Applications
After more than 20 years of development, Boya has continuously and deeply grasped market demand and accumulated a large number of customer resources and rich service experience.
Guiyang Public Transport Group Project
Case Background
Guiyang Public Transport (Group) Co., Ltd. was established in 1951. As an urban public transport operator, the company undertakes public transport passenger services for the production and travel needs of urban citizens. The company currently has 9,324 employees and 2,753 retired employees. The total assets amount to 988 million yuan, with 3,239 operating vehicles of various types, 159 urban and suburban lines, an operating mileage of 231 million kilometers, and a total operating income of 621 million yuan.
With the rapid development of the city, the business volume of the public transportation group has increased rapidly. In order to ensure the normal operation of the city’s public transportation system, the stability of the application system and the security of the data have become increasingly important. The city currently has more than 3,200 public buses and nearly 10,000 employees, carrying more than 3.4 million citizens in Guiyang City to travel by bus, with an annual passenger volume of 609 million. After the issuance of IC special bus cards in 2001, IC bus cards for major banks and financial institutions were launched again in 2012. With the rapid growth of business volume, GPS vehicle positioning intelligent dispatching and IC card systems have been greatly tested.
case analysis
In view of the current IT status and applications of the bus group, server virtualization is based on the high-performance servers and storage independently developed by Boya, combined with VMware virtualization technology, to propose a new generation of IT architecture that effectively combines server virtualization technology with online storage, thereby realizing centralized management of various business systems, ensuring data consistency, security and reliability, and establishing a powerful, high-performance and reliable data storage core platform.
The bus group currently has three core systems:
(1) GPS vehicle positioning intelligent dispatching system;
(2) IC card system;
(3) fuel supply system;
The three major systems are the key to ensuring the normal operation of the city’s public transportation system. Any downtime caused by hardware and software factors will affect the operation of the public transportation system, or even paralyze the public transportation system. In order to ensure the high reliability, high continuity and high stability of the group’s business application system, the PowerLeader four-way server PR4840R and PowerLeader fiber storage GS5120FD are used to build a VMware virtual architecture data center. It brings a continuous application environment, high operational efficiency, and integration of idle system resources to the public transportation group.
solution
The system architecture of the server virtualization integration solution is shown in Figure 1, which mainly includes the following components:
1. Use the PR4840R independently developed by PowerLeader Computing to provide high-performance and high-density physical servers. Configure 4 high-configuration servers to install VMware Standard Edition to provide advanced virtualization functions such as high availability.
2. The back-end uses the company’s new generation unified storage product GS5120FD storage as the shared storage of the virtual server to provide storage space for virtual machines and ISOLibrary.
3. Configure backup storage for the GS5120FD shared storage to perform real-time data backup of the storage to protect the security of the storage data and provide reliability of the business system.
4. Use ordinary fiber switches to achieve redundant connection between storage and servers, and provide storage space for VMware servers through FC-SAN.
5. While ensuring the high reliability of shared storage, back up some business systems to the data storage GS5120FD, and further protect the application data of the system through FC-SAN.
6. Install the VCenter console on the management terminal to achieve centralized management of VMware through a dedicated management network.
Customer Benefits
Rapid deployment, safe and reliable VMware installation can be completed in 10 minutes, and business virtual machine creation can be completed in 2 minutes. The management panel is easy to use and has no single point of failure. Vmotion can quickly realize business backup and fault recovery, and the system is safe and reliable. Improved application availability By deploying VMwareHA (high availability) architecture on the system, the risk resistance of these systems is improved; at the same time, combined with the snapshot function of the storage system itself, data security is also improved. Easy to manage and improve efficiency After the integration is completed, both VMware and data storage can be managed in a unified manner, reducing the daily workload of administrators and greatly improving IT integration efficiency. Flexible expansion With such an architecture, whether it is for future storage expansion or the introduction of other solutions due to business development needs, it can be deployed quickly and flexibly. 5. Energy saving, emission reduction, and cost reduction Use the green energy-saving server PR4840R independently developed by PowerLeader Computing to deploy multiple business systems on the same server to make full use of server resources and reduce energy consumption. Effect after virtualization
Comparison before and after virtualization | Traditional physical server method | After server virtualization | expected result |
Resource Utilization | <20％ | >90％ | Each server 4.5 times improvement |
24 hours power consumption (W) | 20 business servers 550W*24*20=264000 | Resource pool consisting of 4 servers 15 businesses are running VM1200*24*4+530W*24* 3=153360 | Save 42% |
Business Server Preparation cycle | 15 working days | Within 1 working day | 94% reduction |
Maintenance efficiency | <10 units / person | >30 units / person | 3 times improvement |
Data Security | Data is scattered, management is difficult, and business interruption recovery is slow | Centralized control, storage backup, application backup, business independence, Service 0 downtime | Increase N times |
