Sizing for SAP GRC

Sizing for SAP GRC

Selected Factors That Influence the Performance

Landscape

Number and type (SAP, Non-SAP, IDM, etc.) of target/backend systems: for access risk analysis, access provisioning, role generation and/or superuser privilege management

Business Requirements

• Total number of objects (users/roles/profiles) in each of the backend system for access risk analysis
• Total number of risks and rules defined for access risk analysis
• Average number of permission level violations per object (user/role/profile) in access risk analysis
• Number of average roles per request and number of average systems associated per request
• Number of Firefighter IDs accessing the backend per hour during normal business hours and average number of transactions per firefighter
• Number of access request per hour or per working day and number of maximum concurrent users to create or approve request
• Number of maximum concurrent real-time access risk analysis (ad-hoc) jobs and average number of objects (users/roles/profiles) in each real-time access risk anlaysis
• Disk size depends on number of violations; frequency of ad-hoc analysis, etc. It will also depend on # of clients.

Assumptions for the Sizing Guideline

Sizing of Access Control v10 is based on the following assumption

• Out of the box access analysis rule set with around 50,000 rules are used in all access risk analysis
• Sizing of only AC v10 server is provided. It is expected plug-in installed in the backend system(s) will add some overhead when AC v10 retrieves data but this overhead in the backend system(s) is not included here.
• Preliminary sizing is performed on only a selected use cases including full batch access risk analysis
• Database is included within the sizing
• No network sizing is performed here
• Only T-shirt sizing is provided
  • Small - 1-3 backend systems with 10,000 users
  • Medium - Between 3 and 10 backend systems and 25,000 users
  • Large - 10+ backend systems with 50,000+ users

Preliminary Sizing Guideline for AC v10

Category	Minimum Disk Space	Minimum SAPs
Small	400 GB	2000 SAPS
Medium	600 GB	4000 SAPS
Large	1,000 GB	8000 SAPS
