What Is Remote KVM?

KVM, short for Keyboard Video Mouse, KVM can access and control computers by directly connecting keyboard, video, and mouse (KVM) ports. KVM technology does not require the target server to modify the software. This means that the target computer can be accessed at any time in the BIOS environment. KVM provides true motherboard-level access and supports multi-platform servers and serial devices. KVM technology has evolved from the original basic SOHO office type to an enterprise IT basic equipment room facility management system. Servers and devices located in multiple remote locations can be easily and directly accessed from the kvm client management software. The KVM over IP solution includes comprehensive multi-site failover capabilities, a direct interface to new server management standards (IPMI), and the ability to map local storage media to remote locations.

KVM stands for Keyboard,

KVM is an abbreviation for Keyboard, Video, and Mouse. The core idea of KVM technology is: to achieve centralized management of the system and network through proper keyboard, mouse, and monitor configuration; to improve the manageability of the system and the system

According to the network environment, it can be divided into: based on IP (KVM O IP) and non-IP;

According to the equipment environment can be divided into: mechanical and electronic (manual and automatic);

According to the installation method, it can be divided into: desktop and rack;

According to the working mode, it can be divided into: analog KVM and

1. Analog KVM technology

Analog KVM switch system directly connected to any computer

KVM basic function combination: KVM

The key points of KVM equipment's security access issues include: Does the software or system manufacturer of KVM equipment support continuous

KVM plays an irreplaceable role in enterprise network management, so many network managers need to choose such equipment to improve work efficiency. So what issues should be paid attention to in the procurement process?

1. Compatibility issues

Compatibility is an essential factor in all software and hardware purchases. This is even more important for KVM switches. The compatibility of KVM is mainly considered in two aspects. First, it must be compatible with various types of systems, including Windows, Unix, Linux, Novell, etc .; secondly, it must implement hardware compatibility with different keyboards, mice, and monitors. For keyboards, The mouse needs to consider the compatibility of different interfaces such as PS / 2 and USB.

2. Usability issues

The operation of KVM systems introduced by different manufacturers is different. Therefore, when purchasing, you first need to choose a method that is suitable for you to switch. For example, some KVMs are switched using keyboard hot keys, while others are switched through the OSD menu. When switching, you also need to check the comfort of the buttons, whether the switching is sensitive, and whether the buttons are flexible. In addition, the ease of use is also supported by whether hot-swapping is supported, because it is a common occurrence to add or remove some devices during the finishing process.

3 Signal degradation

For the low-end and middle-end KVM, the cables are directly connected, so the quality of the cable directly affects the signal transmission, especially when transmitting over a long distance, the cable requirements are more stringent.

4 Scalable problem

The scalability of KVM switches is also important, because with the development of the network, more and more host devices need to be managed. If the existing equipment does not support the cascade function, it means that it needs to be repurchased, which will increase A lot of costs. And the switch that supports cascading, just need to upgrade and expand according to the increased number of hosts to meet daily needs.

5. When purchasing KVM, you must cooperate with a large or large KVM manufacturer. When quoting, you must determine whether the price is with or without a line. Because the price of a line and the price of a line are sometimes very different, so the purchase Do nt just ask the price of KVM. What you need is the price with the cable, and how long is the after-sale warranty, whether there are invoices, etc. These are all things you need to know when purchasing KVM. The last thing you must add is that you must not be greedy for cheap. You must choose a company with strong technical service capabilities to cooperate.
