When collecting the sample of data, observe the following best practices:
We recommend that you collect the samples of data using the volumes that are to be part of the VVR configuration you are planning to set up.
To collect a representative sample of data, we recommend that you collect the sample of data over a period of 7 to 14 days.
Make sure that the collection period includes times of peak usage for your application, so that the collected data reflects your actual requirements.
In a shared disk group, collect a sample of data on each node. Start the collection at the same time on each node, for the same period. The resulting files can then be analyzed together.
VRAdvisor calculates an optimum size of the Storage Replicator Log (SRL) and the network for your VVR configuration using a sample of the write statistics.
Depending on the operating system on which you are collecting data, you can either collect the sample of data using the VRAdvisor wizard, commands, or the data collection script. For details, refer to the section for your platform.
