OceanProtect has three main highlights that make it a leading backup storage product in the industry. First, it offers fast backup and recovery with E2E acceleration, high bandwidth, and instant access technologies, delivering up to 155 TB/h backup bandwidth and 172 TB/h recovery bandwidth1. Second, it provides efficient data reduction with multi-layer deduplication, feature-based reduction, and E2E data reduction technologies, achieving a premium datareduction ratio of up to 72:11. Third, it ensures high reliability with cyber resilience, system resilience, and lifecycle management features. OceanProtect adopts the industry’s exclusive active-active dual-controller architecture that guarantees uninterrupted backup services even in the event of a controller failure1.

OceanStor Pacific is a distributed storage system that is designed for massive data applications. It supports multiple protocols, such as NFS, CIFS, S3, and HDFS, and provides high performance, scalability, reliability, and efficiency for unstructured data storage. OceanStor Pacific can handle data volumes ranging from hundreds of TBs to EBs, and can meet the storage requirements of various scenarios, such as big data analytics, backup and archiving, video surveillance, and media production.

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 .

Archive storage is a type of data storage that is used to store and preserve data that is rarely accessed, but may be needed for legal, compliance, or historical purposes. Archive storage typically has lower performance and higher capacity than primary storage, and often uses compression, deduplication, and encryption to reduce costs and enhance security. Archive storage can be located on-premises or in the cloud

OceanStor Dorado high-end storage can provide 7-nines system reliability, which means the system downtime is less than 3 seconds per year. This is achieved by using the SmartMatrix architecture, which ensures no single point of failure and supports cross-engine active-active mode.

E2E NVMe capability is the most important technology to help OceanStor Dorado reach the fastest file operation speed that the industry has ever seen. E2E NVMe means that NVMe is used throughout the entire data path, from the front-end interface to the back-end SSDs. This eliminates the performance bottleneck caused by traditional SCSI protocols and improves the I/O efficiency and latency significantly. E2E NVMe enables OceanStor Dorado to deliver up to 20 million IOPS and 0.1 ms latency for file operations. Reference: [OceanStor Dorado All-Flash Storage Product Brochure]

OceanStor Dorado can support both block and file services in one box, which means it can host all kinds of applications such as databases, file servers, virtual machines, containers, etc., without requiring separate devices or gateways. OceanStor Dorado supports mainstream protocols such as iSCSI, FC, NFS, and SMB, and provides ultra-high performance, low latency, and high reliability for data storage.

RAID-TP is not a technology used by OceanProtect to accelerate backup and recovery performance. RAID-TP is a technology used by OceanStor Dorado to improve data reliability and availability. OceanProtect uses other technologies to speed up backup and recovery, such as front-end network optimization, CPU computing optimization, and back-end network optimization.

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 .

DME Storage is the software developed by Huawei that provides your data center with centralized management and O&M for storage devices. It covers four phases of the device lifecycle (planning, provisioning, maintenance, and optimization), and improves the automation level and problem resolution rate. DME Storage supports Huawei’s full series of centralized storage, Huawei distributed storage, and several mainstream third-party storage systems. Reference: DME Storage 1.0.0 User Guide

OceanProtect has high data reduction ratio because it uses advanced deduplication and compression technologies to eliminate redundant data and save storage space. This reduces the backup storage space required and lowers the total cost of ownership (TCO) for customers. Reference: [OceanProtect Backup Storage Product Brochure]

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

The advantages of Huawei OceanProtect over traditional backup storage are rapid backup, rapid recovery, high reliability, and efficient reduction. OceanProtect can provide fast backup and recovery performance by using front-end network optimization, CPU computing optimization, back-end network optimization, and intelligent scheduling technologies. OceanProtect can also ensure high reliability by using RAID-TP technology that can tolerate the simultaneous failures of three disks in a RAID group. Moreover, OceanProtect can achieve high data reduction ratio by using deduplication and compression technologies that can reduce the backup data size by up to 90%.
