Tivoli newbie

We're about to set up TSM for the first time.  I was surprised to see in
the installation guide that 12gb of RAM is required for 6.2  The server
that we were planning on using only has 4gb - it's an IBM 7026-6H1 -
with a 2-way 1.2ghz power4+ processor.  I don't see anything in the
installation guide that mentions requirements for processor power.  Does
anyone know if this server will be sufficient?
