How to safely, centrally, and effectively achieve unified management of servers, networks, power supplies, and other equipment in central and regional data centers has become a that data center administrators are eager to solve. Although using a KVM switching system can solve this problem, traditional analog KVM systems, while able to achieve basic switching functions, have drawbacks:

1. Complex wiring makes expansion and modification difficult, making it hard to manage thousands of devices.

2. Channel congestion and geometric cost caused by expansion cascading are unfavorable to protecting investments.

3. The number of users will be limited, which is unfavorable for multi-user management. Centralized management of multi- branch server rooms cannot be achieved. The flexibility of user access is limited, making it difficult to achieve deep-level management (BIOS access, VM functions, etc.).

4.-level cascading will increase the system failure rate. It is difficult to provide remote access to manage an unlimited number of servers distributed in any region at any time and from any location

5. Security is relatively poor, whereas a digital KVM centralized control system based on TCP/IP can completely eliminate the above drawbacks and meet the diverse needs of customers.

Highdefinition digital KVM solves the construction challenges of campus server rooms

         As server rooms accommodate more and more servers, and the types of servers inside the cabinets are increasingly updated, the first second-generation KVMs from the original analog stage can no longer meet the needs of the server room. For example, the second-generation USB KVM supports a maximum distance only 5 meters, and the PS/2 KVM supports a maximum distance of only 15 meters. Given the current scale of server rooms, due to the placement of in parallel, medium and large server rooms simply cannot be controlled by a single second-generation KVM. Therefore, the third-generation digital KVM was born

The digital KVM switch centralized remote deep management system has the following advantages:

I. Complete centralized authentication

Fully digital IP technology enables digital remote users to uniformly manage all devices in the server room through a centralized secure authentication system. It ensures that all users must pass strict permission verification by authentication server before accessing terminal devices. Only after passing can they access servers and devices with corresponding management permissions, avoiding unsafe direct access to KVM switches by numerous users. This maximizes the systems security performance while supporting local operations within the server room.

II. Reasonable switch port ratio

Considering the impact of overly concentrated server equipment in educational institutions' data centers on overall environment and load factors, rationalizing the KVM switch port ratio effectively avoids issues such as ventilation, power supply, temperature, and weight-bearing problems caused by excessive equipment concentration This reduces the operating costs of the server room and maintains a good overall environment.

III. Unified platform integrating multiple server room resources

School data centers may contain various models and brands servers and network equipment, each with its own management interface, which is unfavorable for centralized management. The KVM centralized control system supports multiple servers and other hardware devices, multiple hardware (including SUN, PS/2, USB, and Console port interfaces), and multiple operating systems. It also supports serial devices (minicomputers, network equipment, etc.), end-users with a unified platform that integrates multiple server room resources. This allows all servers, minicomputers, serial devices, and network equipment in the server room to be fully on a unified platform, perfectly integrating with other hardware facilities in the room to truly achieve complete control over the server room's system resources.

IV. Simplified and standardized server room

The CAT5 series uses standard CAT5 cables as signal transmission lines for keyboards, monitors, and mice, thereby standardizing the server room's integrated wiring system. Naturally, within the same cabinet can also use KVM devices of the same brand to reduce costs. Furthermore, CAT cables can connect remote hosts and servers via the enterprise Ethernet, with a maximum distance of several hundred meters, significantly extending the distance between administrators and servers.

In addition, the network-based KVM solution eliminates the hassle of network administrators frequently entering and the server room. Network administrators no longer need to travel all the way to the server room to reboot crashed servers, nor are they limited by traveling back and forth between different server room locations Instead, every MIS personnel can fully control remote server hosts through their own computer screens, including: CPU, hard disk usage, fan speed, operating system, FRU device status, network card operational data.
