Optimizing Performance Across Systems and Storage – Best Practices with TeamQuest
by Taneja Group

Important applications demand good performance. And most applications important to a business – mission—critical production, live customer, business operational, user productivity, external collaboration, et.al. – are dependent not just on server performance, but on storage performance too. Unfortunately, because most performance management approaches are IT silo—focused, it is difficult to assure end—to—end performance for key applications that are heavily dependent on resources drawn from multiple IT domains.

In this paper, we’ll briefly review the challenges to assuring good performance in today’s competitive IT environment, and discuss what it takes to overcome these challenges to deploy appropriate end—to—end infrastructure and operationally deliver high—performance service levels.

Reevaluating “Evaluating Scalability Parameters: A Fitting End”
by Dr. Jayanta Choudhury

Dr. Jayanta Choudhury takes a closer look at a methodology to estimate the parameters of Super-serial Scalability Law (SSL) which was reported by Dr. Neil Gunther in 2001. This article focuses on predictions for maximum performance for some example data sets which showed significant conflict with data reported from “Evaluating Scalability Parameters: A Fitting End.” The root cause of the error in prediction is analyzed. Dr. Choudhury provides an improved and correct methodology to estimate the parameters of SSL. The effectiveness of the improvement is demonstrated by applying the new corrected methodology to example performance data.
