about KVM over IP, that is, the solutions for KVM control through network IP. In fact, many people in enterprises and computer room management have heard of it but are not very clear about what is going on and how to choose such problems. Simply put, it is a combination of traditional KVM switches and network technology, which allows users to control another computer or server from anywhere with a network, even from a distance, such as crossing half of the earth. Does this sound particularly convenient?
Why do you have to work hard to use KVM over IP? You think, if the machines in the computer room are piled up like mountains, it would be very troublesome to walk around and plug in cables! Also, can’t the administrator stay in the computer room overnight every day? With this, you can do the server's operation such as turning on and off at home or on the way to a meeting in another place by taking a laptop or mobile phone – it's simply too easy!
What points should you pay attention to when choosing ? This is too critical, otherwise it will be useless to buy the wrong one and spend money, and it will also delay things:
1. Resolution – It is important whether the picture displayed after connection is clear. If the text is blurred, how can you do it? Generally, it must support at least 1920×1080, and better 4K must also be available, and choose according to your own equipment situation;
2. Delay situation – The karaoke will definitely not work during operation. The mouse will be moved for a long time before it can react. It will be so anxious! Therefore, if the delay is low, it is best to control it within a few dozen milliseconds, otherwise it can drive people crazy;
3. Number of supported devices – How many servers or computers do you have to control? Buying a type of person who can only control one or two units is definitely not suitable for large companies. You have to see clearly how many ports a single machine can support at maximum and whether it can be expanded in a cascading manner;
4. Security – After all, data is transmitted through the Internet. What if someone peeks at it or hacks come in? Therefore, there must be encryption functions, such as SSH and SSL, and user permission management must be supported!
Tips to solve small problems encountered in daily use:
• What should I do if I can’t connect to the device? First check whether the target device's power supply is plugged in or whether the network cable is loose. Then ping the device IP is connected or not, and there may be problems with the browser or client version too low. Try updating it.
• Is the picture pattern flashing around? Check whether the VGA/HDMI cables on both ends are oxidized when they come into contact with poor interfaces. It is likely that they can be better if they change the cable or re-plug them;
• The mouse and keyboard did not respond? See if the USB port is disabled in the device settings. Another possibility is that it is because of compatibility issues. You can solve it by changing to a general mouse and keyboard driver – I have encountered this situation before and have been struggling for a long time
Sometimes, people will confuse KVM over IP and remote desktop software, which are different
| Comparison items | KVM over IP | What about ordinary remote desktop software |
|---|---|---|
| Is it operating at the bottom? | Yes, just manage the hardware | No, the operating system needs to be started |
| Does BIOS support? | Must support! System installation is indispensable | Not supported, can't enter BIOS |
| What is the quality of the picture? | High definition, no compression and very smooth | It will compress, the picture quality is worse |
Provide global procurement services for weak current intelligent products! As I used it, I suddenly found that the device interface was not suitable. My family had HDMI. As a result, the KVM I bought was VGA, and I was stunned! Don’t worry about returning goods at this time and waste money. You can buy an HDMI to VGA adapter. It can solve the problem for a few dozen yuan – remember, when buying, you must see clearly whether the adapter supports high-definition resolution, and don’t get into the pit again! If the company purchases equipment in large quantities in large quantities and cannot handle it, you can also find a professional service provider to consult and select, which can avoid many detours. Generally speaking, it is better for medium and large enterprises to choose rack-type models, which can save cabinet space; for small and medium-sized companies or individuals, it is enough to use a desktop-style small box, which is cheap and easy to use to meet basic needs.
