IBM xSeries and Netfinity Selection Guide
.
This chart 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 only, since each customer environment is unique and is unlikely to be precisely
represented by any of the specific applications in the chart. However by using the chart, it is expected that a reasonable approximation can be
reached. External Storage Units are utilised when internal capacities are exceeded. Basic guidelines on the use of the chart are given at the bottom of
the next page. These are not published benchmark results. Access: http://www.ibm.com/pc/us/techlink/srvperf.html to obtain benchmark data.
