The KVM switch is a hardware input device that allows the user to exercise control over multiple computer using a single video monitor, mouse and keyboard.
Keep in mind below things for select best KVM Switches.
1. Digital vs. Front-end IP products: If you want to use switch over IP, you can choose between pure digital applications and front-end IP products.
2. Support for Audio: Some KVM switches keep audio support. For example, UltraView Pro series will support audio for users and computers.
3. Integration of Remote Power Management Functionality: By integrating a remote load device, administrators can cycle power to a server from a user station or through an internet browser from any location worldwide.
4. Security/Authentication: Most KVM over IP devices allow an administrator to leverage existing authentication schema.
5. The Number of Users: Multi-User switches range from smaller 4-Port able to handle dozens of servers, to integrated KVM systems capable of allowing hundreds of administrators to control thousands of servers.
6. CAT5 Switches: CAT5 dramatically reduce desktop and server rack cable clutter and allow users and computers to be situated farther apart than they could be using standard KVM cables.
7. Resolution and Performance: Resolutions vary by device; some product over IP switches provide a maximum of up to 1600X1200 at 60Hz over IP.
8. Support for Serial Devices: Some High-End KVM Switches enterprise solutions provide support for serial devices (routers, headless Unix, etc.) Avocent and Raritan devices provide support for serial devices through the use of dongles.
9. Bandwidth: Bandwidth requirements will vary significantly depending on the graphic intensity of the application you are using.
10. Distance Requirements: The maximum distance between a user and server with a CAT5 KVM switch varies, with some high-end analog CAT5 KVM switches.
