Quick Sizer Tool

[PD11]

Hi All,

I need to go for User based sizing of SAP landscape through Quicksizer. I have SAPS, IOPS and CPU's. My Query is what is the relation among these. Please help.

Thanks and Regards,

Hi

Our out put is 2000 SAPS then whats our server Configuration?

May i know this configuration support 2000SAPS ?

Hi,

Quick Sizer will give you a indicative measure of CPU, which is defined in SAPS. This value is used by your hardware vendor to propose you the right kind of hardware. You can also refer to SD Benchmark certificates to see what fits your requirement. (http://www.sap.com/solutions/benchmark/index.epx)

I am assuming you have already gone through the documentation in the https://service.sap.com/sizing and SDN , what is SAPS and what is 2-tier/3-trier SD benchmark

Also the qiucksizer must have given you memory and disk capacity required.

The I/O's per sec helps you to choose the right kind of storage systems.

Also please remember quicksizer result is just an indicative value, you need to use your experience and knowlodge of business process to added to the above result. This becomes especially very important when you do not have throughput data and you have done user based sizing.

Hi,

For basic steps go to http://service.sap.com/quicksizing. Ref note 85524.

Not sure what you are looking for ... I got some answers from my friend. Here it is

The SAP Application Performance Standard (SAPS) is a hardware-independent unit that describes the performance of a system configuration in the SAP environment. It is derived from the Sales and Distribution (SD) Benchmark, where 100 SAPS is defined as 2,000 fully business-processed order line items per hour. In technical terms, this throughput is achieved by processing 6,000 dialog steps (screen changes), 2,000 postings per hour in the SD Benchmark, or 2,400 SAP transactions. In the SD Benchmark,

fully business-processed means the full business process of an order line item: creating the order, creating a delivery note for the order, displaying the order, changing the delivery, posting a goods issue, listing orders, and creating an invoice. In general SAPS is used to size CPU and memory of a SAP system.

In production systems, a rough analysis gives values between 0.5 to 0.6 IOPS per SAPS. Based on this rule an SAP system that needs to reach 10,000 SAPS at 100% workload should be assigned a storage system that can process 5,000 to 6,000 IOPS. The storage system's cache size can play a significant role in determining the disk (rotating) requirements. On the other hand, for EFD disks, the system's cache size is not an important factor.

Based on the conversion formula between IOPS and SAPS (0.6 IOPS per SAPS) it is possible to derive the IOPS required and hence the number of disks needed while sizing the SAP system.
