1.1 About the ActiveScale X100
The ActiveScale X100 is a 42U, scalable, object-based data storage system that allows you to easily keep
up with data growth and deliver on your business objectives.
The minimum configuration is equipped with one sled column in all six Storage Enclosure Basics and
provides either:
• 0.84 PB of data storage capacity using 10 TB HDDs.
• 1.008 PB of data storage capacity using 12 TB HDDs.
• 1.176 PB of data storage capacity using 14 TB HDDs.
Multi-site systems can achieve a maximum storage capacity of either:
• 52.92 PB (raw) using 10 TB HDDs.
• 63.504 PB (raw) using 12 TB HDDs.
• 74.088 PB of data storage capacity using 14 TB HDDs.
Note: 12 TB HDDs require ActiveScale OS 5.3 or later. 14 TB HDDs require
ActiveScale OS 5.5 or later.
The Storage Enclosures are connected using two 48 port System Interconnects.
ActiveScale X100 systems are equipped with ActiveScale OS software.

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
Weight • Minimum system weight3—1572 lbs (713 kg)
•Full system weight—2227 lbs (1010 kg)
•Delivery weight (system and packaging)—2457 lbs (1114 kg)

2.Rackless system height can vary based on the installation. A rackless configuration uses 36U of equipment.

1.5 Available kits and upgrades
This section describes the upgrades and supplemental kits that are available for the ActiveScale X100.
1.5.1 Scale up kits
Each scale up kit contains additional sleds that increases data storage capacity by either:
• 0.84 PB using 10 TB HDDs.
• 1 PB using 12 TB HDDs.
• 1.18 PB using 14 TB HDD’s.
For more information, refer to Installing scale up kits on page 139.
1.5.2 Scale out kits
Storage capacity can be even further increased by connecting a new ActiveScale X100 to an existing
system.
For more information, refer to Installing scale out kits on page 152.
1.5.3 Rack seal kits
You can use the rack seal kit to seal racks with third-party, liquid-cooled doors.
For more information, refer to Installing rack seal kits on page 165.
1.5.4 System Expansion Node kits
System Expansion Node kits contain one additional System Node for your ActiveScale system. Additional
System Nodes allow you to increase system performance with your existing storage capacity. Up to three
system expansion kits (three additional System Nodes) can be added to a base ActiveScale system.
For more information, refer to Installing System Expansion Node kits on page 168.

2.1 Management Interconnect
The Management Interconnect is used for IPMI control and monitoring of the System Nodes, Storage
Nodes, and PDU components. It is connected to System Interconnect 1 and the SFP connector.
Note: The Management Interconnect is non-redundant as it is not a critical
component.
