On a dual-node ztC Edge system, Stratus Redundant Linux software provides two user-defined availability levels for VMs: High Availability (HA) and Fault Tolerant (FT).
In HA operation, Stratus Redundant Linux automatically detects, isolates, and handles most hardware faults, thereby keeping your applications running. With HA remote-support technology, the software notifies the Stratus support center of various issues, indicating the type of fault and its exact location. This combination of automatic fault detection, isolation, and remote-support technologies ensures speedy access to expert support technicians and rapid problem resolution.
You select a VM’s availability level when you create or import the VM by using the ztC Console.
HA is suitable for applications that can tolerate occasional interruptions of a few minutes.
(The supported VM availability levels depend upon the system model, as listed in Virtual Machine Recommendations and Limits.)
