SAP's Quick Sizer


   The Quick Sizer is a Web-based tool designed to make the sizing of SAP Business
   Suite easier and faster.
   It has been developed by SAP in close cooperation with all platform partners and is
   free of cost.
   With the Quick Sizer you can translate business requirements into technical
   requirements.
   Simply fill in the online questionnaire, an up-to-date survey that is based on
   business-oriented figures.
   The results you obtain can help you select an economically balanced system that
   matches your company's business goals.

Characteristics and Scope of the Quick Sizer


Characteristics and Scope of the Quick Sizer
   Initial sizings only
   The Quick Sizer does not contain all SAP applications
   Current releases only
   Online questionnaire
   Availability: 24*7
   Quick Sizer results contain requirements for CPU, memory, disk, and I/O


Out of Scope
   Upgrade, re-sizing: out of scope are post go-live sizings (except delta sizing of a new SAP solution)
   Configuration or landscaping
   Customer coding


Limited Scope
   Sizing platform-type SAP software, e.g.SAP NetWeaver Business Warehouse or SAP NetWeaver Portal
   have questionnaires within the Quick Sizer, but have to be handled carefully.

SAP AG 2009/ 10
Budget Usage of the Quick Sizer – Principles


Users
   Concurrently active users (low, medium, high)
          If you don't know the user distribution, take medium activity users
   Rule of thumb: Feasible for up to 200 active users, unless there is
          Strong background activity
          Heavy reporting
          Seasonal or even daily peaks
   Otherwise perform an additional throughput sizing

Throughput
   You can do a simple throughput sizing using three fields only
          Object
          Sub object
          Residence time
   Basic Sizing for CPU and disk
          Average sizing does not consider peaks
          Background processing neglected
          Disk growth is calculated against the residence time you specified



SAP AG 2009/ 11
Advanced Usage – Principles


Users
   Load pattern (low / medium / high activity users)

Throughput
   Mandatory fields average
      Number of objects
      Number of sub objects
      Residence time
   Mandatory fields peak
      Number of objects
      Number of sub objects
      Processing time
   Optional inputs
      Average & peak
      – % of changes and displays to object (CPU)
      Average only
      – Flag: archiving will be done (no influence on calculation, but check for
        archiving objects)


SAP AG 2009/ 12
Expert Usage – Principles


Users
   Load pattern (low / medium / high activity users)

Throughput
   Multiple averages and peaks
          Create additional input line
          ID-field: Allow for checks of different averages against different peaks

Navigation – Limit User Access

1
                     If you check the flag “Limit user access“, only you
                     as project owner can grant other persons access to
                     the project data:
                      Enter the user-IDs of these persons and choose the
                      “Add user” button (then you see these user-IDs in the
                      drop-down listbox)
                      To delete persons from your access list, set the cursor
                      on the user-ID in the drop-down listbox and choose
                      „Delete user“

                     In your project overview list protected projects are
                     marked

                     If you uncheck the flag, your project can be
                     accessed by everybody who knows the customer
                     number and the project name




SAP AG 2009/ 19
Navigation - Search

1
                  The search is version dependent.
                  The program searches for your search string across the visible and invisible parts of
                  the Quick Sizer. The results are displayed in the navigation tree.
                  All result lines are marked with an information icon.
                  If the string is found in the visible parts, the search string result will be presented bold
                  and enlarged.


                  If the search string is found in the invisible parts, the entire result line will be
                  presented bold, enlarged, and in italics.


                  If a result only partially contains the search string, only the search string is marked
                  bold and enlarged.


                  If you check the flag “Match whole word”, words which only consist of the searched
                  word are displayed. For example, if you enter “HR” without the flag, you also get “…
                  synchronized …” in your search results. If you check the flag “Match whole word”,
                  these kind of results will not be displayed.
                  You can also choose between “Phrase”, “Or” or “And”:
                         If you choose “Phrase”, you only get the results which contain the exact
                         search string. For example, if your search string is “Sales & Service”, you get
                         results such as “Sales & Service”.
                         If you choose “Or”, you get all results which contain one or more words of
                         your search string. For example, if you search for “Sales Service” you get all
                         results which contain either sales or service or both.
                         If you choose “”And”, you only get the results which contain all your search
                         strings. For example, if you search for “Sales Service”, you only get the
                         results which contain both words.

Side Step: Error Handling 1/3


Input errors such as
   Mistyping - e.g. give in letters instead of numbers – will be automatically cleared

There are basically two types of error handling:
   Non-requested
          Upon leaving the questionnaire (indirect save)
          When you save the questionnaire data
   Requested
      Use check function




SAP AG 2009/ 27
Side Step: Error Handling 2/3


You can use the check function to see which input errors are on the respective
questionnaire
Errors are shown with a message text and displayed on the respective input lines




SAP AG 2009/ 28
Side Step: Error Handling 3/3


If you leave a screen, the data is saved automatically. If there are errors, it is shown
on the next screen
If there are input errors, no results will be calculated at all

Input Questionnaire: User-Based Sizing Tables

3b




User sizing only considers concurrently active users

Most user sizings follow the standard pattern of low, medium, and high activity users
   Think times between screen changes of 5 minutes, 30 seconds, and 10 seconds
   The usual distribution is 60-70% low, 30% medium, 5-10% high
   If in doubt, take medium activity users

The user sizing result is independent of the throughput sizing result

  Per default, gross results are displayed for 'New system' (with minimal offsets). If you
  choose 'System extension‘, net results are displayed.
  On the project information questionnaire you can choose whether you want to see gross or
  net results on project, solutions, and software component result levels. This choice is
  saved for the project.
  Additionally, you can switch between 'New system‘ and 'System extension‘ on the result
  page for project, solutions, and software component result levels.
  All other levels show net consumption

Goal of the GoingLive Check: Sizing verification prior to going live
     Estimate the future workload on the system
     Based on information from Quick Sizer project

Prepare for the GoingLive Check
1.   Create a new Quick Sizer project
2.   If you already created a project
          Check your entries
             Set the status to "GoLive" in the status bar



The accuracy of the sizing verification depends on the correctness of the data you

For an initial sizing recommendation, proceed as follows
1        Call http://service.sap.com/quicksizing

2        Create a sizing project with the relevant information, such as number of users

3        Get an initial sizing result for CPU, disk and memory

4        Possibly apply additional guidelines on top

5        Check for sample configurations at www.sap.com/benchmark

6        Provide hardware vendor with Quick Sizer project name (and additional guidelines, if desired)

Conclusion


The purpose of the Quick Sizer is to give customers and prospects an idea about the
initial hardware size of the system necessary to run the proposed workload.

The Quick Sizer calculates resource categories for
   CPU
   Disk
   Memory

Sizing is an iterative process that continuously brings together customers, hardware
vendors and SAP.
