Following table describes the PowerFlex storage design. Multiple storage volumes have been carved out on the PowerFlex and PowerScale, these are mapped to Splunk Virtual machines.
Table 4. Storage design consideration
Instance role | Quantity | Operating System storage (GB) | Hot/warm bucket storage (TB) | Cold bucket storage (TB) |
Search Head | 1 | 300 | 0 | 0 |
Indexer | 2 | 300 | 1 | 3 |
Cluster master | 1 | 250 | 0 | 0 |
Forwarder | 1 | 250 | 0 | 0 |
Note 1: For this configuration, Splunk sizer recommends 750 GB per indexer for hot/warm data retention, but for this solution, 1 TB has been provisioned per indexer.
Note 2: For this solution, PowerScale cold data buckets have been carved out for four months retention period. But customers can configure it based on their needs and allocate storage appropriately.
