Description of the performance problem solved in this document Latency problem was reported for VDisk CA-CL1-Disk04-N at 02/05/15 8:09, The environment are two clusters connected with Metro Mirror. The first aim of this document is to show how we found the root cause of this problem in the link between the two clusters. The second aim of this document is to describe how the root cause for this problem was found by using the BVQ structured performance problem analysis method. It demonstrates that successful analysis work needs a structured... [More]
Today Microsoft released Windows 10. If you're using BVQ and ask yourself about the support of BVQ in Windows 10 here's the answer: As of BVQ version 3.5.1, which will be released soon, the GUI modules (BVQ GUI & BVQ Reporting) will be supported with Microsoft Windows 10.

I'm going to be in Las Vegas from Feb 22 until Feb 27 to visit the IBM Pulse conference. This is a pretty good time to meet and talk about BVQ business opportunities. Or do some technical deep dives into the inner world of SVC or Storwize performance characteristics. Who ever is interested on meeting - just send me a note. Michael.Pirker@sva.de Until then Michael

As a request from one of our customers, we created a new metric called Overallocation coverage in BVQ version 5.3.1. Basically this is the ratio of over-allocated thin/compressed capacity covered by a pool or cluster: What is the advantage of having this metric? It shows very easily how well the space efficient VDisks are covered by storage capacities. In some cases, especially in very static environments, you know that you do not need this coverage. This value may then be small. However, in more dynamic environments, storage requirements... [More]
The intention of VDisk copies is to protect servers against hardware failures. For this reason, it is important that the mirrors of the VDisk copies are stored on different storage systems. Here are some additional challenges in system administration and system monitoring. This document describes how to ensure that all volumes are stored on different sites. An wrong setup in this area can lead to an only 50% chance of surviving a fail over. If there is a mirrored pair on Site 1 and by an evil coincidence an another on Site 2 you have the... [More]

Last week, 15th February 2017, 2 BVQ versions (5.0.3 & 5.1.2) have been released. All of the new features explained in earlier posts ( Multiple view composition, Self explanatory favorites, Fully recallable table views) are available in the BVQ GUI. You can find a summary of all new features, improvements & bugfixes here: https://bvqwiki.sva.de/display/BVQ/BVQ+5.0 In version 5.1 we introduced our new MongoDB database backend in BVQ. In version 5.1.x MongoDB is only available for new installations. A migration process from... [More]
How analysis windows support storage performance analysis (and make it by factors faster) BVQ version 5 introduces a new interface which allows the grouping of logically connected views into dashboard-like analysis windows. These groupings can then be stored as favorites and can be used like recipes to help solve problems quickly. The following picture shows an analysis window which gives an overview of a complete storage system. This analysis window describes the data path and the load in the hardware in a way that allows for... [More]
Let's talk about great analysis power! But first: What is the difference between a dashboard and a technical dashboard? You have probably seen my post about the Grafana dashboard https://www.ibm.com/developerworks/community/blogs/BVQ/entry/See_this_at_Edge_2016_Performance_data_graphical_visualization_for_SVC_and_Storwize?lang=en "This is what changed the world of storage performance analysis!
