WBEM na-agba n'elu protocol HTTP. Site na WBEM ị nwere ike ịrụ ọrụ ọ bụghị naanị na sistemụ nchekwa, kamakwa na HBA, switches na ọba akwụkwọ teepu.

Dị ka SMI Architecture и Kpebie akụrụngwa, akụkụ bụ isi nke mmejuputa SMI bụ sava WBEM, nke na-ahazi arịrịọ CIM-XML sitere n'aka ndị ahịa WBEM (n'ọnọdụ anyị, site na nleba anya scripts):

Nke a bụ njikọ mebere, ebe CIM-XML/WBEM na-agba ọsọ n'elu HTTP, ezigbo njikọ na-eme mgbe a na-akpọ usoro na ihe atụ nke klaasị WBEMConnection. Dabere na IBM System Storage SAN Volume Controller na Storwize V7000 Best Practices and Performance Guidelines (Ihe atụ C-8, ibe 412), anyị ga-eji "mgbọrọgwụ / ibm" dị ka CIM aha ohere maka IBM Storwize usoro nchekwa.
