Hello to all SVC and Storwize V7000 administrators
I would like to collect and share information about BVQ Business Volume Qualisicion in this blog. BVQ has been developed by SVA since 2008 to improve storage efficiency and lower storage costs in SVC environments. Everybody knows that SVC is a great product – it works and delivers! But nobody knows whether SVC is running in an optimal way. I like to compare the situation of SVC administrators with being forced to always be in motion in a dark room. Rule 1 – MOVE IN ANY POSSIBLE DIRECTION DON’T STAND! Rule 2- NEVER TOUCH A WALL! Understandably... [More]

calculate max of what storage is capable of achieving in terms performance behind SVC or Storwize V7000
Hello, I have
uploaded a new file to developer works. This was part of a so called performance
workshop we did for one of our customers. (If you are interested in BVQ or need help for an analysis with BVQ then please send a note to bvq@sva.de We offer this product or service around this product world wide) File: Foil Set for this blog entry One of the
questions was about the performance of the underlying storage infrastructure. In this case it was a DS5300 with plenty of 15k drives. So a plenty of performance
you can get out of this. We... [More]

new BVQ Use Case: Cost effective Storage planning
Use Case Target A 40 TB mail system has to be moved from an oversized 10k, 300GB storage to a
new storage environment with lower cost 7.2k, 1TB disk drives and Raid 6. The
question is how many disks are needed in the new 7.2k disk arrays to deliver
the same performance as before. With BVQ we are
able to analyze the aggregated performance values of all Volumes, which make up
the mail system. find more here: http://bvqwiki.sva.de/x/BYA6 pdf whitepaper download

Performance Bottleneck Analysis on IBM SVC und IBM Storwize
BVQ Use Case: Performance Bottleneck Analysis on IBM SVC and IBM Storwize Latency peaks, even if they are intermittent are dangerous troublemakers and you need targeted methods to track them down and to prevent them. This White Paper presents such methods for the IBM System Storage SAN Volume Controller (SVC), or IBM Storwize V7000 which also uses SVC code. As an analytical tool BVQ (Qualicision Business Volume) is used because it is very interactive and can evaluate the metrics provided by SVC very completely. Some pictures... [More]

2.5 Minutes Movie - Check SVC Cluster Nodes for overload Conditions
I have added a great movie that shows how we check a SVC or Storwize V7000, Storwize V3700 Storage for CPU or Global Caches overload. With BVQ you only need seconds to find out whether the storage is overloaded or not. This video shows how to do this. Link to the Movie Page

Video Analyze Volume performance issue (7 min)
This is from a customer situation in the week from September 17, 2012 severe performance issues have been detected on several hosts in the VMware Farm. A first analysis showed that one of the responsible discs has been ESX_D37. The problem was especially high on Monday from 10 AM to 1 PM. We want to analyze the situation on Monday to find out with the problem was coming from This Analysis will cover the following look into the performance of a volume - very simple - only volume IOPS and volume response times but good enough for this purpose...

best practice - how to save a lot of money when you want to extend capacity for your SVC or Storwize
This white paper is an excerpt of a customer analysis. The
customer wanted to know about the optimal strategy for future capacity
growth. He was running out of disk space in his high performance class
and needed a quick solution here. He also wanted to replace all his old
DS4700 systems and again the question is to solve, where to put this
data. A good way to approach this is a BVQ Storage Tier
Analysis because this perfectly shows which kind of performance demands
the customer has. The Storage Tier Analysis can be used to find... [More]

Analysis of a completely overloaded SVC See the complete Story here Customer Use Case: Analysis of a completely overloaded system I
added this document because I have never seen such results before. The
Storage has real performance Issues and it is easy to see that there is a
big problem to get the data written down from the SVC caches to the
backend storage. A Case where I believe that the storage backend has to
be exchanged with something that performs better. Technically the used
storage should be able to support all... [More]
