Splunk Cluster Master and Search Head System Requirements

[micatcloudon]

Hi,
We plan to deploy the Splunk cluster and migrate our stand-alone indexer server.
While the requirements for Cluster Node are obvious, its not clear to me what Master and Search head server should be like in terms of CPU, RAM, IO.
Is there any formula I can calculate it per our current indexed data size and search rate ?
Thanks !

Not clear answers, but maybe following URLs help you to estimate hardware requirements for Indexer node and Search head.
