Sizing for SAP on Azure Projects

Introduction

Sizing for SAP on Azure Projects is all about determining the following:

  • Hardware requirements for your Virtual Machines (VMs) including:
    • Memory
    • CPU Power
    • Disk Space
  • I/O Capacity
  • Network Bandwidth

Sizing according to the type of SAP Project

Sizing for SAP can be broadly divided into three types:

  • Greenfield Sizing: It is the sizing of a fresh and new SAP instance
  • Brownfield Sizing: It is the sizing for an existing SAP Instance that will either be migrated to the cloud, upgraded, or re-sized
  • Expert Sizing: It is done based upon the tools provided by SAP. This is mainly used in complex sizing and is processed with the help of a sizing expert.

The above types will highly depend upon your use case:

  • If you have a new SAP System and you want to develop fresh implementations there, then it will be part of the Greenfield Sizing
  • If you have an existing SAP system and you are migrating it to the cloud, then you will need Brownfield sizing
  • If you have a current SAP Cloud system, and you plan to re-size them, then again, you will need Brownfield sizing

The above types are just to differentiate the sizing based upon your use case. The actual tools for sizing will be discussed next.

Sizing in SAPS

Sizing in SAP is known as SAPS. SAPS stands for SAP Application Performance Standard. SAPS is a hardware-independent unit of measurement that describes the performance of a system configuration in the SAP environment. Derived from the Sales and Distribution SD-Benchmarks, where 100 SAPS is defined as 2,000 fully business processed order line items per hour.

SAP came with SAP Standard Application Benchmarks which makes the sizing process easy. You can view the official page here. Here you can filter and understand where you will land in terms of sizing based upon your filter.

SAP Quick Sizer

SAP Quick Sizer is a free web-based tool built by SAP in partnership with platform partners such as Azure to help with sizing your SAP instance. You can check it out here.

Quick Sizer (classic / HANA) translates business requirements into technical requirements used for sizing. Quick Sizer is basically an online questionnaire that you work through, and it spits out sizing results.
