VNX Sizer an easy to use presales tool which recommends a VNX, VNX-F or VNXe system for a specified workload description. Workload descriptions can be very simple, using the Data Decay method, or more detailed, using the Application Oriented method. In either case, the inputs are presented in terms a businessman would understand. Best practices create the proposed solutions. Modify these results with a risk profile to vary solutions to more aggressive, less costly options to more conservative solutions with higher resiliency and cost. The user has control over the configuration chosen and has a range of possible solutions, with metrics by which to rank them. Choose rank by relative cost, power, capacity or performance. The VNXSizer displays its information in a graphical format and offers an HTML reporting capability for detailed accounting.
