There is also a method of providing a single KVM 150 using the KVM multiplexer 140. And, there is a method of providing a single KVM dedicated server 240 via a network. Figure 1 is a number of KVM (50) to match the number of servers 10, 20, 30, 40 can be used in the same manner as the existing server 10, 20, 30, 40 according to the prior art A diagram showing how to provide (60) (70) (80). As shown, KVM 50, 60, 70, 80 also increases when the number of servers 10, 20, 30, 40 increases. Therefore, operational and management problems are raised. In addition, the KVM 50, 60, 70, 80 is present in various places, serious problems in manageability, such as frequent shifting of the manager position. As a method for this, a method of using the KVM multiplexer 140 has been proposed. 2 is a block diagram illustrating a method of providing a single KVM 150 using the KVM multiplexer 140 according to the prior art. As shown, several KVMs are connected to one KVM multiplexer 140, and a set of KVMs 150 are connected to the KVM multiplexer 140. Then, the switch of the KVM multiplex 140 is changed. Thus, a method of performing input / output while allowing a set of KVMs 150 to be sequentially connected to a plurality of KVMs 1: 1. This method is easy to configure and manage. However, a separate multiplexer 140 is required, and there is a limit to the number of KVMs 150 that can be connected to the multiplexer 140. Therefore, the scalability is limited, and the available area is limited by the limited distance of the VGA signal. 3 is a block diagram illustrating a method of providing a single KVM dedicated server 240 via a network according to the prior art. Recently published schemes connect a plurality of servers 200, 210, 220, 230 and a separate server 240 to centrally manage KVM tasks for the servers. When the KVM 250 is used for each of the servers 200, 210, 220, and 230, the processing flow is passed through a separate KVM server 240 connected through a network. Thus, a method of supporting the KVM 250 for each server 200, 210, 220, 230 has been proposed. This solution provides the convenience of administrators. In addition, remote management through a network is possible. However, a separate network for KVM 250 management should be provided.
