The BVQ development team is currently working on the new BVQ dashboard functionality. This new dashboard should become available in 1H2015.
The dashboard is great for monitoring, you can open several dashboards and put them onto different screens, this will then be a complete storage control station.
Each of the different windows can be graped, zoomed out and used for any kind of analysis.
put different SVC or Storwize systems on different monitors or you just mix them - as you like.
BVQV3.3.2 has toleration support for V7.4 which means that everything is supported without the new V7.4 features encryption and child pools.
These will be supported with the upcoming BVQ V3.4
The BVQ story ...
The storage challenge
Even a small storage environment may be complex. Questions about cost optimization or availability are hard to answer because the knowledge about actual and future performance needs is often not available or not current. Analysis and help in case of performance bottlenecks is not possible because of missing tools or the available tools do not have the technical depth or are too complex to be used.
The start of the... [More]
It is a long time ago, that I added an analysis video to the wiki.
The following is a very nice situation where we had to find the reason for a very high load on a node port.

We are very proud to announce the general availability of BVQ Version 3.3.
BVQ Version 3.3 is the first IBM SVC and Storwize monitoring and analysis solution with full support of the IBM SVC and Storwize Family Software V7.3.x.
IBM SVC and Storwize Family Software V7.3.x enhances overall system performance by introducing a completely new cache architecture. With BVQ V3.3 we are now able to analyze this new cache architecture. This is highly essential, to better understand performance bottlenecks because many problem root causes can... [More]
This is a a new performance analysis whitepaper in the technical section of BVQWIKI
The unbalanced VDisk mirror problem
Many performance issues are caused by an unbalanced situation in the two sides of VDisk mirrors.
One finds, that a mirrored Volume runs into latency peaks which cannot be explained by the Volume behavior itself. The managed disk groups (mdg) in the storage backend show completely different load and latencies.
We have recognized that often the distribution of primaries can cause this problem.
Storwize Family Software V7.3 has implemented many changes, specially in the cache architecture, Easy Tier and re-striping of storage pools. The changes target to enhance overall system performance. The experience is good but sometimes little things can cause trouble and can lead to a deterioration.
What to do, if you have made this experience?
Try to find the reason and fix it!
We have just released the new BVQ V3.3 offline scanner for general download. This scanner can now also capture the new performance metrics of... [More]
Another new feature of the latest BVQ offline scanner allows to scan more than one systems at once.
This is especially helpful when you plan to use BVQ Copy Services Package to analyze Metro Mirror or Global Mirror connected systems.
A profile is created per Storage system, which is then used for this one system to separate the data. In this way, many different SVCs and or Storwize systems can be scanned at the same time.

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...

Read this ...
... if you haven´t planned a budget for storage analysis at the moment.
... if you just want to know what is happening in your SVC or Storwize!
... if you want to know more about the technical limits of your SVC or Storwize.
... if the word ‘Performance Bottleneck’ sounds very familiar to you.
We have developed a new type of scanner for BVQ and introduced it already to interested customers. The response was very enthusiastic and immediately there were a lot of requests for using this scanner... [More]
it's so easy ! We have already carried out the first analysis, in which we have used the BVQ offline scanner.
A big advantage was :
No need to install anything!
The process is so simple:
1 The offline scanner is downloaded from our website
2 The offline scanner is started and collects performance data
3 The collected performance data will then be sent to us and analyzed
In this way, we have solved various typical error situations for our customers.

The BVQ offline scanner is the method of choice to collect data for an BVQ analysis with installing any program
No complexity - It will run in less than 5 minutes!
This is the starting point for a free health check report!
Start this scanner on any server or laptop and let it collect data for some time. This data will then be sent to a central BVQ Server (SVA or Partners) where it will be run through an report engine. You will receive a risk report some days after you have sent us the data. We call this... [More]
