Figure 10-20 Changing a 31-node CES system to an SP system
Recommended expansion plan
If you are thinking of scaling up your CES system to an SP system in the future,
you have to plan out appropriate frame numbers and switch port numbers for
your Enterprise Servers so that they will still be valid when you add SP frames at
a later time.
There can be many expansion plans. An expansion plan could be considered
when you plan to upscale from a CES system to a switchless SP system.
Another expansion plan could be considered when you plan to upscale from a
CES system to a switched SP system
Both expansion plans take in consideration numbers such as:
򐂰
Size of CES
򐂰 Frame/Node Type
򐂰 Frame Number
򐂰 Node Number
Attention: You have to plan the appropriate frame and switch port numbers
that will work in an SP system with SP frames when you first install your CES
system. This way you can migrate to an SP system without having to
reconfigure your Enterprise Servers that are already installed.
