Long range raid configuration

Is it possible to configure a raid setup between two computers over a network? Basically I want whatever happens on one computer to happen on the other and be able to switch between them. Thank you.

A RAID array employs the use of a hardware raid controller on a single machine.  This controller takes inventory of local drives to create a virtual disk.  So, to answer your question, no this is not possible.

You might be able to leverage some sort of image copy on a scheduled basis between the computers

What you are referring to is called Clustering. Where several server machines replicate the changes on each member of the cluster.
With a RAID you cannot do this.
If you are looking for a failover solution then configure RAID1 mirror which will let you get quickly online if one drive fails.

Thank you. I think the best solution for my issue would be an extended KVM switch or remote login.

Actually comment # 42385992  just isn't correct.  RAID arrays neither require a single machine nor a hardware controller.

It should be empirically obvious that Google has RAID arrays and your data is not located on a single machine.  There are hardware RAID controllers that support multiple machines.  There are software RAID stacks that support multiple machines.
