Important Announcement: Community Back to Full Functionality
Dear Members, we are thrilled to announce that our Community is back to full functionality and that posts publication is now enabled again! We appreciate your patience during the last weeks. Learn more about our Community Guidelines. Thank you, Schneider Electric Community Team.
When talking about data center capacity, we talk about power, space or cooling capacity.
You may experience one or more of these typical power, space or cooling capacity issues in your data center (see screenshot).
When you have modelled the data center in IT Advisor, use the add-on capacity management module to design to solve these issues.
IT Advisor: Capacity makes daily tasks significantly easier for you by applying advanced calculations on your design. The asset provisioning functionality will guide you to obtain the optimum data center design, such as suggesting the best location for your next equipment because of the right amount of free space, cooling, power, and redundancy available.
Note: Using the Capacity module requires a preconfigured and valid power path, including an upstream connection to one of these power sources:
Input breaker on a PDU/Power Panel (assuming it is connected to the mains supply)
How does ITA know what the available capacity is?
The system calculates how much capacity is used to guide you on how much capacity is available. This happens automatically and you don't need to set anything up for the system to provide you with guidance, other than modelling your power equipment in the system, including correct breaker values, and a valid power path.
In addition to the power information available in each rack (physical breaker limits), the system relies on the enabled power capacity strategy for calculating estimated load. Again, you don't need to set anything up, and in most cases, you can go with the default settings. However, an option to change strategy is available if you want to explore other options.
Power information on equipment in the racks
The available capacity is defined by the physical breaker limits on the rack PDUs and receptacles in the racks, and upstream limitations (UPS capacity), or you can choose to introduce additional design limit configurations if you like to plan capacity based on custom predefined values on racks and rack PDUs.
