6. U.S. Patent No. 9,495,113: Systems, devices, apparatus, and methods for identifying stored data by a device located in a path between virtual Fibre channel switches and performing a data management service – Issued November 15, 2016
U.S. Patent No. 9,495,113 is the 6th patent granted to Cirrus Data Solutions Inc. It covers the logical insertion technique for both host side and storage side configurations. With the logical insertion technique, storage links can be transparently inserted using switch commands either manually, or via the Cirrus Migrate On-Premises (CMO) insertion wizard. The current wizard supports most popular switch models, including Brocade and Cisco. Using the technique described in this patent, CMO appliances are inserted into active data paths without touching any physical cables in the storage environment. CMO appliances are simply connected into the production switches and logically inserted into data paths in a completely transparent manner, with zero disruption to the data I/O. Selected data volumes can then be migrated with minimal or no impact to production. This insertion technique also provides the most flexibility and scalability for planning and execution of mass data migration. In large environments, hosts can be selectively migrated, leaving the rest of the storage environment untouched an unaffected by migration.
