The XIV system is designed to comprehensively tackle each storage TCO factor, in
multiple ways, as delineated below:
Figure 2: How XIV storage reduces TCO
The result is that the XIV system succeeds in dramatically improving each TCO factor
(with the exception of fixed factors, such as hardware maintenance) while other storage
systems typically focus on reducing only one or two cost factors. For example, even if a
system’s upfront cost is largely discounted, its TCO will still be high due to ongoing
administration and maintenance costs; a system with improved performance often has
higher environmental costs.
By taking a balanced and comprehensive approach to reducing all cost factors, the XIV
system succeeds in dramatically reducing TCO where other systems fail.
