Nutanix Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by usingTags.Tags are a component of Nutanix Era that allows users to assign custom metadata to various entities, enhancing the ability to organize, search, and manage these entities within the Era platform1.

The Global Service Level Agreement (SLA) feature of Era allows an administrator to create Time Machine policies in a Multi-Cluster configuration1.This feature provides a unified way to manage and enforce backup and replication policies across multiple clusters, ensuring consistent data protection and recovery across the entire environment1.

An NDB Software Profile is a template of the OS and database engine that you can use to provision or clone database server VMs using NDB. To create a software profile, you need to upload an installer package for the database software that you want to use, such as SQL Server or Oracle. The installer package must be compatible with the OS image that you have registered with Prism Element. You do not need a database server VM registered with NDB, a patch file for the installed databases, or an OS image registered with Prism Element to create a software profile. Those are required for other tasks, such as creating a software profile version, registering a database server VM, or provisioning a database server VM.

In the Nutanix Database Automation (NCP-DB) framework, provisioning a new Oracle database through Era requires the configuration of both a Compute and a Storage profile1. The Compute profile is used to define the resources allocated to the database, such as CPU and memory, while the Storage profile is used to specify the storage configuration for the database.These profiles are essential in ensuring that the database is provisioned with the necessary resources and storage configurations for optimal performance23.

In the context of Nutanix Era, the term ''Brownfield Database'' is used to refer to an existing database that is registered with Era1.This process allows Era to bring Database as a Service (DBaaS) capabilities to your existing database2.It's important to note that before you register a database with Era, certain prerequisites must be met3.
