Topics you need to know before using WinCC OA.
Virtual Environment Support
WinCC OA is used in very diverse computing environments, some of which are easier managed with the use of a enterprise virtualization software. Due to the good encapsulation and platform independence of WinCC OA, the use on a wide range of current versions of the most common virtualization products is possible. Our extensive, automated tests are provided via Proxmox and VMware (vSphere). In addition, Nutanix AHV is supported.
Nutanix AHV
Nutanix AHV (Acropolis Hypervisor) is an enterprise-grade hypervisor built on open-source KVM technology, delivered as part of the Nutanix hyper-converged infrastructure (HCI) platform.

Nutanix AHV

Nutanix AHV (Acropolis Hypervisor) is an enterprise-grade hypervisor built on open-source KVM technology, delivered as part of the Nutanix hyper-converged infrastructure (HCI) platform.

Nutanix AHV integrates computing-, storage-, and networking resources in a single platform managed through the Nutanix Prism management interface.

Key features of Nutanix AHV include:

KVM-based Virtualization: Built on open-source KVM for reliable and efficient full virtualization.
High Availability: Built-in VM high availability with automatic restart on node failure.
Centralized Management: Unified management of VMs, storage, and networking through the Prism web interface.
Multi-Node Clustering: Scalable cluster management across multiple Nutanix nodes for resource sharing and high availability.

Nutanix AHV provides an enterprise-grade virtualization platform suitable for production deployments of WinCC OA.

Notes and Restrictions

WinCC OA must be properly shut down before a Virtual Machine is stopped.
An "online backup" ("snapshot") of a Virtual Machine is not supported.
A snapshot of a virtual machine cannot be restored.
The clock of the virtual machine must never make an unexpected jump (forward or backward) while WinCC OA is running.
Redundant WinCC OA systems shall run on physically redundant hardware and network configurations.
