The Dell Validated Design for Retail Edge provides both business continuity and data loss prevention if a disaster occurs. By consolidating most inVia application services on our proven VxRail hyperconverged infrastructure (HCI), we provide a single dashboard for managing a successful disaster recovery (DR) solution. VxRail simplifies the infrastructure stack by allowing compute, network, and storage resources to be managed as a single, shared pool. It provides a simple, scale-out architecture, leveraging VMware vSphere and VMware vSAN to provide server virtualization and software-defined storage, with simplified deployment, upgrades, and maintenance through VxRail Manager.
Azure Stack HCI provides an integrated view of the cluster though its integration with Windows Admin Center (see Monitor Azure Stack HCI clusters from Windows Admin Center). Business continuity and data loss prevention functionality can be leveraged by using Azure Site Recovery. Maintenance and upgrades to the Azure Stack HCI operating system are installed using Windows Admin Center, System Center, or PowerShell. The Cluster-Aware Updating feature orchestrates installing of the updates on each server in the cluster so that ISV applications continue running during the upgrade. KVM provides multiple methods to interact with the cluster, using command-line with virsh or the user interface virt-manager.
Both options provide basic functionality to backup and restore guest VMs with the caveat that the guest VM must be shut down to do so. There are however third-parties offering disaster recovery solutions delivering failover and failback scenarios in real-time to restore workloads without any data loss.
