vMotion allows you to move an existing virtual machine from one virtual server platform to another with minimal interruption to the operation of the virtual machine. For example, this may be necessary if the existing server platform resources become exhausted.
For IP Office virtual machines, using vMotion allows you to move the virtual machine without changing its System Identification and requiring new IP Office licenses. If the virtual machine is running one-X Portal, any existing sessions may have to log in again after the move.
To use vMotion:
Each server platform requires 2 Gigabit Ethernet ports with one port dedicated to vMotion traffic.
The server platform CPUs must be similar, that is, from the same manufacturer and using similar processor architectures.
The Ethernet switch connecting the two servers must be minimum 10Gbps.
vMotion imposes specific storage requirements. Several options exist including iSCSI and local storage, among others. See VMware vMotion documentation for detailed requirements.
To decrease chances of one-X Portal connectivity interruptions, it is recommended that vMotion operation is done at times of low IP Office use.
