Introduction 51IntroductionThe Dell PowerVault Modular Disk (MD) storage arrays provide an industrystandard application programming interface (API) called the StorageManagement Initiative Specification (SMI-S). This interface enables thirdparty SMI-S client applications to manage MD storage arrays in a multi-vendorstorage area network (SAN) environment.SMI-enabled management applications are known as CIM clients. To allowclients to manage a storage device, an SMI-S Provider (also called SMI-SAgent or CIM Agent) is required. SMI-S Providers can be implemented as:• A proxy interface that translates the existing API of a device to an SMI-Scompliant interface. This implementation is the quickest path to SMI-Scompliance, but a proxy provider and a Common Information ModelObject Manager (CIMOM) must be installed on a server. A CIMOM is aCIM/WBEM infrastructure that receives, validates, and authenticatesCIM requests from the client application. The CIMOM directs therequests to the appropriate device provider.• A native feature of the storage device API. This implementation issometimes referred to as an embedded agent.Dell MD SMI-S Provider is implemented as a proxy interface. The DellSMI-S Provider, referred to as SMI-S Provider, runs on a server on the storagenetwork. OpenPegasus CIMOM is installed during the installation of thisSMI-S Provider.The SMI-S Provider provides the SMI-S interface to the Dell PowerVaultModular Disk storage array family. The provider uses the proxy CIM Agentmodel and is supported on Microsoft Windows and Linux platforms only.
