We are customer-centric and provide customized or one-stop full-stack solutions to empower all industries.
In the application system of universities, a large number of application servers and a large-capacity storage system are needed to centrally store important information of various business and management systems of universities.
Campus network server requirements: According to the college construction plan and the progress of infrastructure construction, the investment in teaching resources and the number of students entering, the campus network construction planning and equipment matching work are carried out as planned. As a campus network server device, it is indispensable. The servers required are WEB servers (domain servers, DNS servers, and proxy servers can be merged into WEB servers); campus OA, mail servers; video on demand; WEB servers (domain servers, DNS servers, and proxy servers can be merged into WEB servers); campus OA, mail servers; video on demand; personnel management, teaching affairs and student status management, one-card system, financial servers, backup servers, computer classroom servers, network billing servers, distance learning servers, one-card enhanced system servers, online examination servers, video broadcast servers, network video conferencing servers, video on demand servers, VOIP servers, IP SAN storage devices, etc. can be purchased selectively according to actual needs.
This solution mainly includes a database dual-machine high-availability subsystem, an IP-SAN storage and backup subsystem, and a load-balanced Web publishing subsystem. Considering the reliability and stability of the system, it is recommended to use a redundant structure to improve the overall reliability of the system and configure a dual-controller disk array for the storage system. Through the data protection system including the backup system, complete and reliable data protection is provided for each application system running on the database business system operation platform.
The topology of the entire system is shown in the figure above. Two four-way PR2865P database servers are used as dual-machine hot standby to prevent unexpected downtime of critical data applications. The entire system is equipped with an IP-SAN storage GS-9124v2 for global data backup. The entire system is equipped with a set of ARRAY’s TMX load balancer to achieve load balancing of the system network. A set of Windows Server 2008 integrated servers is used to achieve high availability. For the expansion model selection of the WWW server, DNS server, DHCP server, video server, and backup server in the core campus network computer room of the university, we recommend the Intel IA architecture 2U dual-way storage server PR2012P with excellent cost performance, which expands the new 64-bit technology, allowing users to enjoy 64-bit throughput efficiency with the most economical investment.
PowerLeader's efficient server platform solution provides key virtualization functions through Windows Server Hyper-V, allowing you to integrate roles scattered across multiple servers into different virtual machines running on a single physical server. This solution can help you reduce server sprawl and maximize the use of current physical hardware. Each server can run in its own independent environment, which can achieve higher security and easier management.
The equipment used in the cluster focuses on green energy conservation, selects low-power components, and adopts professional heat dissipation design to avoid unnecessary energy loss; PowerLeader PDCM intelligent power consumption control system can adjust the power consumption of the entire system in real time according to the cluster load, achieving 20% energy saving without affecting the performance of the cluster, truly realizing green and high-efficiency computing.
Supports centralized user management, device management, storage management, and image calling, changing the drawbacks of decentralized management of previous analog systems and greatly improving management efficiency and scheduling capabilities
