Cisco Data Mobility Manager For MDS 9250i - Subscription License (6 Months) - ESD - L-M9250IDMMT6M=

• Exceptional flexibility and scalability
  Cisco MDS DMM does not require rewiring or reconfiguration of existing SANs, thereby enabling online migration of block data with minimal downtime enhanced scalability can be achieved by transparently adding modules to the switching fabric.
• Online data migration
  The Cisco MDS DMM is designed to provide transparent online data migration. The existing storage will be available to the server applications when the card performs the data migration. During migration, the read operations issued from the server are serviced from the existing storage, and the write operations are mirrored across both existing storage.
• Deployment flexibility
  The Cisco MDS DMM is designed to perform data migration without any additional layer of virtualization between the server and the storage. The virtualization-free design of the Cisco MDS DMM increases deployment flexibility with a nondisruptive SAN rollout that does require SAN rewiring or reconfiguration.
• High performance
  The Cisco MDS DMM minimizes server CPU utilization during data migration. Utilization of server CPU cycles for data migration reduces application performance. For example, in server-based migrations using a volume manager, the server I/O bandwidth is utilized to move data from existing to a storage with the involvement of the server CPU.
• Unmatched features
  In addition to its basic data migration capability, the Cisco MDS DMM offers several features of interest to a SAN administrator. One feature is the capability to control the rate of migration so that the administrative traffic tied to the migration can be adjusted according as its effect on the applications and targets. Other features include the capability to securely erase the data from the existing target logical unit numbers (LUNs) and a verification option that performs a block-by-block comparison so the administrator can check the accuracy of the migration.
• Comprehensive security and availability
  RBAC allows the SAN administration functions to be partitioned by user and role to help ensure secure operation and configuration of the SAN. Additionally, when director-class switches are used, the Cisco MDS DMM automatically inherits the high availability featuresthat are intrinsic to this class of switches.
• VSAN support
  The Cisco MDS DMM minimizes disruption of the existing production environment. The Cisco MDS DMM is an online process and does not require any rewiring or reconfiguration of zones or VSANs.
• Simplified management
  The Cisco MDS DMM can be enabled and disabled using simple software controls issued from a centralized management console. The Cisco MDS DMM feature comes with its own configuration wizard that guides the user through a set of simple-to-understand steps, with drop-down menus available to facilitate the selection process. The wizard was designed with ease of use as its primary objective, a focus apparent to even first-time users. The Cisco MDS DMM also includes command-line interface (CLI) commands that advanced users can use to create scripts to configure and monitor their migration tasks.

The Cisco MDS Data Mobility Manager (DMM) is a storage area network (SAN) fabric-based software application that enables movement of blocks of data from a source device to a destination device. The Cisco MDS DMM is implemented on the storage services module (SSM) line card.
The Cisco MDS DMM feature is enabled through a separate end-user software license. The Cisco MDS DMM feature can be introduced transparently without the need to reconfigure or rewire the existing SAN infrastructure, and it can enabled or disabled using software control from the configuration GUI. No configuration is required on the host as the host initiators do not know that the Cisco MDS DMM service is inserted. Similarly, no reconfiguration is needed on the target as the target also does not know that the Cisco MDS DMM service is inserted in the SAN. There is also no need for any SANbased configuration such as zoning or virtual SAN (VSAN) configuration.
This transparent insertion of service makes moving data from an existing storage device to a storage device during upgrades, consolidation, or removal of existing storage devices easy. The Cisco MDS DMM is competitively priced and offers enterprise-class capabilities. The Cisco MDS DMM is a nonintrusive, online data migration solution that requires no reconfiguration of existing SANs and is centrally managed across heterogeneous storage devices.
