I just wanted to ask if there is a web site link for Splunk that you can use to estimate disk tuning. Let's say, for example, I will use 3 indexers with 2TB each. This page will show you what are the other requirements needed. It's like a page to tweak your Splunk setup. I used it before, but I was unable to bookmark the site.
Always look at the small prints as well; the footer of the page:
This sizing application is not supported by Splunk.
