Performance analysis and monitoring for IBM SVC and Storwize

 



 

There is a difference in resolution and detail, whether one looks at the data using BVQ Web Monitoring Dashboards or the BVQ GUI for analysis.

The analysis has more possibilities and in this case it also works with the change volumes that are even more sensitive to changes than the actual volumes.
In this case, you can see in the analysis that the 10 minute cycle period was able to finish at 10am while the cycle was missed at 11:00.
This is just a detail, but shows that the results of the monitoring are already very good and can only be improved with very deep analytical methods.


Pict. 1: Compares the output of the BVQ analysis GUI with the monitoring dashboard.

The GUI analysis has the better resolution and more in-depth metrics; therefore can get more details from the situation.
But you can also see that the monitoring screens deliver a very good result.



Monitoring the cluster / cluster connection


Pict. 2: Shows the traffic between clusters –Data Rate write (blue) and latency (red)

 

Another advantage of the GUI is that it also allows the connection between two clusters in a GMCV relationship. In this example, you can see the data rate write from Cluster1 to Cluster 2 in  blue and the latencies in red.
This picture shows aggregated performance across all ports and can be used very well for planning. This is possible for FC and IP ports

From here you can break up the aggregate to the single port performance and even go from the port to the volumes that can use this port.
This is very useful when you see an unexpected load peak and want to quickly find out who generates this peak load.
This is where the analysis starts   BVQ offers the analysis favorites for Global Mirror with Change Volume.

 

Deep look into the topology


 

The BVQ Treemap shows the topology of the systems.
Here you can see the topology of the consistency groups down to the detail of individual copy relationships and the flashcopy mappings.
This makes all the secrets of the Global Mirrors transparent.

Monitoring uses this topology to be able to display current data at any time. If a disc is added to a consistency group, it is immediately perceived by the monitoring and classified correctly.
