Hyperview provides a Rack Space KPI widget on the location and rack dashboard that contains metrics for Rack Space Efficiency and Rack Utilization. What is the difference between these two values, and how are they calculated?
1 Answer
The Rack Space KPIs widget in Hyperview that is available for location and rack dashboards contain two similar, yet different values. One of the values is Rack Space Efficiency which offers insight for how well the space within the rack is managed, and the other value is Rack Utilization which provides a capacity metric based on total rack units.
Rack Utilization
This calculation is based on the count of total rack units within a rack compared to the used space from devices within the rack. The calculation does not account for contiguous space within the rack, only the total RU used versus available.
Formula
(Total RU Consumed / Total RU Capacity) * 100
Rounded to the nearest whole percent.
Example
Rack Total RU Capacity: 42 RU
Rack Total RU Consumed: 34 RU
(34 / 42) * 100 = 81% Rack Utilization
Rack Space Efficiency
This calculation is based on the efficiency of mounted assets within the rack. It compares the rack's largest contiguous space and total available space in it's calculation, and therefore provides a relative value based on where the assets are placed within the rack instead of total contents of the rack itself.
Formula
(Largest Available Contiguous Rack Space / Total Available Rack Space) * 100
Rounded to the nearest whole percent.
Example
Rack Total Available Space: 8 RU
Rack Largest Available Contiguous Rack Space: 3 RU
(3 / 8) * 100 = 38% Rack Space Efficiency
