The Challenge of Mass Unstructured Data.
According to Huawei's Intelligent World 2030 report, 1 YB — yottabyte — of data will be generated annually worldwide by 2030, representing a 20-fold increase over 2022. That's equivalent to the capacity of four trillion 256 GB mobile phones.
Undoubtedly, we are entering a new era, one where more than 80% of data is unstructured. Here, evolving big data and Artificial Intelligence (AI) technologies have paved the way for extracting value from this unstructured data and it's time for enterprises to consider how to properly back up and archive it, including long-term retention in line with regulatory compliance.
Insufficient capacity for mass data
Traditional scale-up storage arrays cannot keep up with exponential data growth. Unstructured data requires long-term retention in accordance with regulatory compliance. Mass data storage often leads to soaring Information Technology (IT) costs.Data Silos for Different Backup and Archiving Applications
Different applications use different access protocols, leading to siloed deployment that restricts data mobility. Applications are characterized by different read-write performance models, causing mutual interference that negatively impacts the user experience.Reliability for Valuable Unstructured Data
Unstructured data is now a key digital asset that requires higher levels of protection and reliability. While nearby data access is required to ensure the user experience, cross-site data access also needs to be more reliable.Object Storage Is a New Way to Store Mass Data
Easier Access
Object storage allows different devices to access data, from anywhere and at any time. Unlike Network-Attached Storage (NAS), which involves complex protocols and network interactions, object storage reads and writes data via RESTful Application Programming Interfaces (APIs), eliminating cyber security risks and allowing for data transmission over public networks. Thanks to the development of the Internet, a wider range of devices support S3.
Faster Read
With a flat data structure, object storage delivers higher read performance when handling mass data. In traditional file storage, data is stored as files in folders and organized in a tree structure, similar to putting items in different drawers of different cabinets in different rooms. In contrast, object storage directly reads files through URLs, akin to putting all items in one large drawer and simply opening it to directly select items. Tests show that, with 100 billion files, object storage delivers 10 ms read speeds, compared to the seconds that file storage needs.
Quicker Search
Unlike traditional file storage , user-defined metadata is a part of the object itself, meaning that users can customize tags for each object. This makes it easier to search mass data for objects with the same tag. To implement a similar function, traditional file storage needs an additional, separate tagging and indexing system.
Architecture
Running on a distributed object storage foundation, Huawei OceanStor Pacific provides End to End (E2E) data infrastructure services for mass unstructured data, such as videos and images, covering production, backup, and archiving. It supports hybrid workloads and offers unique features like multi-protocol interworking, multiple active data centers, deduplication, and compression.
