SAP Sizing

Sizing is important when it comes to SAP. SAP is very resource hungary. It takes up a lot of hard disk space and a lot of memory.

We therefore would want to make sure we have enough hard disk, memory etc for the business otherwise we are going to get a lot of complaints.

First off, we need to ensure the hardware we are planning to buy is supported by SAP. This information can easily be found on the SAP web site.

We next ask the suppliers of the hardware (for example IBM) to size the solution.

They may provide consultancy and most likely ask us to fill in a questionnaire. The following is a link to a questionnaire from IBM. It is good to have a look at this as it provides details as to what information is required to size SAP.

The hardware suppliers may also ask you to fill in the SAP Quick Sizer. Once filled, this will provide a number on SAPs which is the number of standard dialog requests per hour (good idea to increase this a little). The hardware suppliers would then be able to make a recommendation.

Some additional info
To find out information about the SAP product, we can use the Product Availability Matrix (PAM) on the SAP website. http://service.sap.com/pam - this requires a SAP logon. Once you are logged in, search/click for the SAP product, e.g. SAP Netweaver 7.0. From the “General” tab, click on “Installation/Upgrade guide” – here you will be able to find documentation on planning/installing/upgrading etc.
