Cloudian provides software-defined, S3-compatible object storage solutions. Its Hyperstore software runs on CentOS or RHEL servers or as a pre-installed appliance, deployed on physical servers or virtual machines.

Prerequisites

• The target device must respond validly to the /bin/systemctl status cloudian-s3 command, confirming it hosts a Cloudian HyperStore Storage System; otherwise, it is discovered as a generic Linux server.
• SSH credentials configured for the Cloudian Storage Server must allow Discovery access.
• The MID Server must have network access to the target device.
• Discovery user privileges must permit necessary command execution.
• The following plugins must be installed:
  • CMDB CI Class Models plugin (version 1.31.0 or later)
  • Discovery and Service Mapping Patterns plugin (version 1.0.84 or later)

Credentials

Since Cloudian Hyperstore Software runs on CentOS or RHEL, credential configuration aligns with Linux server standards. SSH credentials must be set up accordingly to enable Discovery access.

Running Discovery

Discovery is performed by creating a schedule targeting the Cloudian Storage Server’s IP address using the configured SSH credentials. The Cloudian probe executes the /bin/systemctl status cloudian-s3 command to verify the presence of Cloudian HyperStore Storage System.

Data Collected

Discovery collects data across multiple configuration items (CIs) related to the Cloudian Storage environment, including:

• Storage Server: Details such as name, serial number, IP, manufacturer, model, OS version, CPU specs, and memory.
• Disks: Attributes like device ID, storage type, size, manufacturer, and model, linked to the storage server.
• File Systems: Information on size, free space, mount points, and relationships to disks and storage servers.
• Network Adapters: Network configuration details including IP address, netmask, MAC address, and association with storage servers.
• IP Addresses: IP details linked back to network adapters.

Classification and CMDB Integration

The Cloudian probe is integrated into the Unix-Classify Multiprobe and runs before the Linux classifier to accurately identify Cloudian servers. Once classified, records are created in the cmdbcistorageserver table, triggering the Cloudian Storage System pattern.

This classification ensures that Cloudian storage components are properly represented in the CMDB with accurate relationships and attributes.

CI Relationships

The discovery populates relationships reflecting ownership and containment:

• Storage Server owns network adapters and IP addresses.
• Storage Server contains disks and file systems.
• Storage Server virtualizes VM instances.
• Disks provide file systems.

What This Enables for ServiceNow Customers

By deploying these discovery patterns and prerequisites, customers can automatically and accurately identify Cloudian storage infrastructure components, their attributes, and interdependencies within the CMDB. This supports improved asset management, service mapping, and operational visibility of Cloudian storage environments integrated with ServiceNow’s ITOM capabilities.
