Revision A
Defining Customer Requirements
VSM Sizer Tool
As shown in Figure 2-2, the VSM Sizer tool requests inputs on mount activity, file size, the
estimated growth rate of data, and the current configuration of libraries, transports, and
cartridges to determine customer requirements for a VSM5 system.
Based on the results of its calculations, the tool identifies an optimum VSM5-VTSS config-
uration and minimum number of RTDs to meet the defined requirements. The tool also
suggests possible hardware reductions that could result from installing the proposed
VSM5 system.
