What confuses me is following (Taken from
http://www.redhat.com/rhel/server/compare/):

Under "Technical capabilities" it that page it is mentioned that "Red
Hat Enterprise Linux server" supports "Up to 2 sockets", while "Red
Hat Enterprise Linux Advanced Platform" supports "Unlimited" sockets.
Socket is described as

"A Socket is the physical connection(s) on a computer system's
motherboard that is designed to hold a central processing unit(s)
("CPU") regardless of the number of logical CPUs recognized by the
computer system from that physical connection. Note that the socket
capacity refers to the maximum number of processors that the server
can be configured with, not the actual number. Consequently a server
can be upgraded with additional processors with no change in
subscription."

Acording to this Enterprise server should support up to 2 physical processors.

So if I understand this properly, you can install Enterprise server on
4 processor box (as I have here) and they will work, but that
configuration is unsupported by Red Hat. To have proper support, I
would need to have Advanced platform there ?
