    Summary of Nutanix extension classes

    The Nutanix extension classes are provided by the CMDB CI Class Models store app, which adds or updates classes to extend the CMDB class hierarchy specifically for Nutanix infrastructure components. These classes include detailed descriptions, identification rules, and relationships to support managing Nutanix resources within ServiceNow's CMDB. They enable applications like Discovery and Service Mapping Patterns to populate Configuration Items (CIs) and discover Nutanix technologies and software effectively.

    The Nutanix Enterprise Cloud platform itself is a converged, scale-out compute and storage system that hosts virtual machines across clustered nodes managed collectively. Each node runs a hypervisor and includes a Controller VM that pools local storage.

    Key Features

    • New and updated Nutanix classes: The app introduces several Nutanix-specific CI classes such as Nutanix Prism Central, Nutanix Cluster, Nutanix Controller VM, Nutanix Storage Container, Nutanix Storage Pool, Nutanix Host, and Nutanix Virtual Machine Instance. These classes extend existing base CMDB classes like cmdbcivmobject, cmdbciappl, cmdbcistoragevolume, and others.
    • Detailed attributes for Nutanix resources: Several classes have been enhanced with specific columns relevant to Nutanix environments, including unique identifiers (UUIDs), configuration details (e.g., block serial numbers, hypervisor types, memory size), networking information (internal/external subnets), version information, and storage policies (compression, deduplication, replication factor).
    • Class hierarchy integration: These classes integrate seamlessly with the existing CMDB schema, allowing ServiceNow customers to manage Nutanix infrastructure with familiar CMDB tools and processes.

    Key Outcomes

    • ServiceNow customers can comprehensively model Nutanix infrastructure within their CMDB, improving visibility and management of virtualized compute and storage resources.
    • Discovery and Service Mapping can leverage these extended classes to detect and map Nutanix components accurately, ensuring up-to-date and accurate CI data.
    • Enhanced Nutanix-specific attributes enable more detailed tracking of cluster configurations, storage policies, node counts, and controller VM states, supporting better operational insights and automated workflows.
    • The availability of a centralized class for Nutanix Prism Central supports managing multi-cluster environments from a unified interface within ServiceNow.

    The CMDB CI Class Models store app adds or updates classes for Nutanix.

    The CMDB CI Class Models app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

    Nutanix Enterprise Cloud platform

    The Nutanix Enterprise Cloud platform is a converged, scale-out compute and storage system that hosts and stores virtual machines. All nodes in a Nutanix cluster share the management of cluster resources. The foundational unit for the cluster is a Nutanix node which runs a standard hypervisor and contains processors, memory, and local storage (SSDs and hard disks). A Nutanix Controller virtual machine runs on each node, enabling the pooling of local storage from all nodes in the cluster.
