GOAL or METRIC: 6.09% of total IT spend or less
RATIONALE: The data network is the backbone of the data center, and is a critical component of how it performs. But if it is inefficient, support costs will certainly increase. This metric is a good indication of how well the system is running. Higher costs are a sign if poor health, and the need for engineering improvements. As always, the more resources are used to support inefficient processes and technology, the less that can be used on innovation and infrastructure improvements.
