Brief Introduction to Storage Discovery

Overview

The Storage discovery enables you to discover storage structures and connections between storage systems and remote servers.

• Storage structures

  Universal Discovery discovers both physical and logic relationships between components in storage systems. Generally, the components include storage array, storage pool, Logical Unit Number (LUN), storage processor, logical volume, physical volume, fibre channel port, Small Computer System Interface (SCSI), Internet Small Computer System Interface (iSCSI), and file export.

• Connections between storage systems and remote servers

  Universal Discovery discovers the following three types of connections: Network File System (NFS), iSCSI, and Storage Area Networks (SAN).

Supported Protocols

The Storage discovery uses the following protocols:

• NetApp Protocol
• CIM Protocol

• SNMP Protocol

  Note Only limited CIs can be discovered via SNMP Protocol because it is not a standard protocol for storage devices.

Supported Discoveries

The Storage discovery includes the following discoveries:

• NetApp Filer discovery

  The storage discovery via the NetApp protocol is the NetApp Filer discovery.

  This discovery is based on NetApp Data ONTAP API (ONTAPI) that can be used to access and manage the storage system.

  The discovery jobs are NetApp Filer Connection by WebServices and NetApp Filer by WebServices.

  For details, see NetApp Filer Discovery.

• SMI-S discovery

  The storage discovery via the CIM protocol is the SMI-S discovery.

  This discovery is based on Storage Management Initiative Specification (SMI-S).

  The SMI-S discovery supports the following storage device brands:

  • Brocade
  • EMC
  • Hitachi
  • HPE
  • Huawei
  • IBM
  • NetApp

  The discovery jobs are Storage Devices Connection by CIM and Storage Devices Topology by CIM.

  For details, see SMI-S Discovery.

• Storage Devices by SNMP discovery

  The storage discovery via the SNMP protocol is the Storage Devices by SNMP discovery.

  The Storage Devices by SNMP discovery supports the following devices:

  • EMC Isilon Filers
  • EMC Data Domain storage systems

  The discovery job is Storage Devices Topology by SNMP.

  For details, see Storage Devices by SNMP Discovery.
