The point is to put an entire SCM (Supply Chain Management) solution on a single box so hardware assets can be shared. We virtualize many different servers and run them concurrently on the same box. The system uses on average about 75% of the CPUs when I tune it correctly. It hits 90% at month end audit time. By having so many, certain components can dynamically borrow spare CPU cycles from other systems on the same box and run at 200%, 500%, 900% of their entitled capacity if needed. This one will have 4 SAP SC application servers, 2 IBM virtual I/O disk servers, 2 IBM virtual I/O network servers, a SAP central instance, and an Oracle 11g database server all virtualized and plugged into our Nexus core via an aggregated 40Gb/Sec ether-channeled connection.
Then we will build another identical system for fail over purposes.
