IBM xSeries and Netfinity® 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 on the following
page.
