JSON Breakdown

The regatta object contains a nodes key whose value is a list of JSON objects. Each object in the nodes list includes two key-value pairs: the node’s internal IP address and a list of dedicated NVMe devices present on that node.
  • internalIp – The host’s internal IP address used for inter-node communication. This assumes you have an internal network for all nodes in the cluster. If that is not the case, you can put an external IP here instead.
  • diskPaths – A list of objects, each containing a path key paired with the absolute path of a storage device on that node.
Each block storage device is defined as a separate JSON object within the diskPaths list. The devices can be of any type, not necessarily NVMe.
