What do you mean by Sizing?
Sizing is a standard term in SAP, which means determining the hardware requirements of an SAP System such as physical memory, CPU power, and I/O capacity.
Determining sizing requirement ensures that customers purchase hardware as per their business need and also ensures lower cost and reduce TCO.
Sizing in SAP HANA:
The critical factor for SAP HANA implementation is the right sizing of the server based on the business requirement and this means correct calculation of amount of memory, the CPU processing power.
SAP HANA sizing consists of Memory sizing for static data
, Memory sizing of objects created during runtime (data load and query execution), Disk Sizing and CPU Sizing.
For the purpose of successful SAP HANA implementation, SAP has provided various guidelines and methods to calculate the correct hardware size.
We can use any of the below method:
1. SAP HANA sizing using the QuickSizer tool
2. SAP HANA sizing using the DB specific scripts
3. SAP HANA sizing using the ABAP report
In the later chapters we will study more about the sizing and these methods.
Product Availability Matrix (PAM):
All available SAP certified HANA hardware configurations can be looked up in the HANA PAM (Product Availability Matrix). In addition SAP also certifies additional configurations as required by customer scenarios. You should check with your hardware vendors and SAP Account Executive in case you are interested in any other configuration than listed in the HANA PAM.
