    Summary of Nutanix extension classes

    The CMDB CI Class Models Store app extends the ServiceNow Configuration Management Database (CMDB) by adding and updating classes specific to Nutanix infrastructure components. This extension enriches the CMDB class hierarchy with Nutanix-specific classes, descriptions, identification rules, and relationships, enabling better management and discovery of Nutanix assets within ServiceNow.

    These Nutanix classes can be utilized by applications such as Discovery and Service Mapping Patterns to accurately populate configuration items (CIs) and map Nutanix technologies and software.

    Key Features

    • New Nutanix Classes Added: Including Nutanix Prism Central (multi-cluster manager), Nutanix Cluster (physical node clusters), Nutanix Controller VM (storage management VM), Nutanix Storage Container, Nutanix Storage Pool, Nutanix Host (physical hosts), and Nutanix Virtual Machine Instance.
    • Class Extensions: Each Nutanix class extends relevant base CMDB classes (e.g., Virtual Machine Object, Application, Storage Volume) to integrate seamlessly into the existing CMDB structure.
    • Class Attributes: Several Nutanix classes have custom columns added to capture important technical details, such as cluster UUIDs, serial numbers, subnet information, versions, hypervisor types, memory allocation, replication factors, and compression settings.
    • Versioned Releases: The app has been updated over multiple releases, progressively adding new classes (e.g., Nutanix Prism Central in release 1.6.0) and enriching existing classes with additional attributes.

    Key Outcomes

    • Improved Visibility: ServiceNow customers gain detailed and structured visibility into their Nutanix infrastructure components within the CMDB.
    • Enhanced Automation: Discovery and service mapping processes can leverage these class extensions to discover and model Nutanix clusters, virtual machines, storage elements, and their relationships accurately.
    • Accurate Configuration Management: Capturing Nutanix-specific metadata such as cluster IDs, hypervisor types, and storage policies supports better configuration tracking and operational decision-making.
    • Seamless Integration: The Nutanix classes extend standard CMDB classes, ensuring compatibility with existing ServiceNow workflows and reporting.

    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.

    See the full release notes for all CMDB CI Class Models.
