NEC Storage DynamicDataReplication creates replication of business volumes defined per logical disk and separates the replicated volumes at any time. This product provides fundamental functions to support 24*7 operations and the extension of online business hours.
For example, it supports efficient processing of an ever-increasing amount of data and enables online business concurrent with batch and backup operations after business hours.
- A replicated volume can be separated at any time to be used for a different purpose.
- For reconnection, the update differential management function enables quick resynchronization.
NEC Storage DynamicDataReplication Express (DDR Express) provides functions for data replication and snapshot within the same disk array, using NEC Storage Manager Command. DDR Express allows backups that are achieved by stopping application servers at a low cost.
