Jinzheng Securities Company is facing the same problem in the server switching project of the new platform of the intelligent trading platform of Jinzheng Company. The bull market for more than a year has given the securities industry an opportunity to redevelop. However, whether it is product innovation or standardized operation, higher requirements are put forward for IT construction and management. Securities companies have begun to realize that in the construction and management of IT systems, in addition to advanced equipment and technology, there must also be a set of standardized and manageable IT service management processes. In the process of securities trading operations, it is often encountered that due to system failures, deposits and withdrawals cannot be processed, stock quotes cannot be queried, and stock transactions cannot be carried out due to system failures. In order to solve the problem of many inconveniences caused to customers by system failures, enterprises must strengthen the construction and management of IT systems. Ensure the normal operation of the system, ensure the development of securities business, and promote the development of enterprises. However, construction and management are important, and scientific and effective management concepts are even more important.
The new generation of Skylake platform PR2510P in this project can realize a fast trading system, meet the system’s high requirements for the network, and need better stability and speed. In a diskless network, all files and data used by the workstation are provided by the server, and the server network card and hard disk speed will also affect the speed of the entire network, so the choice of server hardware is very important. In short, the basic implementation principle of PowerLeader’s diskless management system is to use the underlying technology to simulate the disk image file on the server into a hard disk through the network and start from it. The implementation level of the diskless management system is at the “controller/virtual controller” level of the computer system. Because it is under the hard disk controller, it is at the same level as the driver of the storage device hardware and the same as the implementation level of the real hard disk. Therefore, the virtualized hard disk through the network is the same as the real hard disk, and can be partitioned and formatted normally. It has the best software compatibility and supports any software that can be installed on a real hard disk.
The software system consists of a client system, an application server, a gateway and a market system. The market system includes a market transcoder and a market server.
1. Application server, market data storage and access, strategy management, T+0 transaction flow index;
2. Client: The client system provides users with a platform for displaying KinTrader functions;
3. Market information system, providing market information service functions;
4. Gateway, providing the transfer function from internet customers to counter systems and application servers
The overall network structure achieves the following goals:
1. In the Gigabit core multi-layer network architecture, the server is placed in the network core layer and connected to the core switch. This connection method is used to strengthen network data exchange and improve the efficiency of diskless network system.
2. In a network with multiple network segments or VLANs, diskless servers can cross multiple network segments in a cross-linked manner.
3. Use multi-server platforms to achieve network load balancing and enhance network communication efficiency and fault tolerance.
4. Use multiple server platforms to achieve network service backup and enhance the safety factor of network operation.
5. Realize centralized management of multiple network segments and multiple terminals
1. User stock software personalized data can be saved separately
The diskless management system uses server disk mirroring technology and network disk mapping function, so that the user’s personalized data can be saved in the server’s mirror file. The data saved by the user is as simple as operating on the local disk.
2. Highly secure stock trading environment
The operating system, trading system, personalized disk, and personalized program used by users are all obtained network image files, and the image files are generated in a packaged and encrypted form on the server. Therefore, users do not have to worry about leaks due to viruses. In combination with the firewall system in the network environment, the security of user data can be better ensured.
3. Simple and familiar operating system
The client operating system can be of various types, and users can freely choose a familiar one such as Windows 7 as the client system to operate.
4. Personalized office environment that can be recorded
The client can enable the super user function to install various office software. With various office environments and personalized disk functions, personalized office can be easily achieved.
5. Be fully compatible with the old transaction analysis system
The diskless management system provides multiple operating systems and multiple boot functions. It is compatible with the diskless multiple boot function.
6. The server has load balancing function
In a multi-user network environment, the server load balancing function added by PowerLeader server can make all servers in the network share the network burden equally to increase server efficiency.
7. The server can be backed up in real time
Blade has realized the real-time synchronization function of multi-server data in a multi-server network environment. When any server in the network stops working, other servers can take over its work and continue to provide corresponding data services to the client.
8. The client operating system can be restored by restarting the operating system
Users can set the user disk restore function to ensure that the client uses a unified system default image every time it starts. This function is similar to a hard disk restore card. Using a diskless management system can accurately restore the local system image and ensure that there is no damage to any hardware after multiple restores.
9. The server has multiple security solutions to deal with different levels of failure
PowerLeader servers have server load balancing and server data synchronization. In addition, you can choose RAID disk technology and server dual-machine hot standby technology to deal with failures of varying degrees, so as to reduce the loss of server data caused by different types of emergencies.
A diskless workstation refers to a workstation that has no local hard disk mounted. Through remote network boot technology (PXE), the server transmits the mapped mirror operating system to the local workstation through the TCP/IP protocol. Users can use the diskless workstation to run various types of operating systems and application software just like running a local disk, access and share network resources. The advantages of diskless workstations in the securities industry are: centralized management of client operating systems, unified distribution of application software, and synchronous update of application data.
Operating systems include Windows 8, Windows 10, Windows 2012, ServerWindows 2016 Server, Red Had Enterprise Linux, etc. According to the different needs of securities firms, multiple service platforms and multiple clients are combined; multi-client operating system dual boot function: Windows server + windows client/Novell DOS client, Linux server + windows client/Novell DOS client, Linux server + Linux client.
Whether it is a new system installation or software update, you only need to operate it once on a workstation, and in a blink of an eye, all clients in the network can be put into use. Network administrators no longer have to deal with each machine, and no longer have to run around every day to clone hard disks, install programs, and set up systems. Simplifying network management to basically managing servers, reducing the heavy system maintenance to a minimum, greatly improving the efficiency of system deployment, and saving manpower and costs. On the server management side, you can clearly see the operation status of each client, whether it is turned on, network usage status, and hard disk access status. You can also set how the client starts, whether to execute the automatic recovery function, etc. Provide intimate functions such as multiple network cards, multiple disks, and multiple configurations for servers to simplify the client configuration process.
It supports various types of computer hardware settings, so you don't have to worry about not being able to buy the same machine and not being able to match the original machine. And the system can automatically identify most workstations with different configurations, realizing plug-and-play.
