Foreword

A large national English training company, in order to change the way the manual hard disk transmits data. The Group Huis network storage server is used to build a private cloud environment for enterprise data exchange, which improves the security and privacy of enterprise data information, thereby improving the efficiency of employees and allowing employees to spend more time and energy on teaching. Quality improvement, research and development and innovative educational products and services to better provide scientific teaching solutions.

Customer background

The client is a national large-scale English training company, focusing on providing English-speaking, multi-disciplinary teaching and training services for children aged 2-15 in Beijing, Nanjing, Suzhou, Chongqing, Qingdao, Shenyang, Hefei, Changzhou, Kunming and Wuhan. Educational institutions have been established in more than 30 cities including Nanchang, Guangzhou, Inner Mongolia and Changsha. The original local data backup intercommunication mainly transmitted data to the storage server at the headquarters through manual hard disk copy. The headquarters is located in Beijing, with more than 30,000 students and more than 2,000 employees. The courses involved are as many as 15 years of primary, intermediate and advanced systems and stages.

Business challenge

The English Training Enterprise is an education and training company that specializes in providing English-speaking, multi-disciplinary teaching services to children aged 2-15. The company will encounter many challenges in the face of the construction of private data exchange within the enterprise, especially the following five points:

1, there are stagnation points all over the country, need to synchronize data in different places

2. High security requirements such as teaching materials, student materials, and corporate information

3. Data sharing and efficient interoperability of employees in different places

4. Authorization of training teachers, employees, trainees, etc.

5, the amount of data is large, the teaching documents are improved and stored in different versions.

solution

According to the business needs of the English training enterprise, the large amount of visitors, and the need for data intercommunication, considering that the public cloud uploading and downloading data involves privacy and account security issues, the English training enterprise finally passes the Synology NAS network storage server. Solve the private cloud construction of enterprise data exchange.

First, the Group's Beijing headquarters of the English training company purchased two Synology DS3617xs, and built a dual-system hot standby environment through the High Availability Manager suite to achieve high availability and redundancy of local data, which better ensured data security.

Secondly, 300 DS1517+ (8GB) were purchased and set up at the educational and training institutions' offices around the country, and the DS3617xs of the headquarters realized data exchange with each other, breaking information islands, achieving data intercommunication and improving efficiency.

The following is the network topology diagram of the Group Hui private cloud construction solution of the English training enterprise:

High privacy of corporate information

The security of teaching materials is the primary issue considered by the English training companies. The original manual hard disk transmission method is not safe and easy to leak data information. The public cloud uploading and downloading is also easy to disclose accounts. As a private cloud server, Synology NAS can not only have a unified storage space for data, but also solve the hidden problem of data leakage that often occurs in public clouds. This is an important reason for the English training enterprises to choose Group Hui to centrally store and manage data.

High security of enterprise data information

In the remote data sharing private cloud construction environment provided by the English training enterprise, the two Synology DS3617xs servers are merged into one High-Availability cluster, one as the active server and the other as the standby passive server. The active server handles all data storage, requests, and services. At the same time, all content is continuously replicated to the passive server, which is "two-node hot standby." The benefit of this is that there is no data loss due to service accidents. For data-life-oriented training organizations, security and reliability are always important reasons for purchasing decisions.

Synchronization and sharing of teaching information

There is a principle in data management, that is, what can be done by the "machine" and handed over to the "machine". New teaching courseware, student information and other "data" updates. If the traditional manual method is adopted, it will inevitably lead to information asymmetry leading to a decline in teaching quality. A better way is to set up a synchronization plan to open up mutual departments and regions. The state of isolation makes sharing between data more efficient and smooth. This requires the use of Synology's Cloud Station ShareSync suite.

In the specific application, the group headquarters of the Beijing headquarters is set to "host" and establish a connection (client) with each education branch NAS, which can seamlessly synchronize all teaching data and solve the core of teaching data management. Courseware distribution and file synchronization issues, such as:

The English training company's newly revised January 2018 Children's English (7 years old) teaching courseware may have to be distributed by means of mail, manual hard disk copying, uploading to the cloud disk, etc., which inevitably leads to special circumstances such as missing information and stolen accounts. After that, it takes a lot of time to confirm the communication. Now, you only need to store the file in the specified shared file in the "master server", so that you can implement between NAS (master server) and NAS (client). Synchronization, open the high-speed channel of information transmission.

Similarly, for the excellent teaching experience, teaching case or student data of the branch, you can also achieve "bottom-up" backup and synchronization through Cloud ShareSync, and even enable SSL-encrypted connections for important data such as student data. The security of the connection.

Whether it is top-down or bottom-up, the English education and training company collects and distributes data to the NAS (client) of all branches through the headquarters NAS, which not only ensures that all data has a backup version and is safely stored on the remote NAS. , also achieve efficient distribution and synchronization of teaching materials.

Through Cloud Station Backup, the important data on the PCs of the employees and lecturers of each organization is collectively uploaded and backed up to the NAS. There is no need to worry about the data being scattered everywhere, and the version of the teaching videos and materials cannot be kept uniform.

Each file can also support up to 32 historical versions, allowing you to restore files to a desired version at any time with an intuitive timeline display.

Improvement of teaching efficiency

Imagine that in the traditional teaching process, if A teacher wants a certain teaching material, she may only let B teacher transmit it by QQ, etc. by phone, mail, etc., or take a hard disk to copy, in this case. In the meantime, Synology solved these time-consuming and inefficient things in two simple steps.

First of all, it is the allocation and management of accounts.

With the Synology DSM operating system, it is easy to assign an account and set permissions for each faculty member.

At the same time, user groups can be set according to different classes, disciplines and even regions, and the access rights of shared folders can be assigned.

By sharing the folder, the account with the specified permission and the user group can access the content inside. For the teacher, as long as the data is transferred to the shared folder, other teachers in the same group can conveniently access it. , browse and download.

After completing the setting of the shared folder, all the teaching materials can be safely stored in the NAS. The lecturers are no longer wasting time copying the data, but can concentrate more on how to improve the teaching. Quality.
