Nutanix Storage Replication Adapter (SRA) is a software module developed by Nutanix according to specifications defined by VMware. Nutanix SRA contains a set of scripts that uses the Prism REST APIs to interact with Nutanix clusters. The SRA is installed on the VMware Site Recovery Manager (SRM) server as a plugin that enables the SRM to perform “Array-Based Replication” (ABR) using Nutanix replication, data protection (DP) and disaster recovery (DR) functionality.   Figure 1 illustrates a simplified view of the topology of a typical DR solution built on Nutanix clusters with Nutanix SRA and VMware SRM and vCenter servers    Figure 1. Simplified DR solution built on Nutanix clusters with Nutanix SRA and VMware SRM and vCenter servers.   The DR solution consists of two sites: Protected Site and Recovery Site. The Protected Site is usually the Production Site; and the Recovery Site, the DR Site. Each site has a Nutanix cluster with 3 or more nodes where VMs are hosted with VMware ESXi being the hypervisor.
