Backup storage is a type of data storage that is used to create copies of data that can be restored in case of data loss, corruption, or disaster. Backup storage typically has high performance and reliability, and often uses incremental or differential methods to reduce the amount of data that needs to be backed up.Backup storage can be located on-premises or in the cloud

Huawei high-end flash storage, such as OceanStor Dorado 8000/18000, supports a fully-interconnected active-active SmartMatrix 3.0 architecture that ensures the stable running of services, even if seven out of eight controllers, or one out of two controller enclosures, fail.This feature sets unprecedented standards for industry reliability

All-flash storage is not recommended to use for video surveillance system because video surveillance data is usually large in size, sequential in nature, and infrequently accessed. All-flash storage is more suitable for applications that require high performance, low latency, and random access.Video surveillance system can benefit from using hybrid flash storage or hard disk drives that offer more capacity and lower cost

All-flash storage can contribute to carbon neutrality by reducing the energy consumption and carbon footprint of data centers. Compared with mechanical disks, fewer SSDs can provide the same or higher performance and capacity, while saving more energy.According to a report by DEKRA9, taking a data center with 1000 disks as an example, replacing mechanical disks with SSDs reduces power consumption by 2.4 times and carbon emissions by 2.3 times per year1

OceanStor Dorado 8000 and 18000 are the high-end all-flash storage systems in the OceanStor Dorado series. They are designed for mission-critical workloads, providing high performance, reliability, and intelligence. They can support up to 32 controllers, 32 TB cache, and 6400 enterprise-class SSDs.

OceanStor Dorado can support multiple sales scenarios, such as databases, virtualization, and High-Performance Data Analytics (HPDA). OceanStor Dorado can provide low latency, high throughput, and high IOPS for database applications, such as Oracle, SAP HANA, and MySQL. OceanStor Dorado can also optimize the performance and efficiency of virtualization environments, such as VMware, Hyper-V, and OpenStack. Moreover, OceanStor Dorado can accelerate the data processing and analysis of HPDA applications, such as EDA, AI, and big data.

OceanStor Dorado can support multiple types of 3DC solution, which is the core of the Geo-Redundant Solution that ensures service continuity and data reliability in case of disasters. The 3DC solution consists of a production center, an intra-city DR center, and a remote DR center. The supported 3DC topologies are parallel, serial, and star. In parallel topology, both the production center and the intra-city DR center form remote replication relationships with the remote DR center. In serial topology, the production center forms a remote replication relationship with the intra-city DR center, which in turn forms another remote replication relationship with the remote DR center. In star topology, the production center forms a HyperMetro relationship with the intra-city DR center, and both of them form remote replication relationships with the remote DR center.

Dorado can provide secure snapshot as an anti-ransomware function. Secure snapshot is a feature that allows users to create read-only copies of data at a specific point in time. Secure snapshots are protected from deletion or modification by ransomware or unauthorized users. Secure snapshots can also be used to quickly restore data to a previous state in case of ransomware attacks .

In Huawei E2E anti-ransomware solution from production storage, to backup storage and to DR storage, the products are OceanStor Dorado, OceanStor Pacific, and OceanProtect. OceanStor Dorado is the production storage that provides high performance and reliability for critical applications. OceanStor Pacific is the backup storage that provides efficient data reduction and protection for large-scale data. OceanProtect is the DR storage that provides fast backup and recovery for disaster scenarios .
