NEC Storage DynamicDataReplication
Basic information
|
||
|
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. |

Functions |
||
|
The following is a description of the main functions of NEC Storage DynamicDataReplication. |
||
|
Restoration protecting replicated volumes |
||
|
When a replicated volume is copied to the master volume for restoration, selection of whether the replicated volume reflects access from business servers to the master volume or not is possible. |
||
|
Immediate separation of replicated volumes |
||
|
Even before the copy of a master volume is completed, the replicated volume can be separated and used as the copy of the master volume. |
||
|
Application examples |
||
|
Backup concurrent with online business |
||
|
Online data can be replicated easily. This replicated data can be used as a backup. Since replicated data is created using an NEC Storage disk array system's resource, the operation does not put any load on servers or influence online business. Data can be extracted from a replicated database and saved to a tape without interrupting on-going business operations. Online response during data saving is perfectly safe. |
||
 |
||
|
Search operation concurrent with online business |
||
|
By retaining the data for search operation independently in a replicated volume, business operation and search operation can be performed without influencing each other. With this configuration, disk access competition and deadlocks are eliminated. |
||
|
Concurrent batch processing |
||
|
Concurrent batch processing using a replicated volume significantly reduces processing time. |
||
|
Building an application evaluation environment |
||
|
An application evaluation environment can be configured easily by using replicated volumes. Repeated tests with the same data are possible by using a restored copy without reflecting master volume update to the replicated volume. |
