This is new for the upcoming Version 3 from BVQ (Nov 13)
BVQ can now scan on 1 minutes interval. It is incredible who much detail becomes uncovered when you scan on 1 minute.
Why does this matter?
A smaller scan interval will allow even deeper looks into the system.
The possibility to change these settings on the fly without any interrupt supports normal ands deep analysis mode.
To switch from 5 minutes to 1 minute is easy and does not need any special activity!
You just change the timing of the statistics collection on the SVC or Storwize.
There are limitations, when you run a SVC with many nodes. The SVC will probably not be able to collect all data in a 1 minute interval.
In this case you will recognize in BVQ that the presented scan intervals are not not consistently on 1 minutes.
This is a clear sign that the storage is not able to support this interval
