Use of Capacity Estimates from zPCR
The information contained in the zPCR tool and documentation has not been submitted to any formal IBM test and is distributed on an "as is" basis without any warranty either expressed or implied. The use of this information or the implementation of any of these techniques is a customer responsibility and depends on the customer’s ability to evaluate and integrate them into the customer’s operational environment. While each item may have been reviewed by IBM for accuracy in a specific situation, there is no guarantee the same or similar results will be obtained elsewhere. Customers attempting to adapt these techniques to their own environments do so at their own risk.
Performance data contained in this document was determined in a controlled environment; therefore the results which may be obtained in other operating environments may vary significantly. No commitment as to your ability to obtain comparable results is any way intended or made by this release of information.
zPCR estimates have a degree of error of +/- 5%. Customers using zPCR information are solely responsible for building capacity plans using zPCR results which accommodate the degree of error inherent in the tool.
