The basic concepts of KVM:
KVM means "keyboard, monitor and mouse." These three add up to a group known as the KVM console.
KVM switch is the main purpose of a unified group of KVM console can connect to many devices. This allows users to access and control from the console many computers or servers. Most of the enterprises need to implement the server behind the scenes to help the smooth operation of enterprises. The most common type of server, including mail server, database / file servers, web servers and application servers (SAP, ADP).
As a result of mission-critical enterprise server role, it is usually referred to as data centers or on the server room security environment.
Server room may be small cupboard or room, or it may be a lot of space, which contains hundreds or even thousands of servers. These are usually referred to as data centers. Data center is designed to protect the inside of the server, and provide very reliable power supply and generators; a high degree of physical security, as well as hot and cold high-end ventilation and air conditioning (HVAC) system.
KVM switch is to ensure that the main purpose of a KVM console can connect to many devices, allowing users to selectively from their control of a KVM console or another device.
The advantages of KVM switch:
KVM switches allow one or more users to access and control many servers, so businesses of all sizes can achieve the following advantages:
* To reduce costs - the use of KVM switch, no longer need to connect to each server keyboard, monitor and mouse, so only one or a small number of keyboard, monitor and mouse, you can control and management of many servers. This does not only reduce hardware costs, but also more valuable air space, in addition to electricity and also reduce the demand for air-conditioning systems.
* To enhance business continuity - KVM switch allows for "independent of the network" to visit the company's servers and other IT equipment. Switch itself does not need to rely on the enterprise backbone or network. Therefore, even if their own corporate network failure, IT personnel will still be able to access, control and management of the company's server. Can even make use of KVM switch from a remote location to do a full system reboot.
Not limited to the hardware platform and operating system - KVM switch can be in different server operating environment. And there is no restriction to a specific manufacturer's hardware or operating system can operate. Switch the operation of the enterprise IT environment can use many different manufacturers of servers, such as HP, IBM and Sun, a variety of operating system executable, for example, Solaris, Unix or Windows.
