Server virtualization platforms like Oracle Linux Virtualization Manager offer a number of advanced features including Live Migration and VM high availability to ensure that applications continue running in your data center. However, if your data center loses power or is taken offline due to a natural disaster, these advanced features will not work without the compute, storage, or networking infrastructure to run your applications. The high availability features protect against individual component failures; but Disaster Recovery capabilities are required to protect against site-wide outages.
Oracle Linux Virtualization Manager 4.3 now supports Disaster Recovery features to connect multiple data centers and further protect your critical business applications. The Disaster Recovery features can be used in either an active-active configuration or an active-passive configuration to keep applications available to your end users even when a disaster might strike your data center. Oracle has fully tested the Disaster Recovery solutions based on the open source oVirt project and offers them as a feature of Oracle Linux Virtualization Manager.
Disaster Recovery features supported by Oracle Linux Virtualization Manager include:
Active-Active Disaster Recovery: Active-active disaster recovery uses a stretch cluster configuration. This means that there is a single Oracle Linux Virtualization Manager environment with a cluster that contains hosts capable of running the required virtual machines in the primary and secondary site. The virtual machines in the primary site can automatically migrate to hosts in the secondary site if an outage occurs.
Active-Passive Disaster Recovery: Active-passive disaster recovery is a site-to-site failover solution. Two separate Oracle Linux Virtualization Manager environments are configured: the active primary environment and the passive secondary (backup) environment. With active-passive disaster recovery, you must manually execute failover and failback (when needed) both of which are performed using Ansible playbooks.
The latest Oracle Linux Virtualization Manager 4.3.10 errata release also includes:
Bug fixes and security updates: A number of RPMs have been updated to incorporate bug fixes and security patches.
More information on these updates can be found in the Release Notes and the Administration Guide located in the Oracle Linux Virtualization Manager Document Library.
Customers that have already deployed Oracle Linux Virtualization Manager 4.3 can update to the latest 4.3.10 updates using the Oracle Linux yum server or the Oracle Unbreakable Linux Network. Users will access the oVirt 4.3 channel and execute a couple of commands:
# yum update ovirt\*setup\*
New deployments of Oracle Linux Virtualization Manager can also be done using the same oVirt43 yum channels. For new Oracle Linux KVM host deployments, installation media (ISO images) are available from the Oracle Linux yum server. Additional information on updating, upgrading, or installing Oracle Linux Virtualization Manager and KVM hosts can be found in the Getting Started Guide.
Both Oracle Linux Virtualization Manager and Oracle Linux can be downloaded, used, and distributed free of charge and all updates and errata are freely available.
The Oracle Linux Virtualization Manager Disaster Recovery solution can be easily deployed to configure, monitor, manage, and maintain service uptime for an Oracle Linux KVM environment with enterprise-grade performance and support from Oracle. Support for Oracle Linux Virtualization Manager is available to customers with an Oracle Linux Premier Support subscription. Refer to Oracle Linux Support for information about Oracle Linux support levels.
