Technical Advantages

ZettaStor DBS is the first product developed by Pengyun Network. Version 1.0 was officially released in 2015 and mainly adopted by cloud computing companies.

The first commercial version of DBS is developed according to the standard requirements of telecom operators, and has passed the tests of China's three major telecom operators for telecom equipment applications. In recent years, DBS has been polished for the financial industry, its stability and reliability has been further strengthened and has been operating stably in key business scenarios for 4 years.

ZettaStor DBS has completed the leap from telecom-grade to financial-grade. It is a distributed storage product with a high starting point and high requirements, which can meet the new and changing needs of the market.

• [x] Decentralized Architecture: A symmetric distributed architecture based on the decentralized blockchain network, eliminates traditional limitations and disadvantages on system scale, I/O performance, stability and reliability.
• [x] Large-scale Node Deployment: Stable high-performance is constantly maintained at optimal conditions, with the deployment of tens of thousands of nodes. The product's capacity and performance scale linearly with more storage nodes.
• [x] Sub-millisecond Latency: Minimized I/O processing path by directly reading/writing to disk, using an optimized network data path. It is capable of achieving sub-millisecond latencies with magnetic storage devices as primary storage configuration.
• [x] Recovery-in-place: When a hard disk or node failure occurs, a healthy one can immediately take over. The fault recovery time is less than 1 second, and there will be no impact on I/O performance.
• [x] Secure and Controllable: Complete intellectual property ownership with independent research-and-development, compatible with China-made hardware, operating systems and localized storage solutions.
