Relocating SQL Server databases due to data center moves and infrastructure changes can be challenging. If databases are large, establishing, testing, and monitoring a process to move data reliably can be time consuming. SQL Server contains functionality to migrate databases, but often there is data that is required by the application that resides outside of the database, such as configuration files, images, and so on. A separate process is then needed to transfer this data, adding to the complexity. After the data is transferred, typically an outage needs to be scheduled to perform final synchronization tasks and a cutover of the application from the old location to the new location.
Metro node expands the data mobility features of PowerStore and complements the functionality of SQL Server by allowing data to be moved non-disruptively between any supported storage devices. This allows data mobility not only between supported Dell arrays, but between other vendor arrays. Some common uses include data center consolidation, hardware maintenance, moving data and applications over distance, and load balancing between dissimilar storage.
Because metro node is a separate appliance, it can perform mobility tasks at enterprise scale. Metro node supports up to 25 Local and 25 Metro concurrent migration sessions. It also supports queuing additional migration sessions for performing large-scale migration tasks.
