Redundancy concepts for maximum reliable systems in mission-critical areas
KVM is short for keyboard, video and mouse and refers to the interfaces of a computer. The special thing about the technology: based on hardware, KVM systems pick up computer signals at the interfaces from where they are extended and distributed.
They enable the spatial separation of operators and computers. This lets you move computer equipment from control rooms into dedicated, access-controlled server rooms. However, you can still operate the computers remotely – intuitively and in real time without latency or jolts and as if they were still placed next to the workstation.
KVM in mission-critical applications
For 35 years, G&D have stood for “German Engineering” and offer a comprehensive portfolio of KVM solutions for mission-critical applications. Their KVM extension systems, KVM switches and KVM matrices are available for applications needing to be extremely secure. The use of a KVM matrix, e.g. the ControlCenter-Compact, improves the IT infrastructure and harmonizes spatially distributed installations.
KVM matrix systems switch and distribute computer signals. They are used whenever several computers have to be operated remotely via different, simultaneous workstations. At the same time, users can operate many systems with a single set of keyboard, mouse and screen. All of this works completely without additional software installations and independent of the operating system.
Reliability through KVM redundancy concepts
Every day, G&D solutions prove their worth in numerous mission-critical installations. These can be air traffic control and traffic control, maritime and military control rooms as well as areas such as oil & gas and energy supply. KVM stands out especially when it comes to setting up a redundant system architecture to optimally implement security concepts. If a primary route, a computer or a workstation fails, operators can simply switch to a redundant route, a back-up computer or a redundant workstation. This way they can finish their work safely and in a familiar environment.
Of course, applications differ extremely when it comes to their complexity and requirements. Therefore, you can design set up different levels of redundancies. This way, you can back up either only the KVM system, the computer side, the console side or the entire application.
Security features for maximum reliable systems
KVM from G&D offers many aspects that improve cybersecurity and provide optimum access for being able to make quick decisions. The first and most important component is the separation of networks according to security levels. Since KVM systems are based solely on hardware, they only use original firmware instead of software that could be infected or manipulated.
To prevent unauthorized listening and access attempts, the data connection to the workstation is either uncompressed, transparent via fiber optic cables or compressed with data coding via copper cabling. For this purpose, G&D use their own video codec for additional security. A dedicated, proprietary network for the KVM systems keeps the networks separate.
Preventive monitoring in mission-critical areas
Using preventive monitoring lets administrators quickly react to critical conditions. This way, they detect exceeding temperatures, miscommunications with the keyboard interface, or problems with the redundant system before they lead to failures. The monitoring and SNMP function does not only avoid system failures. It also increases availability and allows system administrators to work more efficiently.
