Clusters and Servers
Sentriant AG introduces clusters and servers. A cluster is a logical grouping of one or more ESs that are
managed by one MS.
A single-server installation is one where the MS and ES are on one server. The ES is assigned to a
Default cluster. This configuration is illustrated in
A multiple-server installation is one where the MS is on one server and there are one or more ESs on
separate servers. Each ES must be assigned to a cluster. This configuration is illustrated in
The responsibilities of the MS and ES are as follows:
MS
●
Configuration
■
NAC policies
■
Quarantining
■
Endpoint activity
■
License
■
Test updates
■
ES
●
Testing
■
Access control
■
The quarantine method is defined per cluster; all of the ESs in a given cluster use the same quarantine
method (Inline, DHCP, or 802.1X). When using multiple clusters, each cluster can have a different
quarantine method. Clusters cooperate to test and control access to the network, although the ESs in
each cluster are not able to communicate with any ES in any other cluster.
