Other tools, such as backup and restore products, data mirroring products, data replication products, or FC/iSCSI storage routers, can be re-positioned as data migration tools. However, most of them lack features that are specific to this function (for example, a DoD-strength secure erasure function to ensure the old storage data is cleanly wiped out), or their lack of total transparency requires host-side drivers or other agents to be deployed.
The insertion of the DMS appliance into the existing production system and the execution of the entire migration project is performed with minimal risk, and without downtime.
This means IT managers or service providers can avoid all the pain-points associated with the certification of host drivers, changing of multi-path software, or scheduling downtime for the migration. The enormous amount of work and potential down-time avoided translates to a significant amount of cost savings and greatly improves ROI.
