What are the advantages of cloud storage technology?

Compared to the traditional IPSAN approach, the advantages of cloud storage are obvious.

1. Simple maintenance

Cloud storage provides a cluster management mode. Users only need to log in to an IP address of the cloud storage system to view all storage device status, corresponding disk status, and overall storage usage. The system also provides alarm notification and log records for different abnormalities and faults in a timely manner, which greatly simplifies the administrator's maintenance and management of the storage system.

2. Safe to use

The cloud storage system adopts a distributed discrete storage strategy based on erasure code or multiple copies. The erasure code can allow the system to have more than one hard disk or even multiple storage device nodes, and will not cause data loss. In addition, the hard disk is recovered after the hard disk is damaged. Data is reconstructed simultaneously by multiple storage nodes in an idle space, which is much faster than the traditional disk-based Raid, and the reconstruction speed can be less than 1 hour. Multiple copy mode stores multiple copies in different nodes in the system. Generally, 3 copies start, and any two copies of data are lost, and the data is still not lost.

3. Dynamic expansion and expansion, more convenient expansion

In traditional storage, the business system directly deals with each storage device. Each time it is expanded, it must identify and mount new storage devices, and migrate the original data, resulting in long-term business interruption. The cloud storage adopts the storage virtualization technology. The service system only senses the change of the overall capacity and does not care about the specific device. After the expansion, the original data is automatically reorganized and balanced in the new storage space, and the service is not affected.

4. Data sharing is barrier-free

The traditional storage interface is closed. A storage system only connects a set of services. Each service such as video surveillance, intelligent analysis, and image detection must establish its own storage system. The data sharing efficiency between each other is very low. The cloud storage provides a unified storage space and a namespace. Different business systems have consistent access to the storage system. These data can be directly read through a unified named path under the control of the authority, thereby improving the relationship between different business systems. The ability to share data information.
