defines system entities and their relation for the purpose of system configuration and 
management. The System Description is read in once at system start-up and from that time on 
stored in persistent memory.

Distribution of NCS Services in the Avantellis 
System
Many NCS services are subdivided into subparts. All subparts together form one NCS service. 
The subparts may run together on one node or may even be distributed among several nodes. 
This section will provide more details. 
The following figure provides an overview on how NCS services are distributed in a system. 
2.2.1
NCS Directors
A Director for a particular NCS service manages and coordinates key data among the other 
distributed subparts of that service. The Director is located on a system manager node and is 
implemented with a 2N redundancy model.
