MyQ VMHA (Virtual Machine High Availability) license when installing MyQ on a Virtual Machine
Posted by MatjažS Admin on 27 February 2014 09:15 AM

Do I always have to buy a MyQ VMHA (Virtual Machine High Availability) license when installing MyQ on a Virtual Machine?

Basically the MyQ installed on a “normal” Virtual Machine behaves like installed on a “standard” PC/Server as long the VM is not transferred to another hardware machine.

For your better understanding I like to mention that the VMHA license will remove some Hardware related restriction when licensing a MyQ environment. 

Therefore the following are reasons to make use of the MyQ VMHA license:
1. Installing MyQ on a Cluster Server for high availability reason (MyQ Easy Cluster or Microsoft Cluster)
a. In case of failure of the MyQ Server another HW Server called Node will take over the operation from the original “Master” Server. 
When using MyQ standard licensing the MyQ licenses will immediately stop working when recognizing a different Hardware footprint when the system will swap operation from the Master Server to the Node. 
b. VMHA License will enable swapping to a new Hardware without creating a MyQ license issue.

2. Installing MyQ on a VM hosted at a service provider 
a. Even the VM hosted at a service provider is not setup as a Cluster server the hosting provider very often swap VM’s without prior notification from one physical hardware to another physical hardware. This happens most the time over night and the reason is that:
i. The Hardware hosting customers VM is not exclusive for one customer
ii. In case two or more customer “over-utilise” the physical hardware the providers shift a VM to another physical hardware which has more resources left to balance utilisation 
iii. This is done by an automated load balancing process so that may happen more frequently
b. Once again the MyQ VMHA license will enable swapping to a new Hardware without creating a MyQ license issue.
