The sockets refers to the literal, physical CPUs.  Virtual CPUs (for
guests) or cores do not count.  Unless your running some kind of mainframe
you will likely have a server with anywhere from 1-2 sockets.  My
understanding of the licensing is that you pay for the
host/hypervisor/machine to have RHEL, plus however many guests the license
includes.  So 4 or unlimited.

Example: my server has 2 sockets, 4 cores each.  If i paid for
RHEL unlimited guests on 2 sockets...I could have only 2 virtual machines
each with 4 virtual CPUs, or 8 VMs with 1 vCPU each.  That's still within
the license.  Sockets is referring to the things that are LGA775 or AM3+.
