KVM-Over-IP Guide Remote Server Access (KVM Over IP) products are a new breed of non-intrusive hardware based solutions which allow you both in-band and out-of-band access to all the servers connected to your KVM switch. Utilizing advanced security and regardless of operating system, these KVM Over IP products allow you to remotely control all your servers/CPU's – including pre-boot functions such as editing CMOS settings and power cycling your servers. These KVM Over IP products allow you access via your internal LAN/WAN, and connectivity via the Internet or dial in access via ISDN or standard 56K modems.
Access to the IP KVMs is secured with militiary grade network security.
Contents. Etymology Before the mouse became relevant in server switching applications, the term Keyboard Video Switch (KVS) was used to describe keyboard and monitor switching devices.
With the increased adoption of Microsoft Windows, the mouse and other I/O ports in peripheral switching became prevalent. Remigius Shatas, the founder of Cybex (a popular peripheral switch manufacturer at that time) expanded the initialism to Keyboard, Video and Mouse (KVM) in 1995. Some years later, Universal Serial Bus (USB) began to become the new industry standard for connecting computer peripherals. As a result of the growing need to switch peripherals (such as touchscreens) in addition to the keyboard, mouse and monitor, some companies are now selling 'KVMP' switch devices (standing for keyboard, video, mouse and peripheral). This section possibly contains. Please by the claims made and adding. Statements consisting only of original research should be removed.
(June 2014) With the popularity of USB—USB keyboards, mice, and I/O devices are still the most common devices connected to a KVM switch. The classes of KVM switches that are reviewed, are based on different types of core technologies in terms of how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. (USB-HID= USB Human Interface Device) USB Hub Based KVM Also called an Enumerated KVM switch, a connected/shared USB device must go through the full initiation process (USB enumeration) every time the KVM is switched to another target system/port. The switching to different ports is just as if you were to physically plug and unplug a USB device into your targeted system. Emulated USB KVM Dedicated USB console port(s) are assigned to emulate special sets of USB keyboard or mouse switching control information to each connected/targeted system.
Emulated USB provides an instantaneous and reliable switching action that makes keyboard hotkeys and mouse switching possible. However, this class of KVM switch only uses generic emulations and consequently has only been able to support the most basic keyboard and mouse features. Semi-DDM USB KVM Dedicated USB console port(s) work with all USB-HID (including keyboard and mouse), but do not maintain the connected devices' presence to all of the targeted systems simultaneously. This class of KVM takes advantage of DDM (Dynamic Device Mapping) technology. DDM USB KVM Dedicated USB console port(s) work with all USB-HID (including keyboard and mouse) and maintain the connected devices special functions and characteristics to each connected/targeted system.
This class of KVM switch overcomes the frustrating limitations of an Emulated USB Class KVM by emulating the true characters of the connected devices to all the computers simultaneously. This means that you can now use the extra function keys, wheels, buttons, and controls that are commonly found on modern keyboards and mice.
Mechanical switch for keyboard (serial, PS/2 connector) and video (VGA, DE-15 connector) KVM switches were originally passive, mechanical devices based on multi-pole and some of the cheapest devices on the market still use this technology. Mechanical switches usually have a rotary knob to select between computers. KVMs typically allow sharing of two or four computers, with a practical limit of about twelve machines imposed by limitations on available switch configurations. Modern hardware designs use active electronics rather than physical switch contacts with the potential to control many computers on a common system backbone. One limitation of mechanical KVM switches is that any computer not currently selected by the KVM switch does not 'see' a keyboard or mouse connected to it. In normal operation this is not a problem, but while the machine is booting up it will attempt to detect its keyboard and mouse and either fail to boot or boot with an unwanted (e.g. Mouseless) configuration.
Likewise, a failure to detect the monitor may result in the computer falling back to a low resolution such as (typically) 640x480. Thus, mechanical KVM switches may be unsuitable for controlling machines which can reboot automatically (e.g. After a power failure).
Another problem encountered with mechanical devices is the failure of one or more switch contacts to make firm, low resistance electrical connections, often necessitating some wiggling or adjustment of the knob to correct patchy colors on screen or unreliable peripheral response. Stuhrling prestige automatic. Gold-plated contacts improve that aspect of switch performance, but add cost to the device. Most active (electronic rather than mechanical) KVM devices provide peripheral emulation, sending signals to the computers that are not currently selected to simulate a keyboard, mouse and monitor being connected.
These are used to control machines which may reboot in unattended operation. Peripheral emulation services embedded in the hardware also provides continuous support where computers require constant communication with the peripherals. Some types of active KVM switches do not emit signals that exactly match the physical keyboard, monitor, and mouse, which can result in unwanted behavior of the controlled machines. For example, the user of a multimedia keyboard connected to a KVM switch may find that the keyboard's multimedia keys have no effect on the controlled computers. Software alternatives There are alternatives to some of the functionality of a KVM switch, such as, and, which does the switching in software and forwards input over standard network connections. This has the advantage of reducing the number of wires needed. Screen-edge switching allows the mouse to function over both monitors of two computers.
Remote KVM devices. This section does not any. Unsourced material may be challenged and. (August 2010) There are two types of remote KVM devices that are best described as local remote and KVM over IP. Local remote (Including KVM over USB) Local remote KVM device design allows users to control computer equipment up to 1,000 feet (300 m) away from the user consoles (keyboard, monitor and mouse). They always need direct cable connection from the computer to the KVM switch to the console and include support for standard between computers and users interconnected by the switch device. In contrast, powered KVM devices are able to control computer equipment using a combination of USB, keyboard, mouse and monitor cables of up to 5 metres (16 ft).
KVM over IP (IPKVM) KVM over IP devices use a dedicated micro-controller and potentially specialized video capture hardware to capture the video, keyboard, and mouse signals, compress and convert them into packets, and send them over an link to a remote console application that unpacks and reconstitutes the dynamic graphical image. This KVM over IP subsystem is typically connected to a system's standby power plane so that it's available during the entire BIOS boot process. These devices allow multiple computers to be controlled locally or globally with the use of an IP connection.
There are performance issues related with LAN/WAN hardware, standard protocols and network latency so user management is commonly referred to as 'near real time'. Access to most remote or 'KVM' over IP devices today use a but can even switch between two or more hard drives, although many of the stand-alone viewer software applications provided by many manufacturers are also reliant on. Security Note: Some KVM chipsets or manufacturers require the 'whitelisting' or authority to connect to be implicitly enabled. Without the whitelist addition, the device will not work. This is by design and required to connect non-standard USB devices to KVM's. This is completed by noting the device id's (usually copied from the Device manager in Windows), or documentation from the manufacturer of the USB device.
Generally all HID or consumer grade USB peripherals are exempt, but more exotic devices like tablets, or digitisers or USB toggles require manual addition to the white list table of the KVM. In comparison to conventional methods of remote administration (for example or ), a KVM switch has the advantage that it doesn't depend on a software component running on the remote computer, thus allowing remote interaction with base level settings and monitoring of the entire booting process before, during, and after the operating system loads. Modern KVM over IP appliances or switches typically use at least 128-bit data encryption securing the KVM configuration over a WAN or LAN (using ).
KVM over IP devices can be implemented in different ways. With regards to video, KVM over IP cards use a form of where the PCI KVM over IP card would access and copy out the screen directly from the graphics memory buffer, and as a result it must know which graphics chip it is working with, and what graphics mode this chip is currently in so that the contents of the buffer can be interpreted correctly as picture data. Newer techniques in management subsystem cards and other implementations get the video data directly using the bus.
Implementations can emulate either or based keyboards and mice. An embedded server is typically used for the video protocol in and implementations. KVM sharing devices KVM sharing devices function in reverse compared to KVM switches; that is, a single PC can be connected to multiple monitors, keyboards, and mice. While not as common, this configuration is useful when the operator wants to access a single computer from two or more (usually close) locations - for example, a public kiosk machine that also has a staff maintenance interface behind the counter, or a home office computer that doubles as a.
