Multiple computer environments are commonplace for data centers – it generally accommodates tens of thousands of routers, servers and switches, which forms the backbone of network that serving critical business operations. Businesses tend to invest a great bunch of money in hiring IT professionals and technicians to keep these devices running properly. Since the amount of devices in data center continues to grow, to reduce the cost and clutter at the workspace becomes critical. This situation creates a need for efficient keyboard, video, and mouse switching, thus KVM switch emerges as an ideal solution.
It may help to begin by defining what a KVM switch is: KVM stands for keyboard, video and mouse. To put it simple, a KVM switch is a device that designs to control multiple computers form a single keyboard, video monitor and mouse console – and with no special software or hardware modifications to the attached computers. By utilizing KVM switches, one can achieve the control of computer at all stages of operation. In this way, it reduces the number of keyboards, monitors and mice needed to control multiple computers, along with the cost and issues in regard to manage those devices. It can be beneficial in places where there are no sufficient room for multiple monitors and keyboards, such as in a server room rack or on a small desktop.
KVM switches are commonly used in environments where one user needs to operate two or more computers, or where one or more administrators manage multiple computers from a central location. Which include data centers, network operating centers, server rooms, department LANs and any desktop with multiple computers. KVM switches provide an immediate hardware cost savings by eliminating the need for separate keyboards, video monitors and mice. However, its benefits are not limited to this.
Eliminating equipment space: sometimes users have to deal with more than one platforms or with multiple computers, KVM switch in this case helps to reduce the clutter of multiple monitors, keyboards and mice. Fewer keyboards, monitors and mice therefore makes for less racks, cabinets and floor space needed.
Increasing user productivity: KVM switch effectively reduces user time spend traveling from one control location to another. The extended control supported by KVM switches enables that computers located in one area to be controlled from another location.
Enhancing Energy Efficiency: These devices streamlines data center design by freeing up valuable desk and rack space. By reducing hardware redundancy, less power will be consumed due to the lower total electrical load. So it also reduces an organization’s power and cooling expenses.
With the benefits of convenient, economical and space-saving, KVM switch also has the necessary flexibility to be used in any home office, small/mid-sized or enterprise application. Meanwhile, a KVM switch is easy to install, configure and operate. Over the years, it gains in much popularities among users who have upgrades their home computer systems and still want to use their old computers – KVM switch just eliminate the need to purchase a second keyboard, monitor and mouse. And businesses that want to save money when one person use more than one computers are also more inclined to adopt KVM switch. They are frequently used in server rooms where it is only necessary to periodically access each server one at a time, or in data centers where multiple servers are placed in a single rack with a single keyboard, monitor and mouse. Data center managers then can connect to any server in the rack by using a KVM switch.
KVM switches are often found in data centers where multiple servers are placed in a single rack. By pressing a button on the kvm switch, the administrator can change control from one server to the next. Using a KVM switch can save the administrator the cost of purchasing a dedicated keyboard, monitor and mouse for each computer, save space in the server room and limit cable clutter.
The number of computers a KVM switch can control ranges from 2 to 32. Enterprise-level KVM switches can also be daisy-chained or cascaded to allow even greater numbers of computers (over 500) to be controlled from a single keyboard, monitor and mouse console. Simply by connecting KVM switch to computers that you want to control using Cat5 Ethernet cable or special KVM cable kits. A keyboard, monitor and mouse console are then connected to the KVM switch, or in some cases the console is built into the KVM switch. Control is switched from one computer to another by the use of a button, On-Screen Display (OSD) controls, or hot keys on the keyboard, with the KVM routing signals between the computers and the keyboard, mouse and monitor console.
With unsurpassed advantages like space-saving, economical and energy efficiency, KVW switch is stretching its reach to medical center, industrial applications and military by providing secure and reliable access to multiple computers. Whether you’re in the next room or halfway around the world, you’ll be able to access your servers through it. We can expect the future of KVM switch to be bright and prosper. It you haven’t integrated KVM switches into your data center design, it’s time to consider.
