Indexer Volumes(Disks) in a Smartstore configuration


Hi All,

It is recommended to use the i3.8xlarge instance type which comes with ephemeral storage for Splunk indexers if leveraging Smartstore for remote storage (per the Deploying Splunk Enterprise on Amazon Web Services tech note by Splunk). This ephemeral storage as I understand will hold the cached storage. What I’m trying to understand is how the good people here have set up there indexer to leverage SmartStore (S3) while also using an ephemeral disk(if at all) for local cache since the non-cache data (e.g., config files in /opt/splunk will be lost on a restart or reboot of the server).
- Are folks attaching an EBS volume for the indexer configuration? I feel like an attached EBS volume will undercut the cost saving of going the route of a smartstore somewhat
- Are they leveraging automation to accomplish a rebuild of the server each time it is restarted/rebuilt?
- What does your indexer setup look like while using SmartStore (i.e. Servertype (e.g AWS Server Type, Storage Volume(s), remote storage type

That’s the hole in my understanding as of the moment. Any clarification is highly appreciated.
