IBM xSeries Selection Guide
This graph represents general guidelines for selecting the appropriate server based on the number of users that can be supported in a particular application
environment. This chart is for general guidance since each customer environment is unique and is unlikely to be precisely represented by any of the specific
applications in the chart, but by using the chart, a reasonable approximation can be derived. External Storage Units are utilized when internal capacities are
exceeded. Utilize the chart by following the steps outlined at the end of this section.
