How to manage high multiple servers?

There are two methods of expanding your KVM switch installation by adding additional KVM switches and thereby greatly increasing its overall capacity; cascading and daisy chaining.


Cascading KVM switches is a method of adding capacity to a KVM installation. It involves using a CPU port of the Parent KVM switch (one that is above a switch linked down from it) and connecting to a Child KVM switch. With numerous Child switches linked down from the Parent, the effect is reminiscent of the way water cascades down over a waterfall. Cascading can significantly increase the number of computers on an installation, however the Parent switch loses one CPU port for each cascaded KVM switch that is added.

Daisy Chaining

Daisy chaining is another method of expanding the capacity of a KVM switch installation. In a simple daisy chained installation, KVM switches are strung together in a chain similar to the way children make chains of daisies by tying the head of one daisy to the end of another. The first daisy chained KVM switch is called the Master unit and each subsequent unit on the chain is referred to as a slave. In a typical daisy chained installation, the total number of consoles is increased as the number of units daisy chained increases. The console that belongs to the Master KVM unit can also access and control all of the computers down the daisy chain installation. Daisy chaining preserves CPU ports by using Chain In and Chain Out ports to attach each daisy chained KVM switch.
