Nodes

Overview

In Bazefield, a Node refers to a server running the DataEngine Service. Linked Nodes form the core of data transfer within the system.

There are three types of Nodes: Edge Buffers, Storage Nodes, and Proxy/Master Nodes. The Web Server is not considered a Node, as it does not use the DataEngine Service to store or forward data—except in the case of an all-in-one Master Server that hosts the Bazefield Portal, DataEngine Service, and supporting services.

Nodes are typically virtual machines, except Edge Buffers, which are usually physical mini-computers on a plant’s SCADA network. However, Edge Buffers can also be virtual, depending on customer needs.

Administration

In the Bazefield Portal, Administrators manage Nodes using the Device Management application. When adding a Node, they choose from three types: Data Buffer, Storage, or Master. Only one Master Node is allowed, but multiple Storage and Data Buffer Nodes can be added to match the system architecture. Usually, each plant or SCADA system has its own Data Buffer Node.
