MIVOICE BUSINESS RESILIENCY AND VMware vCENTER HIGH
AVAILABILITY
MiVoice Business Virtual offers inherent software resiliency with primary node failure detection
and automated failover to a secondary node, thereby offering users with highly available phone
service. Certain policies must be adhered to when using MiVoice Business Virtual resiliency.
For instance, anti-affinity rules should be established to ensure that the primary MiVoice
Business Virtual and secondary failover MiVoice Business Virtual are never started on the same
physical host server within a VMware cluster.
The anti-affinity rule to prevent the primary and secondary MiVoice Business Virtual from being
started on the same server is set in the DRS affinity rules. Simply created an affinity rule to
Separate Virtual Machine and specify the primary and secondary virtual machine name.
As part of vCenter, VMware offers VMware High Availability (HA) - a service that automatically
detects physical server failure or virtual machine failure, and restarts virtual machines on
alternate servers when a failure is detected. In the case of MiVoice Business Virtual, VMware
HA will detect a failure of the server that is hosting the MiVoice Business Virtual or the failure
of the virtual machine containing MiVoice Business. Upon failure, VMware HA will restart a new
instance of the MiVoice Business Virtual on an alternate server host. Standard VMware
configuration rules and certain policies must be adhered to. For example, shared storage
technology such as iSCSI, NFS or SAN must be available in the HA cluster.
Both MiVoice Business resiliency and VMware HA can be used at the same time. Figure 9
contrasts the various possible configurations and MiVoice Business availability levels that can
be obtained.
