KVM switch is an advanced hardware solution in modern server management. With a KVM switch, the administrator can easy access and manage up to thousands of servers or PCs from a single keyboard-video-mouse console. KVM switch is widely used in SOHO, small and middle- sized enterprises as well as large global enterprises. The modern cooperate service room or data center benefits a lot from the application of the KVM switch, it saves much energy and space, which eliminates the need for a separate keyboard, video and mouse. What’s more, the application of the KVM switch central management simplifies the administrator’s work flow and improves the production efficiency. With the economic globalization and the trend of network popularization, the KVM over IP solutions with remote management function will be better choice for enterprises to manage computer rooms in different countries.

KVM devices are widely used in managing computer rooms in enterprises and public institutions; it largely increased the network administrators’ work efficiency. As KVM products are more and more important in modern computer room management, so what we need to pay attention to when purchasing KVM products?

 

1.Compatibility

Compatibility is a key factor when purchasing KVM switch. KVM compatibility refers to whether the KVM switch is compatible with different operation systems, such as Windows, UNIX, Linux, etc., whether the KVM switch is compatible with different monitor, keyboard and mouse, such as USB and PS2 keyboard/mouse have different compatibility.

2.Easy to use

KVM products from different manufacturers have different operation systems, a suitable switching way is very important when choose a KVM switch. For example, computer switching via keyboard hot keys, OSD menu or special push buttons. Comfortable and flexible switching keys and hot pluggable support are important factors we need to pay attention when choose a KVM switch.

3.Signal Stability

For the middle and low-end KVM switches, KVM signal quality largely depends on the KVM signal cable, especially in long distance transmission. So it’s important to choose high quality KVM signal cables.

4.Cascade Functions

With the development of modern computer rooms, more and more servers need to be managed, KVM cascade functions becomes more and more important in modern computer room management.
