Redundant PCs Accessed with one IP address

Can anyone point me in the right direction?

We are developing a redundant High Availability (HA) using multiple
Linux servers. Our development system is working properly so that if
a main server fails for any reason, another system(s) will detect this
and will become the main system without missing a beat.

My question is… How can the other computers (e.g. workstations) on the
network access the "main" system with one IP address when the "main"
system can change at anytime? Currently our workstations are aware of
the IP address for all the servers but it would be preferred that the
group of servers be considered one device and transparent to the
workstations.

Any help would be appreciated!

LVS is transparently moving the IP to another cluster member.
