Explanation
To enable iSCSI connections between the Nutanix Database Service (NDB) server, Controller VMs (CVMs), and Prism Element, a Data Services IP must be configured in Prism Element. The Data Services IP acts as a cluster-wide address that facilitates iSCSI target discovery and connectivity. It is used by Nutanix Volumes (a block storage service) to present storage to external clients or services, such as the NDB server, via the iSCSI protocol. This IP ensures that iSCSI traffic is routed correctly and remains available even if a CVM fails, as ownership of the Data Services IP can move to another CVM in the cluster.
