KVM switches

Developers first placed KVM switches in Ahmedabad complete microcomputers on cards and packaged them in standard 19-inch racks in the 1970s soon after the introduction of 8-bit microprocessors. This architecture operated in the industrial process control industry as an alternative to minicomputer control-systems. Early models stored programs in EPROM and were limited to a single function with a small realtime executive.

The KVM switches in delhi hasVMEbus architecture (ca. 1981) defined a computer interface which included implementation of a board-level computer installed in a chassis backplane with multiple slots for pluggable boards to provide I/O, memory, or additional computing. The PCI Industrial Computer Manufacturers Group PICMG developed a chassis/blade structure for the then emerging Peripheral Component Interconnect bus PCI which is called CompactPCI. 

Common among these KVM switches in kolkata chassis based computers was the fact that the entire chassis was a single system. While a chassis might include multiple computing elements to provide the desired level of performance and redundancy, there was always one board in charge, one master board coordinating the operation of the entire system KVM switches in Hyderabad.
