The Data Streaming Bus (DSB) cluster technology allows you to improve retention and performance. It also increases reliability by adding fault tolerance and data replication. For more information, see Trellix Enterprise Security Manager Installation Guide.

The data is received from the data devices and then sent to the cluster only once.

The devices that can be linked to a cluster are:

  • ERC

  • HA ERC

  • ELMERC

  • ACE

  • ADM

All the communication between the cluster is secured with IPsec. Communications from outside the cluster are secured with SSL.

The following are shared between the nodes that form the cluster:

  • Broker organization tasks

  • Data and balance load

  • Configuration and data enrichment.
