Overview
This section describes the background, definition, and benefits of the HyperReplication feature.
Background
As digitalization advances in various industries, data has become critical to the operation of enterprises, and customers impose increasingly demanding requirements on stability of storage systems. Although some storage devices offer extremely high stability, they fail to prevent irrecoverable damage to production systems upon natural disasters. To ensure continuity, recoverability, and high reliability of service data, remote DR solutions emerge. The remote replication technology is one of the key technologies used in remote DR solutions.
Definition
HyperReplication is a core technology for remote DR and backup of data.
It supports the following replication modes:
- Synchronous remote replication
In this mode, data is synchronized between two storage systems in real time to achieve full protection for data consistency, minimizing data loss in the event of a disaster.
- Asynchronous remote replication
In this mode, data is synchronized between two storage systems periodically to minimize service performance deterioration caused by the latency of long-distance data transmission.
Benefits
Table 1-1 lists the benefits of the HyperReplication feature.
Function |
Purpose |
Benefit |
|---|---|---|
Remote backup and recovery |
To recover service data using backup data in a remote storage system after the service data becomes unusable. |
This function prevents damage caused by data loss in the case that data at the primary site becomes unusable. |
Continuous support for services |
To quickly switch service data from the primary site to the secondary site, protecting service continuity. |
This function prevents damage caused by a service interruption upon a failure at the primary site. |
DR |
To recover data at the primary site using backup data at the secondary site in the event of a disaster. |
This function prevents the damage caused by service data loss or a long recovery duration upon a disaster. |
Note 1: A primary site is a production center that includes the primary storage system, application servers, and links. Note 2: A secondary site is a backup center that includes the secondary storage system, application servers, and links. Note 3: Unless otherwise specified, hosts mentioned in this document refer to application servers. |
