1.Values are for one additional node. System Expansion Node kits can contain up to three additional nodes.
2.Rackless system height can vary based on the installation. A rackless configuration uses 36U of equipment.
3.The minimum system weight does not include the rack and PDUs

1.3 Airflow requirements

Ensure that both the front and rear of the ActiveScale X100 stay clear of any materials that may block or
disrupt the airflow in any way. Disrupting the airflow can cause the system to overheat, which may affect
performance or cause damage to the system.
The following rack airflow principles should be considered for best results:
• Controlled air conditioners that are functional and can sufficiently maintain specified system
operating temperatures should be located in the facility where the system will be installed.
• The airflow in and out of the equipment must not be restricted.

1.4 Servicing space requirements

Space at the front and the rear of the system is required to service system components. The front space
requirement is based on the length of the longest system component, plus the space necessary to fit a
