Deployment with high availability (HA) features

VM Recovery Manager DR

The IBM VM Recovery Manager DR for Power Systems include all the essential and advanced features of disaster recovery. For more information about the disaster recovery features of the VM Recovery Manager DR, see the Overview for IBM VM Recovery Manager DR for Power Systems section.

VM Recovery Manager HADR solution

The IBM VM Recovery Manager family provides high availability (HA) and disaster recovery (DR) solutions for virtual machines (VMs) within a site and across sites using a single orchestrator. In case of down time or planned outage, user can migrate a VM from one host (server) to another host within a home site (for partial failure) or backup site (for complete failure).

VM Recovery Manager HADR for Power Systems support different types of failure recovery within a site and across sites. Within a site, failures can occur at application level, VM level, or host level. In case of failures within a site, the VM migrates automatically. But if the failure is across sites, which includes planned and unplanned move operation at the site level and the host group level, you must initiate a move operation manually. VM Recovery Manager HADR uses shared storage pool (SSP) cluster formed within source site's Virtual I/O Server (VIOS) instances for VM, which also monitors a host to provide the high availability solution.

The important features of the VM Recovery Manager HADR includes all the essential and advanced features of disaster recovery and high availability features such as Live Partition Mobility (LPM), support for VM failure and host failure recovery, and application failover support within a home site, Fibre Channel (FC) adapter failure, network adapter failure, monitoring CPU and memory usage, move operation and failover rehearsal operation across the site along with all other DR features. The workgroup feature is not supported for the HADR type of deployment. For more information about the high availability features in the VM Recovery Manager DR, see High availability features.

VM Recovery Manager HADRHA

The high availability features are available within the site and supported both on home and backup sites for HADRHA type of configuration. For example, you can back up a failed virtual machine and restart a virtual machine within the same site, or move the failed virtual machine to other site. The failover operations for disaster recovery can be performed from one site to another site. The high availability features are available across sites, within the same site, and in the backup site. The workgroup feature is not supported for the HADRHA type of deployment.
