    Key Features

    • Storage Disks: Information includes the name, computer reference, interface type, size, free disk space, manufacturer, and model ID.
    • File Shares: Includes the name and path to the file share for easy identification.
    • Storage Pools: Data encompasses the name, size, free space, and hosted by reference for managing storage capacity.
    • Storage Ports: Details include the name, unique Worldwide Port Name (WWPN), and speed for connectivity analysis.
    • Storage HBAs: Captures the name, model ID, and computer reference to track host adapters.
    • Storage Servers: Information includes the name, manufacturer, model ID, operating system, OS version, and a short description for server management.
    • Storage Volumes: Covers the name, unique object ID, state, size, and type of storage volume.

    Key Outcomes

    Discovery establishes relationships among storage components, such as mapping Network-Attached Storage (NAS) devices with client servers. It accurately resolves hostnames to IP addresses for both NAS file shares and Storage Area Networks (SAN), enabling effective management and utilization of storage resources across the organization. This comprehensive mapping ensures that storage relationships are maintained, providing insights that assist in optimizing storage performance and capacity planning.

    Discovery identifies and classifies information about storage devices.

    Storage relationships

    Discovery establishes the correct relationships between Network-Attached Storage (NAS) storage devices and remotely mounted client servers that consume the storage. Discovery maps NAS file shares. It maps by taking the IP or hostname of a remote mounted disk on the client computer. It then matches it to the IP or hostname of the storage server providing the exported file system.

    Discovery creates the following relationships for storage CIs running on Storage Area Networks.

    Table 8. SAN CI relationships
    Parent Component Relationship Child Component
    Storage Volume [cmdb_ci_storage_volume] Exports to::Imports from Fibre Channel Disk [cmdb_ci_fc_disk]
    Storage Volume [cmdb_ci_storage_volume] Exports to::Imports from iSCSI [cmdb_ci_iscsi_disk]

    Discovery maps NAS file shares. It maps by resolving the hostname of a remote mounted disk on the client computer to an IP address. It then matches it to the IP address of the storage server that provides the exported file system. Discovery extracts the hostname or IP address from the NAS path to determine the identity of the storage server. If the hostname is an actual hostname, the system immediately resolves that value into an IP address. It also stores it in the nas_ip_address field of the NAS File System [cmdb_ci_nas_file_system] table.

    Discovery creates the following relationships for storage CIs running on Network Attached Storage (NAS). These relationships are the same between Linux and Windows operating system hosts.
