I am currently assessing the options for indexer storage architecture.
I was reading the SVA and it had below statement for Classic Indexer Architecture Using File System Storage
This architecture is recommended when you have requirements for either
• Short-term data retention (<=3 months) or
• Long-term retention and performance-critical search use cases that frequently access older historic data
whereas, SmartStore Indexer Architecture Using Object Storage
This model can have significant positive impact on the TCO of your Splunk deployment, especially when you retain data for long periods of time.
There's a bit of ambiguity between both statements.
Our retention period is up 3 months and ingest roughly 1.5 TB per day. Mainly have ES, key Dashboards and reporting for which we need data worth the last 3 months. Environment will be in AWS (Not Splunk Cloud).
Based on this and the above two statements, I am confused which might be a better option to go for.
Both are good options. The second improves on the first by reducing the amount of file system storage needed - saving money.
