CIM Discovery requirements These are the requirements for storage discovery via SMI-S and CIM. A CIM server using SMI-S 1.5 or later. NAS and SAN systems from major vendors such as EMC, Hitachi, HP, and NetApp. SAN storage devices must use FC. FC switches from major vendors such as Brocade and Cisco. The CIM credentials must be available for SMI-S configuration. The CIM credentials can be different than the credentials for the system hosting the CIM server. Note: Because the SMI-S Provider caches storage device information, the Discovery query to the provider does not affect storage device performance.
