ESXi vSphere Replciation> Impact on CPU

Hi Team , I need to plan for an extensive DR cut over excersize  , and more specifically , make sure I have enough hosts available to re-seed/restart my replication jobs.

During re seeding , you can see checkum processes running using VIM-CMD HBRSVC commands .I want to know what the impact will be on my host CPU .

In old days , all VMware Kernel processes ran on the Hosts CPU0 , so it was easy to plot out Kernel based load.

This has changed 🙂

Using ESXTOP on ESXi5.1 , how can I see how much load I am causing when vSphere replication is doing a Checksum and receiving tons of data from its local VR appliance ?

We are planning to re - seed MANY replication jobs at the same time , and want to spec enough hosts to handle this .

I know the obvious processes , like HOSTd and vpxa , usb and so on , but is there a seperate process for replciation checksums ? If so , what is it called , and I assume it will be scheduled on any logical/available/physical CPU ?

Any inputs will be greatly appreciated .
