The passage around this formula

The staffing and inventory implication follows directly: staged spares reduce mean time to repair, and mean time to repair is exactly as load-bearing in the availability term A as mean time to failure is. A cluster with excellent hardware reliability but a slow spares and dispatch process will show the same effective availability as a less reliable cluster with fast repair, because A is a function of the ratio between the two, not of either one alone.
