The KVM (keyboard, video and mouse) has dramatically changed in the last few years as the pressure for more effective use of datacenter power and space has grown.  Where as a keyboard and mouse switch, with a standard keyboard, mouse and small 14/15 inch monitor was ok, we’ve moved on to flatscreen 1u alternatives, or even more recently the network attached kvm, where the kvm is attached not with the big kvm cables but a network cable, much more efficient from a cabling perspective.

Relatively easy wins with significant savings can be made by consolidating your kvms to fewer more populated kvms and by using flatscreen based 1u kvms. Although replacing the kvm by using the lights out functionality that is on most new servers is a more effective use of the network patching, space and power in your datacenter.

Consolidating kvms, making one kvm host three cabinets in the meantime though, until you can virtualize the infrastructure, or use lights out only, makes sense, just make sure there is some kind of logic so when it’s 3am and you’re trying to reboot a server/see what’s on the screen it doesn’t take a long time for the engineer to find it..
