About SME
A Cisco KMC is configured only in the primary data center and DCNM-SAN servers are installed in all
the data centers to manage the local fabrics and provision SME. The SME provisioning is performed in
each of the data centers and the tape devices and backup groups in each of the data centers are managed
independently.
Figure 1-2
Multisite Setup in Cisco KMC
In the case of multisite deployments when the Cisco KMC is separated from DCNM-SAN, fabric
discovery is not required on the Cisco KMC installation. The clusters that have connection to the Cisco
KMC will be online and the clusters that are not connected, but are not deactivated, appear as offline.
The SME clusters that are deleted from the fabric appear as deactivated.
The high availability Cisco KMC server consists of a primary server and a secondary server. When the
primary server is unavailable, the cluster connects to the secondary server and fails over to the primary
server once the primary server is available. The high availability KMC will be available after you
configure the high availability settings in DCNM-SAN Web Client.
Clustering
Cluster technology provides reliability and availability, automated load balancing, failover capabilities,
and a single point of management.
