Almost every conversation about storage includes performance. That’s because storage system performance is important for the responsiveness of applications. Most vendors go to great efforts to provide performance data for their storage systems. This performance data provides valuable information for making decisions about deployment and how particular applications are used.
But the performance information must be credible for it to help make decisions. If the performance data is inaccurate or not applicable for the way the customer will use the system, that vendor’s performance data will be discounted by decision makers in the future. Vendor performance information is greeted with skepticism anyway. Producing inaccurate or inapplicable information quickly turns skepticism into distrust.
