Location definition
For the purpose of this example the primary locations to be modelled will be the UK, New York, Europe and the primary and secondary data centres. These locations have been chosen to illustrate the use of different usage patterns across time zones, as well as to allow the effect of adding disaster recovery planning to be considered. For later use each of the locations also has a network node defined. In this case the nodes have simply been numbered sequentially for each of the locations. This will be discussed in more detail later.

Once the function, behaviour type and usage pattern data have been provided the model starts to produce useful information based on its estimations. The most important of this is the daily function usage estimation. This information is presented on the “Estimated Function Demand” sheet within the model, and provides as estimate, by year, of the average daily usage for each function. This is then used to provide an estimate of the average and peak operations per second for the system. Continue reading ‘Example: User demand estimation’ »

I will skip the title sheet, which is merely descriptive, and start to work with the function definitions. In this case I highly recommend starting with a few key functions that are likely to provide the majority of the key performance behaviour. If this model turns out to be insufficient at a later stage then add more information as the model develops. This means that the level of detail being worked on remains manageable.
