Sizing Goals in different phases of a customer project
1. Very early to plan hardware expenditures
2. A few months before live start to verify assumptions
▪ Determine the overall performance requirements
3. During production stages to ensure operations and verify/adjust estimations made earlier. ”Trigger events” include:
▪ Upgrade database, operating system, SAP application
▪ Reconfigure system landscape
▪ Change business process
▪ Rollouts: more users or other load

Different Types of Sizing
Greenfield Sizing
Sizing of new applications from scratch
Brownfield Sizing
Extension / migration of an SAP system
Bluefield Sizing
Re-implementation of an
existing system
Hardware Budget Sizing
Smaller companies
▪ Tools: Sizing Guidelines, Quick Sizer (user)
▪ Very simple algorithms
▪ Assumptions, likelihoods
Medium to large companies
▪ Tools: Sizing Guidelines, Quick Sizer (throughput)
▪ Usage of standard tools
▪ Focus on core business processes
Re-Sizing
▪ Tools: SAP system monitors
▪ Goal: Extend an existing system by load
− e.g.,100 additional users who'll do the same as the current productive
Selective Data
Transition*
▪ Tools: S/4HANA & BW/4HANA
Sizing Reports
▪ Re-Implementation with
Selective Transactional Data
* Special case
Shell copy: Re-implementation
without transactional data, but with
old customizing and master data
Upgrade Sizing
▪ Tools: SAP system monitors
▪ SAP Notes
▪ Goal: Upgrade SAP software
Migration Sizing
▪ Tools: S/4HANA and BW/4HANA Sizing Reports
▪ Goal: Migrate ECC or BW system to S/4HANA or BW/4HANA
Delta Sizing
▪ Tools:
− SAP system monitors
− Sizing Guidelines, Quick Sizer for additional load
▪ Goal: Extend an existing system by new functions
− e.g., you are live with SAP S/4HANA and want to add SAP EWM or
SAP S/4HANA embedded analytics

Finding the correct sizing approach
Greenfield, Bluefield (flavor of Brownfield) and (real) Brownfield Sizing
Customer needs to size systems
running on SAP S/4HANA / BW/4HANA
Net new SAP S/4HANA application Existing SAP system fully
converted to SAP S/4HANA / BW/4HANA
New Implementation approach
“Greenfield Sizing”
Re-Implementation with Selective
transactional Data
"Bluefield Sizing“ *
Find deployment options:
Connect with hardware vendor and check for
configuration
Certified and Supported SAP HANA®
Hardware Directory
Link:
Existing SAP system converted to SAP
S/4HANA via Selective Data Transition
System Conversion approach
"Brownfield Sizing"
Use SAP HANA-based Quick
Sizer / Sizing Guidelines
Use Sizing Reports/ Procedure

Assumptions
• The system is properly tuned for optimal performance
• The focus is on net consumption of business processes on the hardware
Note: Resource consumption strongly depends on
• Business process: customizing, customer extensions
• Combination of hardware and software: configurations
• Recommendations refer to used resources, not allocated ones
Introduction – Sizing Approaches on Productive Data
Upgrade Sizing
All projects
▪ SAP system monitors
▪ SAP Notes
▪ Goal: Upgrade SAP software
Re-Sizing
All projects
▪ SAP system monitors
▪ Goal: Extend an existing system by load
− e.g., by volume 100 additional users who'll do
the same as the current productive ones
Delta Sizing (combination
brownfield/greenfield)
All projects
▪ SAP system monitors
▪ Goal: Extend an existing system by functions
(e.g. new sizing with Quick Sizer)
− By different functions, e.g., you are live with CRM
and want to add SCM
