2 Part B: System Dimensioning
This chapter provides information about limits, restrictions and tools that will help to
dimension projects with Desigo CC.
Desigo CC is a memory-based management platform. Each physical or logical
entity in the system is represented by a system object allocated in memory.
Hardware requirements for Desigo CC Server depend primarily on the number of
system objects it shall manage (system size).
The current Desigo CC version supports up to 150,000 system objects per system
(project). However, up to 450,000 system objects could be reached with a single
server by using a distributed system configuration where several Desigo CC
systems are running at the same time (segmented configuration, see Distributed
System Configurations [➙ 29]).
Another, although minor, factor that impacts on Desigo CC dimensioning is the
number and type of clients.
Finally, the required disk storage space needs to be considered. Disk storage
space is needed for historic data kept in the SQL server and for project data,
including attachments and documents.
2.1 Hardware Category Definitions
This section provides minimum hardware specifications to run Desigo CC given a
certain amount of system objects. The amount of system objects consumed by a
single system can be calculated by using the Desigo CC dimensioning tool
described in section.
The use of this tool is specially needed to calculate the correct amount of disk
space needed when the system is using Long Term Storage / archiving
functionality.

The disk space required may vary depending on
project size and requirements related to the setup
of data storage and backup strategy. The given
figure for the minimum disk space is just an
average recommendation.

Typically, customer installations are very vital over the whole lifecycle. We
recommend providing for reserves for the future and consider a higher hardware
category than originally designed.
We recommend to use the latest generation of processor available. The use of
more cores does not lead to better performance.
