The CMDB CI Class Models app is the single source for all new base-system CMDB CI class models defined by ServiceNow.
The app provides customers and ISV partners with classes for the Discovery and Service Mapping Patterns apps.
Use the app to obtain and leverage newer class models at a faster pace than with regular family releases.
- Provides base-system CMDB class models for new resources
- Adds new classes and their descriptions to the CMDB class hierarchy
- Creates identification rules and dependent relationships for new classes
NEW
- Copied all IRE identification rules for the Hardware [cmdb_ci_hardware] table to the Computer [cmdb_ci_computer] table. In addition, we added a new identification rule based on the object_id field to Computer CI.
- Added wavelength attribute to the Network Interface class.
Wavelength is a list of one or more optical wavelengths in nanometers, each as an integer or decimal, separated by a comma and a space. By adding a Wavelength (nm) field, the network teams can immediately identify the correct transceiver modules and channel assignments in any multiplexer (WDM) or single mode / multimode environment, reducing configuration errors and speeding both deployment and troubleshooting.
- Added unit position attribute on the Equipment Holder class
Unit position identifies the position of the equipment on a shelf relative to the bay/rack identified in the Frame identifier code.
This attribute can be used to identify the equipment’s tray position, providing a clear location in the configuration. Example from data: “6A”, where “6” represents the shelf identifier and “A” represents the tray position.
- Added a new Network Function class (cmdb_ci_network_function_instance) under the Network Service Instance class (cmdb_ci_network_service_instance)
The Network function class enables better mapping of device communication such as routing, firewalls, and load balancing. This function is available in three types: physical, virtual, or container, reflecting its evolution from dedicated hardware appliances to modern, flexible software deployments.
IRE Rule: One IRE rule for Name, one IRE rule for Object ID
- Added a new Network Function Application class (db_ci_network_function_application) to the Application class (cmdb_ci_appl)
Network Function Application represents the software component that powers virtualized network functions (NFV). It captures essential application details to manage network workloads and enable integration with virtualized or containerized infrastructures
- DCIM Data Model: We are developing a Data Center Infrastructure Management (DCIM) solution that enables a comprehensive representation of the power, HVAC, and network infrastructure along with their interrelationships. This feature aims to create a unified and detailed data model for all critical data center assets and their connectivity, supporting better monitoring, power management, and planning.
Elements of this model include:
- cmdb_ci_rack_pdu (Rack PDU)
Device used to distribute electrical power to multiple devices within a server rack or data center. It provides efficient and safe power management by offering outlets for servers, switches, routers, and other networking equipment.
- cmdb_ci_rack_rail (Rack Rail)
Vertical metal components used in server racks or enclosures to support and secure equipment such as servers, switches, and other devices. They typically feature standardized hole patterns to accommodate rack-mounted equipment.
- cmdb_ci_wire_manager (Wire Manager)
Device or system used to organize and route cables in server racks, data centers, or other environments where numerous cables are present.
Power Equipment (All children of the Power Equipment Class)
- cmdb_ci_transformer (Transformer):
Electrical device used to change the voltage of AC in a power distribution system. It is crucial in power generation, transmission, and distribution networks, including those found in data centers.
- cmdb_ci_switch_gear (Switch Gear):
A collection of electrical disconnect switches, fuses, and circuit breakers used to control, protect, and isolate electrical equipment in a power distribution system.
- cmdb_ci_power_panel (Power Panel):
Essential component in electrical systems used for managing and distributing electrical power to various circuits and devices. It contains circuit breakers or fuses that protect individual circuits and allow for manual switching of electrical supply.
- cmdb_ci_rectifier (Rectifier):
Electrical device that converts AC current to DC current.
- cmdb_ci_inverter (Inverter):
Electronic device that converts DC current to AC current.
- cmdb_ci_maintenance_bypass_panel (Maintenance Bypass Panel):
Critical component in data centers and critical facilities. It allows for the maintenance or replacement of power distribution equipment such as a UPS without interrupting the power supply to connected loads.
- cmdb_ci_remote_power_panel (Remote Power Panel):
Electrical distribution device used in data centers and other facilities to distribute power to multiple devices or loads from a centralized source, such as a UPS or generator.
- cmdb_ci_circuit_breaker (Circuit Breaker):
Automatically operated electrical switch designed to protect an electrical circuit from damage caused by overloads or short circuits. When a fault is detected, the circuit breaker interrupts the flow of current, preventing further damage to the circuits.
- cmdb_ci_fuse_alarm_panel (Fuse Alarm Panel):
Monitor the status of fuses and alert operators when a fuse has blown or is faulty. It provides an early warning for maintenance personnel, helping prevent system downtime or damage to connected equipment.
Facility Hardware Class:
- cmdb_ci_cage (Cage):
Secured enclosure or space that defines a specific boundary for equipment or components. It's used to house servers or storage devices, offering both security and organization.
IRE rule: Add PID, Name on Cage table
- New Backup Management Features: This release introduces new classes for managing backup storage information and job execution history, including attributes such as backup status, execution logs, and recovery point objectives.
- cmdb_backup_storage_information (Backup Storage Information):
The (OT) Backup Management provides visibility and actionable insights on the backup of the OT devices. The class tables described below are interconnected and collectively form the Backup Management data model. Use the Backup Storage Information class to create backup records that identify the device in internal or external backup services.
- cmdb_backup_job_execution_history (Backup Job Execution History):
Use this class to capture a history of records for all backup executions.
UPDATES
- The label (display name) for the Video Management Systems [cmdb_ci_vms_appl] table was corrected (the incorrect label was the plural form: Video Management System).
- The Site column in the Video Management Systems [cmdb_ci_vms_appl] table is deprecated because a relationship to the Site table exists.
- For OT device: A new view has been introduced to display all OT Devices grouped by Managed Network.
Required plugins and products:
- Configuration Management Database (CMDB) (com.snc.cmdb)
