Scaling out splunk environment

[yuwtennis]

Hi!

I would like to ask question for the scale-out process for splunk.

I am considering to build the splunk on single server but bit concerned
when to scale out server as search-head and peer node.

Are there any numbers, perhaps thresholds, which you may need to be aware of?
I would appreciate if someone can share their thoughts.

Thanks,
Yu
