Having deployed NightWatchman across an estate of nearly 50,000 PCs globally and seen a 40% reduction in PC energy consumption, CSC engaged with 1E on a NightWatchman Server Edition pilot across 86 servers in three data centers and four server rooms. The pilot found that 11% of servers were unproductive more than 75% of the time and 22% were wasting energy more than 85% of the time.
