Building an IT system where a diverse range of business
activities are carried out requires the efficient use of data and a
system with high availability. Storage Control Software provides
the basic system functions to ensure that the system is highly
available and operable, with a data protection function with no
influence on online operations, a disaster recovery function,
autonomous resource management, and the efficient use of
resources.
Replication
Storage Control Software provides functions for protecting data
and improving the operability of data without affecting online
operations by duplicating volumes in the storage system.
Replication
• NEC Storage DynamicDataReplication
• NEC Storage RemoteDataReplication
These provide replication functions for systems that require high performance and high reliability.
• NEC Storage DynamicSnapVolume
Provides a replication function for cost-performance-oriented systems, with the ability to create snapshots holding the differences in updated data only.
