Hi,
I'm trying to understand the variables involved in a vSphere Replication between sites through a WAN link and if is there a better way to estimate the data transfer speed.
Here are what I know, so far, based on research and previews replication tests:
Below are the scenario and the results I got from a previews replication test
The data transfer speed was approximately 11GB/h
Note:
Any comments or shared experience will be appreciated.
Thanks
Everton
Have you looked at the the VR bandwidth calculator? http://www.vmware.com/vrcalculator
You can also look at the VMware Labs Replication Capacity Planning Appliance: https://labs.vmware.com/flings/vsphere-replication-capacity-planning-appliance as a way of determining bandwidth needs.
The best way to determine data transfer speeds would be to run actual replications as you have. Make sure that you look at both the initial full sync and the ongoing transfers.
Thanks gs_khalsa
Yes, I used the VR bandwidth calculator, but it didn't provide the information that I'm looking for.
I'll test the appliance that you recommended and compare the results with my actual replication.
I'm trying to understand if the numbers that I got (bandwidth utilization, data transfer speed, time to complete a initial synchronization...) are accurate/expected for my scenario and, if it is not, what may I need to looking for to adjust/improve that.
