About Cisco MDS DMM

Cisco MDS Data Mobility Manger (DMM) is an intelligent software application for achieving data migrations. DMM runs on the Storage Services Module (SSM) of an MDS switch and operates across the SAN fabric.

Cisco MDS DMM offers capabilities and features that simplify data migration and minimize disruptions and reconfigurations. For example, the SSM can be located anywhere in the fabric. No reconfiguration is required for the server, the existing storage, or the SAN fabric. Cisco MDS DMM uses resources on the SSM card to perform the migration, so it adds no processing overhead on the application servers

Cisco MDS DMM supports online migration, allowing applications to continue to access the existing storage devices. The SSM coordinates all server access to the storage and runs the data migration. However, this activity is transparent to the server, which continues to have full access to the data.

Cisco MDS DMM supports data migration at the server or storage device level of granularity. Server level migration involves migrating the storage data used by the specified server. Storage device level migration involves migrating all storage data from the specified storage device.
