Use BVQ to optimize SVC and Storwize in multi IO group clusters
Abstract (The whitepaper is in draft mode!)
The experience with the analysis of multi I/O group clusters always show the same kind of problem. Technical resources in larger SVC or Storwize environments are often utilized very unbalanced. This leads to performance bottlenecks in some areas of the system whilst other areas are totally underloaded. These kind of performance bottlenecks are often very hard to understand without using appropriate tools and the help of deeply skilled people. This white paper shows how you can recognize the unbalanced situation, and what to do to improve them.
Uneven utilization of SVC / Storwize hardware
The following is a typical situation, which we often find in larger SVC and Storwize environments with more than one I/O group.
So some technical resources are utilized very low some are all time overloaded and may provoke performance bottlenecks.
The complexity of such an multi IO group environment is such high that it is hard to understand when they are administrated without appropriate tools. This leads to high investments, blind problem shooting and possible frustration.
