After checking the analysis results, you can use the What-if Analysis page to do additional calculations, to plan for future requirements or alternative scenarios.
You can vary the parameters and recalculate the results according to different criteria. For example, you can vary the network bandwidth parameter to see what effect it would have on the SRL size. Or, you can specify a potential SRL size and see how much network bandwidth would be required for that SRL size.
Note: |
Before specifying the network bandwidth, you must also consider the loss of available bandwidth due to the TCP-IP/UDP headers, because VRAdvisor cannot manage this. |
What-if Analysis also enables you to vary the percentage of disk writes as compared to the sample of data that was analyzed. For example, if you anticipate that your future needs will involve twenty percent more disk writes, set the percentage of disk writes to 120% and recalculate.
To recalculate results using the What-If Analysis
Select the appropriate option on the left side of the What-If Analysis page to recalculate results, as follows:
Calculate SRL Size for a specified Network Bandwidth and Outage.
Calculate the Network Bandwidth for data loss specified in bytes.
Calculate Network Bandwidth for data loss specified in time duration.
Calculate Network Bandwidth for Bunker and RTO.
