Prepare for hardware replacement
Hardware replacement overview
The content in this document is directed at customers who are responsible for replacing Dell EMC
PowerProtect X400 capacity cube and X400 platform cube components.
The X400 capacity cube provides the deduplicated storage capacity, in a scale-out model, to
support a wide range of data protection capacity needs. It is a 2U single-node Dell EMC
PowerEdge R740xd server. An X400 capacity cube can be either a Hybrid or All Flash model. The
Hybrid model is referred to as the X400H capacity cube and has a maximum useable capacity of 96
TB. (The term Hybrid refers to the fact that the cube contains hard disk drives (HDDs) for main
data storage and solid state drives (SSDs) for performance optimization.) The All Flash model is
referred to as the X400F capacity cube and has a maximum useable capacity of 112 TB.
A PowerProtect X400 Appliance includes one X400 platform cube and one to four homogeneous
X400 capacity cubes. The minimum appliance configuration is one X400 platform cube and one
X400 capacity cube for a total of 4U. The maximum appliance configuration is one X400 platform
cube and four X400 capacity cubes for a total of 10U. X400H capacity cubes and X400F capacity
cubes cannot be mixed in the same X400 Appliance.
For more information on the X400 platform cube and X400 capacity cube hardware components,
see the PowerProtect X400 Appliance Hardware Configuration and Installation Guide .
