ztC Edge System Description
Stratus Redundant Linux software runs on a single ztC Edge computer, also referred to as a physical machine (PM) or node. The single-node ztC Edge system provides easy installation as well as virtualization and monitoring capabilities. You can add a second PM to a single-node system to configure a dual-node ztC Edge system (after this system reconfiguration, you need to apply an updated license). On a dual-node system, you can create fault-tolerant or highly available Virtual Machines (VMs). (A single-node system is simplex, so VMs are not fault-tolerant or highly available.) Both PMs in a dual-node system:
- Run the same host operating system (Ubuntu)
- Contain replicated virtual machines and storage (synchronized via direct Ethernet links between the two PMs)
- Support virtual machines running tested guest operating systems
For more information about the configuration of PMs in a ztC Edge system, see System Requirements Overview.
ztC Edge systems provide a secure out-of-box experience. You also have the option of implementing additional security-related configuration settings. For information, see Security.
