Storage Discovery via SMI-S and CIM Discovery identifies and classifies information about storage devices. Discovery can explore storage devices that contain a Storage Management Initiative Specification (SMI-S) provider that is a specialized Common Information Model (CIM) server. To see the current list of vendors and products conforming to SMI-S as tested by SNIA, see the SNIA website. Other types of storage, such as storage that is attached via a host, VM storage that is available on VMware ESX servers, and storage for Kernel VM (KVM), use a separate set of probes and sensors. Discovery collects information about storage area networks (SAN) and network-attached storage (NAS) from specialized devices, such as storage arrays and Fibre Channel (FC) switches. Discovery collects and creates CIs in the CMDB for the following information items: Array disks, pools, and volumes Fibre Channel HBAs, ports, and controllers FC exports Fabrics, including endpoints, zoning, and switches Dependencies between storage sub-components Data collected Discovery uses the following tables and probes to gather information about storage devices that are managed by a SMI-S provider.

By default, Discoveryuses CIM probes to explore storage systems as well as to get the serial numbers of ESX servers.CIM Discovery requirementsThese are the requirements for storage discovery via SMI-S and CIM.SMI-S and CIM probes and sensorsThese probes and sensors are used for SMI-S and CIM Discovery.How CIM Discovery worksHow CIM Discovery WorksConfigure Discovery for a standalone storage deviceUse this procedure for configuring a standalone storage device with the required SMI-S Provider for Discovery.Discovery storage schemaThis diagram displays the disk hierarchical schema for storage Discovery.Data collected by Discovery on storage devicesDiscovery identifies and classifies information about storage devices.
