How to setup Splunk Multisite SmartStore with FlashBlade

This document will cover the object store setup on FlashBlade (FB) for Splunk SmartStore in a multisite environment. At this time, Splunk Multisite SmartStore deployment on S3 compliant object store like FlashBlade is limited to two sites, with each site hosted in an on-premises data center. In addition, Pure FlashBlade currently can only support object replication between two FlashBlades. Hence this limits the Splunk Multisite SmartStore on FlashBlade to two sites.

1. Minimum Purity//FB version required to support Splunk Multisite SmartStore: 3.3.3.
2. Purity//FB tunables required for bi-directional object replication as well as to enable the "multi-site-writable" bucket option. The tunables can only be set up by the Pure Storage support. Please work with the support to set up the tunables before proceeding to the Object Store Replication configuration.
   1. To enable the bi-directional object replication, the workload has to be qualified by PM and please follow the steps in this KB and make sure to apply these steps on both the FlashBlades.
