Orient securities is a comprehensive securities company approved by China Securities Regulatory Commission. It is a listed securities financial holding group that provides comprehensive financial services such as securities, futures, asset management, wealth management, investment banking, investment consulting and securities research. At the same time, adhering to the enterprise spirit of "unity, enterprising, pragmatic and efficient", we are committed to "becoming a modern investment bank with first-class core competitiveness in the industry and providing customers with comprehensive financial services".
Orient securities information architecture uses software definition and flexible modular design to reshape the business system, and at the same time, three lines go hand in hand: private cloud, agile development (including containers) and big data to support business development. Remote disaster tolerance and data backup are realized by using multi-data center and multi-cluster deployment, and intelligent operation and maintenance and data visualization are realized by combining system monitoring and intelligent operation and maintenance.
Business-driven infrastructure innovation and upgrading
From 20 14, orient securities began to use hyper-converged architecture. From well-known foreign manufacturers to domestic manufacturers, orient securities is also in the forefront of the industry in terms of the number of hyper-converged nodes. With the deepening of hyper-convergence, orient securities not only needs to realize the basic functions of resources, but also needs to provide higher performance and diversified data redundancy mechanisms for services in terms of application data and storage mechanisms.
Huayun Data Anchao OS has carried out several rounds of stability and reliability tests in orient securities, providing dynamic allocation of basic resources of virtual machines. Data storage supports all-flash and hybrid flash disk configuration, and has realized various advanced functions such as customized storage block size (4K 32K), customized data copy number and rack awareness. Application performance and data protection have been improved to a certain extent, and the whole solution architecture has been unanimously recognized by customers.
Building Hyperconverged Architecture to Support Business Development
Huayun Data adopts the hyper-converged architecture built by Anchao OS, provides computing storage supply and management capabilities based on 2U converged servers, is deployed in clusters, and is centrally managed by using the existing management platform. Anchao OS is deployed in the virtualization management program, which can realize the concentration of physical storage resources in each server and form a unified storage resource pool for management. At the same time, Amway OS provides storage pools to realize virtual machine-centric IT infrastructure management, which fills the gap between storage infrastructure and virtualization platform and brings efficiency, flexibility and stability to the architecture.
Architecture advantage
Seven fault-tolerant mechanisms for data protection
Huayun Data Anchao OS adopts a fully fault-tolerant architecture design, providing an end-to-end fault-tolerant and disaster-tolerant solution. Through data verification, network fault tolerance, cache fault tolerance, data fault tolerance, node fault tolerance, rack fault tolerance and cluster fault tolerance, the risk of data fault tolerance and data loss is solved, and multiple protection of data is realized.
Set the block size of the application type.
The size of the block or the size of the memory page determines the minimum space allocation unit of the virtual machine on the hyper-converged data storage. The default page size of hyper-converged data storage is usually 4K. During the configuration process, Chao OS provides an option to configure the page size of hyper-converged cluster datastore and the default page size of virtual machine disk (VMDK) deployed to datastore.
Data compression algorithm and replication
The platform provides three compression algorithms for the virtual machine and two data copies. Lz4 is usually used to realize data compression. You can choose gzip_high or gzip_opt to obtain a higher compression ratio to improve storage utilization. The mixed setting of 2 copies and 3 copies of disks provides a more diversified storage mechanism for the application system;
Virtualization configuration strategy
The striping strategy of Amway OS and the configuration of virtual disks related to virtual machines will bring performance improvement. Configuring multiple virtual disks for each virtual machine will improve the utilization rate of each physical disk in a hyper-converged cluster, thus improving the overall performance of the cluster. In addition, Amway OS Hyperconvergence is optimized in the Vsphere environment, and a data virtual disk connected to a semi-virtual SCSI controller is realized.
Improving IT capabilities will bring multiple benefits.
With its strong product self-research ability and accumulated practical experience in the financial field, Huayun Data fully meets the infrastructure requirements of agile business in orient securities by using Amway OS in this project, providing all-round one-stop and full-life cycle services, and ensuring the continuity of the system with 7x24+360 technical support.
Huayun Data has helped orient securities to improve its IT capabilities and realize business transformation, which has brought great benefits and value. At the same time, with the help of orient securities's existing cloud management platform, "one cloud with multiple stacks, green and low carbon" has been realized, which responds to the development principles of "digital drive, wisdom for the people, green and low carbon, fairness and inclusiveness" in the Financial Technology Development Plan (2022-2025).
As a typical representative of many financial technology industries, orient securities has been at the forefront of digital transformation. IT is also a strong proof that Huayun Data helped orient securities build a cloud platform and upgrade its IT infrastructure. For orient securities, Huayun Data not only provides the core strength for the digital transformation of its business, but also promotes the digital transformation process of the securities industry and leads the development of financial technology in the industry.
Financial digitalization has changed from a technological revolution to a strategic engine leading high-quality business development and systematic services. As a solid force behind the digital transformation of finance, Huayun Data will continue to explore and innovate in the future, providing products and solutions that are safe, compliant, stable, reliable, quick to realize, extremely easy to use and easy to expand for the financial sector and the securities industry, and will continue to help orient securities and other financial users lead the wave of digital transformation, maintain the competitiveness and growth vitality of enterprises, and expand more economic value and social benefits.
