I have to present to management why our DR site is not up to par with our primary site and what we can do to get it there. Purchasing new hardware or adding additional resources to the current hardware which is AIX hardware:CPU,memory....etc. The DR site has last years model hardware while the primary site has the new model, faster/more CPU's. Of course $$$$ is always a factor so it needs to be justified. My summary which I have attached is lacking substance which is why I'm reaching out. Also what can we do from a software perspective to have an extra layer of security for our system, which I have documented some.
