Storage managers spend a lot of time thinking about the storage volume managed per employee, often measured as terabytes per full-time employee (TB/FTE), as a metric of storage management efficiency. Variability in measurement methodology and environment-specific factors make it difficult to accurately benchmark the metric and use it as a point of comparison across environments. While it is useful to look at the TB/FTE ratio at a given company, it should be considered along with other key performance indicators to be a valid gauge of storage management efficiency. When it is given too much weight in management decision-making, it is all too easy to have numbers that obscure, rather than reveal, true management effectiveness.
