.

I would like to know after upgrade from 4.6C to ERP 2005 ECC 6.0 if we will gain any performance improvement by adding Windows 2000 Application Servers in our environment. Second Question - how much load will be taking away from the iSeries if adding one application server (Memory and CPU).

Hi Ramon,

please be aware that starting with SAP NetWeaver 2004s and mySAP Business Suite Solutions based on this Windows 2000 is generally not longer supported. The minimum requirement has been raised to Windows Server 2003.

Hi Ramon,

Windows appl server are not the "general performance increase" !!!

It strongly depends on your type of load and the general load of your iSeries.

If the iSeries is exhausted, you can reduce with this the CPU load.

On the other hand the DB-time might be higher because of the network transfer. If the result is faster or slower really depends on the situation, this would need to be analyzed upfront.

In general newer 2-tier hardware will be a faster than a 3-tier landscape.

Hi Volker and Christian,

Do you have any documentation you can share with me about performance on iSeries and Windows 2003 Application Server? Our current environment the iSeries with SAP R3 Release 4.6C we don't see any performance issue our CPU utilization is at 30% and we allocated about 8900 CPW.

We are planning to upgrade our R3 system to ERP 2005 ECC 6.0 I started the sizing and I'm looking for alternative options by not upgrading the iSeries but we know we need to add memory and storage. I just want to know how I can leverage the Windows 2003 Application Server?

Thanks,

Hi Ramon,

what hardware do you use at the moment ?

820, 870, 5xx ?

How any CPUs ?

How much memory ?

You are on 4.6C ASCII right now ?

In your case, I don't see, that Win 2003 servers help in performance, I would guess, that the CPU after the upgrade is about 60% which is still ok - then using 3-tier - especially in R3 environments is mostly not good for the performance because of the DB time increasement.

The memory you will need is pretty the same for the iSeries.
