What Is a KVM Switch and How Does It Work?

Today, data centers and companies have to deal with the space limitation of lots of computers. They need a method to control the increasing numbers of computers and other networking devices efficiently. KVM switches are invented to combat this issue that is taking up valuable space and time. So what is a KVM switch and how does it work?

Figure: KVM switch is widely used in our life.

What Is a KVM Switch?

What is KVM? KVM stands for keyboard, video and mouse. And as for what is a KVM switch, it’s technically “keyboard, video and mouse switch”. KVM switch is a hardware device that allows users to control different computers through one set of keyboard, video monitor and mouse. This is the KVM over IP solution, which is very useful if the server settings are located off-site and you don’t want to drive over there each time when you need to make changes. The switches will be assigned an IP address and accessed from any place in the world with the right username and password.
In addition, we should note that, although KVM switch and Gigabit Ethernet switch both can control multiple computers or servers, they are different devices. KVM switch is usually considered as a hardware device, which is popular when people have upgraded their computer systems or add new computers but don’t want to invest in a second keyboard, display and mouse. While Ethernet switch is regarded as a central hub. Commonly, it’s connected to each computer or network device in an Ethernet. Therefore, they are two different devices with different functions.

How Does KVM Switch Work?

We have a good understanding of the question what is a KVM switch. It can control more than two or greater numbers of computers(over 500). Users can use Cat5 cables or the specific KVM cable kits to connect the computers to the KVM switch. Then, connect the keyboard, display and mouse console to the KVM switch. If the switch is equipped with the console, this step could be skipped. Now users can use a button, on-screen display controls or hot keys on the keyboard to switch from one computer to another.

Which Type of KVM Switch Do I Need?

Designed for various end-user needs, there is a considerable choice of KVM switches on the market. Before buying, you should consider:
  • How many computers do I need to control?
  • What type of KVM switch do I require?
  • Do I need an on-screen display?
Use the table below to help you make a suitable decision.

All these KVM switches are made by FS.COM, which can be accessed from any computer on the LAN, WAN or Internet. With easy installation and use, they’re the optimal solutions for controlling up to 8 or 16 computers or servers.

Conclusion

What is a KVM switch? It’s an ideal tool for saving time and energy when lots of computers or servers are involved. To find out more about our KVM switches with high performance, as well as other networking options like 10Gb Ethernet switch, patch panels, please visit FS.COM.

What Is VLAN Switch and Why Do We Need It?

图片
VLAN or virtual LAN is a type of LAN that is defined to map workstations based on everything except for geographic location. It develops when the network has increased in size and complexity, and many companies require more access ports or a network design. Basically, it’s a networking technology which allows the network to be segmented logically without geographic restrictions. But how much do you know about VLAN switch? What Is  VLAN Switch? VLAN switch is built on the fiber optic switch  of LAN, which realizes the division and management of logical working group as a software. As defined in IEEE standard 802.1Q, VLAN switch can provide a way to transform one network into multiple broadcast domains. And each broadcast domain is usually matched with IP subnet boundaries, so that each subnet has its own VLAN. Therefore, users can obtain various wired LANs for different purposes that are co-existed physically, which means you don’t need to buy additional hardware or c...

Differentiate the 3 Technologies: Switch Stacking vs Cascading vs Clustering

图片
When we have more than one switches on hand we often seek to a better way in making use of them and managing them. There are mainly three technologies that we might use when we interconnect or combine several switches together, which are switch stacking, cascading and clustering. For many people that firstly get in touch with these terms, they can’t figure out the differences between them. Some discussions of the switch stacking versus switch clustering and switch stacking versus switch cascading have been put forward, but a comprehensive comparison between them has not been made. So this post is a discussion of switch stacking vs cascading vs clustering. Switch Stacking vs Cascading vs Clustering The comparison of switch stacking, cascading and clustering should be based on knowing the meaning of these technologies. So firstly we will see what switch stacking, cascading and cluster are. What Are Switch Stacking, Cascading and Clustering? Switch stack...

Nylon Zip Ties vs Hook-&-Loop (Velcro®) Ties

图片
The confinement system is the last but critical part of the entire cable management systems. Cable tie plays a very important role in this part. However, there are various types of cable ties in the market. Which one is better? Since nylon zip ties and hook-&-loop (Velcro®) ties are most common and controversial. This tutorial will compare these two types of cable ties in details. Overview of Cable Ties Cable ties are cheap and simple components used in cable confinement system. They are usually the last measure to ensure the cable managed in order. Cable ties are available in a variety of sizes and materials for use on different applications with different requirements. In addition, there are various of color options for cable ties. These color codes help users to manage the cabling and achieve easy troubleshooting. The most commonly used formats of cable ties are nylon zip ties and hook-&-loop (Velcro®) ties, as the Figure 1 & 2 shown: Figure 1. Drawin...
