Analog KVM and Digital KVM

KVM stands for keyboard, monitor and mouse, that is, using a set of keyboard, monitor or mouse to control multiple computers, and plays an important role in remote scheduling and monitoring. KVM technology can send various data in the dispatching information network to the remote terminal, which provides convenience for the subordinate agency, so that even if the subordinate agency does not establish a dispatching data network, the information can be shared.

1. What is the digital KVM?

With the rapid development of the information technology era, the mode of the data center in the computer room is diversified, which also allows the operators and engineers have more options to choose from. Analog switching solutions with modular KVM over IP capabilities and digital switching solutions with integrated KVMoIP have their own advantages. An analog KVM solution is usually best for small to medium data centers. Digital KVM solutions are best suited to support large data centers across the country or around the world.

2. What are the differences between analog KVM and digital KVM?

A brief analysis of some of the key differences between analog KVM and digital KVM:

First point we start with analog KVM. Its access or connection is independent of the network and is not limited by network control. The advantages of this are better video performance or usability, unobstructed access, and lower network width requirements. But, the disadvantage is that it requires more Cat6 cables and components. The application scenario like a Control Room's data center with about 300 server, which allows up to 32 Operators to connect at the same time.

Digital KVM were developed as the development of IT technology. The advantages of digital KVM are that there are fewer cables, easy expansion, higher cost-effectiveness. However, when we use the existing LAN infrastructure, its access or connection will be within the network and limited by the network. At the same time, users will also be limited by KVM over IP, such as delay, cable quality, consumption of network bandwidth, limited availability of access blocking console, etc. But for example, enterprises with more than 500 servers, more than 50 Operators or multiple locations with simultaneous online or unmanned server room can be applied.

You can use digital or analog solutions independently, or a combination of the two, depending on your business needs. You can connect a handful of servers to one or two switches to consolidate through analog KVM, or connect many data centers located in different locations from digital KVM, or design your own solution that combines analog and digital KVMs.
