You need to collect the data write samples that can be used with the VRAdvisor Wizard.
Best practices:
Veritas recommends that you collect the sample data using the volumes that are part of the Volume Replicator configuration that you plan to set up.
To collect a representative sample of data, it is recommended 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.
VRAdvisor calculates an optimum size of the Storage Replicator Log (SRL) and the network for your Volume Replicator configuration using a sample of the write statistics.
Depending on the operating system on which you collect 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.
