The StarTech.com SV831DUSB StarView USB KVM Switch allows you to control up to eight USB or PS/2 connected computers from one console (keyboard, mouse and monitor). It can be cascaded with multiple KVM switches (each sold separately) to give you control of up to 64 computers. Hotkey commands or front panel push buttons make switching between the PCs easy. This 8-port KVM switch with OSD comes with a security option to password-protect select computers from unauthorized use. It also features the configurability and convenience of an on-screen display, which lets you name the connected PCs. This rack-mount KVM switch is made with a durable all-metal chassis. It can be mounted into 1U of cabinet space and because it is OS independent, there is no need for software or drivers.
