Requirements analysis
Library as important cultural facilities plays an important role in schools. And the computers used in traditional library electronic reading room cost a lot of manpower , material, financial resources and time for the unified deployment, security, and maintenance work, With the continuous expansion of library IT infrastructure, the insufficient IT managers, heavy task, workload, etc contradictions factors are outstanding. Main problems are as follows:

Difficult to deploy software
Due to numerous computers in library electronic reading room, in order to meet the software changing, improve the electronic reading room using effect, it is the necessary job to deploy and upgrade software for all computers, but it is a difficult job to deploy and upgrade software.

Numerous PCs in reading room, difficult maintenance job
Electronic reading room usually connects to internet through campus network, which is convenient for teachers and students to obtain information, and it is also easy to virus infection. Limited IT managers are exhausted in install operating system, system maintenance, anti-virus, update etc, it is challenge to improve the maintenance model.

Unable to provide a dedicated desktop
Students are unable to obtain a personal desktop for experiment, save personal data, homework, courseware design etc.

No fixed PC users
First, because the user is different, each computer should install different software for different computer need. In addition, because every computer users are not fixed, software and hardware are easy to be destroyed.

Electronic reading room PC performance couldn& acute;t catch up with the software update
Along with the continuous teaching software renewal, some new software or operating system cannot be installed on the existing computers. Electronic reading room computer should be updated often in a few years.

Energy consumption and noisy
Traditional PC energy consumption is 250w, the more terminal amount, the more energy consumption, In addition, PC is noisy, can& acute;t provide a quiet and comfortable reading environment.

Expensive operation cost
Due to hardware damage and frequently device changing, the electronic reading room PC should be replaced every 3 to 4 years, high TCO investment and software deployment, updates and patches requires IT managers to update frequently, different computer specifications requires IT staff to troubleshoot onsite, increasing the operating costs.

Solution

Desktop deployment in cloud

Link clone – fast desktop deployment
OS-easy E-VDI provides virtual machine link-clone function, which can easily make all kinds of library application desktop template, then IT manager can batch clone virtual machines according to the template with the same configurations, this desktops can be fast distribute to terminals via user name or MAC, it is rapid to deploy desktops environment.



?

A key to update-easily update system and software patches

E-VDI supports to edit system template; Install system patches, updates software in the template, using “a key to update& quot; to complete all the virtual machine maintenance, no need to go to terminal site to operate. Student can enter updated desktop which comes from cloud.

Daily cloud management

Management on cloud——any device, anywhere, anytime
With WEB-based graphical centralized management platform, managers can access the platform on any device has browser, they can execute physical server management, create, delete, and modify virtual machine, install virtual machine system and software; uniformly restrict end user’s computers. Enable to deploy and manage all desktops in office.

?

Cloud Management——USB control and terminal management
In desktop management platform, you can manage desktop USB permissions, manage terminal devices, and modify PC name, IP, remote startup/shutdown which can simplify library terminal management.

Dual desktop mode

Teaching desktop, meet the requirements of public reading desktop requirement
& quot;Teaching Desktop& quot; is equivalent to the public reading purpose desktop, administrator can customize the virtual machine restore policy, it can be restored by every time, monthly, weekly, be suit for public computers in library electronic reading room.

Personal desktop – meet for assignment, graduation design
In & quot;personal desktop& quot;, data will be saved permanently in virtual machine. Administrator can assign desktop account for students’ special need like software testing, homework, special design etc...

Guarantee cloud security

& quot;Dual system& quot; does not affect the teaching when network is disconnected.
While using the & quot;virtual desktop& quot;, you can also use the local system. The virtual desktop can be used for teacher’s office, browse, library management system etc applications, when network is interrupted, students can use the local system to complete the related work. It supports centralized maintenance, upgrade and other operations to local systems.

Flexible dispatch resource-improve resource utilization
When system or software upgrade causes the current hardware configuration is unable to meet the software requirements, the resources can be flexible allocated like elastically upgrade memory, CPU, etc., do not need to change the terminal hardware; In addition, & quot;dynamic migration& quot; function can be manually or automatically migrated the virtual machines to other server, & quot;load balancing& quot; function can automatically balance each server utilization to guarantee application running smoothly, meanwhile, maximize hardware use to make sure flexible use hardware resources,.

High availability-eliminate downtime
Teaching desktop has its restore mode, no matter whatever the users do, it will be restored to the original state to ensure system safety; & quot;virtual machine snapshot& quot; can restore the virtual machine to a specified point; when a single server failed, & quot;High availability& quot; will make virtual machine migrate to other running server automatically (require shared storage); & quot;System backup& quot; can easily complete the whole system data backup, even if the system collapsed, it can restore the data from the backup data.

Green,?Energy saving–low power consumption
It is more energy-saving to compare 15W cloud terminal to 300W traditional PC, the noise is reduced from 50db to10db at the same time, IT devices are more quiet, which achieves green reading. Cloud terminal with low price, free maintenance, low energy consumption advantages, it greatly reduces the computer lab cost from long-term investment prospective.

Smooth extension, extend device lifecycle
Traditional PC’s lifecycle is 3-5 years, cloud desktop life cycle is 5-8 years, it supports smooth upgrade; Only update the server configuration or add new servers without changing terminal devices.


Project value

Library: Construct new era, quiet and Green Library
Use cloud terminal to replace traditional PC, the average power consumption of terminal device is 15w (all-in-one device is 38w), the power consumption is 1/15 of the traditional PC, and the terminal integrated with mute design, help school to build a new era quiet library, green computing, energy saving, At the same time, improve service ability of the electronic reading-room, greatly save space, create a better students using environment.

Administrator: Cloud Management improves efficiency
Education cloud desktop solution improves the school library education device, IT management to a new era, build a centralized and unified cloud data center to provide better service for teachers and students, through B/S management platform, remote deploy and update desktops is realized, simplify IT procedure, at the same time, free-maintenance terminals can extend IT lifecycle, greatly improve maintenance and management efficiency, reduce operation costs, which leads IT management library to the cloud era.

Student: green, secure reading desktop
Cloud desktop construction creates a quiet and comfortable reading environment for students. Due to move the data from the IT environment edge to data center, it essentially reduced security risks faced by IT department. Virtual desktop operating system is stored in data center, compares traditional PC, not easy to attack by virus, greatly improves desktop system security. To sum up, cloud terminal creates green, quiet environment for the student, cloud desktop security and stability enhanced the students& acute; satisfaction.
