We are currently looking at the using clustering to introduce redundancy/HA into the deployment. I have a few questions which I may have missed in the documentation...
Thanks in advance, and I look forward to your help 🙂
I can help with a few of these:
Minimum number of peer nodes: Depends of course on your availability needs, but you can certainly set up a cluster with just two peer nodes.
Storage requirements: Many factors enter into it, but there's some pretty extensive documentation here: http://docs.splunk.com/Documentation/Splunk/latest/Indexer/Systemrequirements#Storage_considerations
