Hi all,

can anybody explain me the trade off between a KVM switch and the use
of a Desktop sharing software such as VNC viewer ?

For one thing, it's going to take a lot of bandwidth to display the
remote desktop on your current one - and it will be relatively slow
because of that. A KVM switch physically changes your connections from
one machine to the other so you are always operating 'locally' - no
additional overhead.

Unless you've got an enterprise grade server, desktop sharing software
won't allow you to watch the BIOS level boot process.

KVM is limited to connecting local (as in same desk/room) machines but has
no performance overhead. VNC has performance penalties but can connect any
machines on the internet.

Sure, a KVM switch is a hardware solution and is generally used locally with
instant response times. Sometimes they are IP enabled and accessed by VNC anyway
but usually they are used locally. Using VNC tends to be slower and more limited
and gets you less access than a KVM switch. For example, you can't generally get
into the BIOS on a machine when using VNC as the server runs on the operating
system that hasn't yet booted. Using a KVM switch, you can get into the BIOS and
if it's IP enabled then you can get into the BIOS from a remote location.
