Final answer:
Splunk supports up to 64 sites in a multisite indexer cluster for recent versions, which is crucial for data high availability and disaster recovery.
Step-by-step explanation:
The maximum number of Indexer cluster sites that Splunk supports depends on the version of Splunk you are using. For most recent versions, Splunk has documented support for up to 64 sites in a multisite indexer cluster, which enables high availability and disaster recovery. Each site in a multisite cluster can have multiple indexers, and the architecture is designed to keep your data safe and accessible even in the event of site failure.
Configuring a multisite indexer cluster requires careful planning, as you need to consider factors such as replication factor, search factor, and the amount of data you need to index. Furthermore, understanding the deployment's physical geography is crucial for optimizing the performance and resilience of the cluster.
