I just finished an performance bottleneck analysis for an 8 nmode cluster with several 100 TB and found one thing which I think might be a commonly made mistake in many of the bigger SVC environments. This picture shows the MDisk performance of SSD storage which is not acceptable. We have 37 ms latency on 37000 IOPS which is a bad value for this technology.
This picture shows one common reason, for bad storage performance whilst SVC and the backend storage look bored.
BVQ can help to find the reasons for these kind of problems and show... [More]
Win a SVC / Storwize analysis for free
What I can give for free, when you find the correct answer to this question, is an analysis of your SVC or Storwize.
You just need to find the correct answer to the question "what kind of measurement we see here".
You also need to solve correctly what the reason for these peaks have been.
Just answer by responding to this article or send a mail to email@example.com

... 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]
You love the comparisons of before and after?
I normally do not believe them. With one exception, which I myself have experienced.
The same Storwize system, before and after the weekend!
The customer had a time of suffering for more than 6 months until we set out to analyze his Storwize. We started on a Wednesday and after only some hours we knew what had to be done. The following weekend was used to carry out the changes.
These are the results: (See pictures below)
No wonder that our customer was more... [More]
There are so many possible reasons for availability risks in a storage system. It Is best to lower or turn off these risks by closely monitoring the most critical areas.
For a limited time we offer you an analysis of your storage system without effort, without installing a program and without risks and costs.
This service is available for SVC or Storwize storage.
How does it work?
Download the offline scanner app (java app) and use it to collect technical data
Send the data to our reporting... [More]
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.
The BVQ Node / Cache / SAN analysis is well suited to find vulnerabilities and performance bottlenecks in SVC / Storwize or in the SAN.

A ctually, this is a very simple question: "why buy expensive storage, if it is possible to achieve the same with a much cheaper storage?"
This sounds very reasonable, but often it is just difficult to implement. Let´s have a closer look on a typical top level target system for storage planning:
