## Creating and Assigning SME Roles and SME Users

The SME feature provides two primary roles: SME Administrator and the SME Recovery Officer. The SME Administrator role also includes the SME Storage Administrator and SME KMC Administrator roles. By default, SME assigns both the SME Administrator and the SME Recovery Officer to the same user. This assignment works well for small scale deployments of SME.

Note The DCNM-SAN user credentials must be the same as the switch user.

Table 1-4 shows a description of the SME roles and the number of users that should be considered for each role.

Note SME is configured from the DCNM-SAN Web Client. Internally, the actual switch operations are executed on behalf of the user that is logged into the Web Client and not the user monitoring the fabrics. Therefore, in a multifabric configuration the SME administrators must have the same username and password across all the fabrics to perform the SME operations.
