Preparing for the Configuration
To successfully configure the HyperReplication feature, make preparations in advance, for example, obtaining the HyperReplication license, setting device information, and selecting replication ports for data transmission.
Activating the License
Before configuring HyperReplication, import and activate its license file to enable HyperReplication to take effect.
- If you do not have its license, contact technical support to obtain the license.
- If you have obtained its license, follow instructions in Managing License File in the Online Help to import the license file to the primary storage system and secondary storage system respectively and activate them.
Setting Device Information
To distinguish between primary and secondary storage devices, you need to set the device information on both storage devices, including device names and locations before configuring the HyperReplication feature. Log in to DeviceManager and choose Settings > Basic Information > Device Time to set device information.
Selecting Replication Ports
HyperReplication supports data transmission through Fibre Channel ports or Ethernet replication ports.
- Fibre Channel port
Fibre Channel ports feature high transmission rate and low transmission latency. However, Fibre Channel ports use multi-mode optical fibers as transmission media. Multi-mode optical fibers support only a short transmission distance. Therefore, HyperReplication that uses Fibre Channel ports is suitable for short-distance backup and DR.
- Ethernet replication port
Typically, Ethernet replication ports are inferior to Fibre Channel ports in terms of transmission rate and latency. However, Ethernet ports carry data by using the IP protocol. Therefore, data can be backed up to the secondary storage system through the Internet or dedicated cables, achieving remote backup and DR across cities, provinces, and even countries.
Understanding the advantages and disadvantages of data transmission based on Fibre Channel ports and those of data transmission based on Ethernet ports helps you select replication ports that best meet service requirements. After you select a front-end port type, the corresponding link type is also selected by default. In an actual networking scenario, you must also consider factors such as the bandwidth, latency, network quality, and security to ensure link efficiency and stability during data transmission.
