Ensuring Hardware Redundancy in a Virtualized Environment

A computer system adapted to generate an Availability Management Framework (AMF) configuration in which service units of a service group are allocated to node groups and the node groups are allocated to physical nodes such that hardware redundancy for the service group is guaranteed, wherein each service unit is a unit of redundancy for services provided and protected by the service group, and each service unit includes one or more hardware components, software components, or a combination of hardware and software components, the computer system comprising:

• one or more processors;
• one or more memory devices coupled to the one or more processors;
• and
• a configuration generation module coupled to the one or more processors and the one or more memory devices, the configuration generation module adapted to:
• generate a node group set (NG set) of the node groups, wherein each node group includes a group of virtual machines and is to be mapped to a different host group that includes one or more physical nodes;
• generate collocation and separation rules for the virtual machines to specify which ones of the virtual machines are collocated in a same node group and which ones of the virtual machines are separated by different node groups;
• and
• map each service unit of the service group to a different node group in the NG set to thereby guarantee hardware separation in the AMF configuration for different service units of the service group and for the virtual machines allocated to the different service units.

A method, implemented by a computer system adapted to deploy an Availability Management Framework (AMF) configuration to a service provider system in which service units of a service group are allocated to node groups and the node groups are allocated to physical nodes such that hardware redundancy for the service group is guaranteed, wherein each service unit is a unit of redundancy for services provided and protected by the service group, and each service unit includes one or more hardware components, software components, or a combination of hardware and software components, the method comprising the steps of:

• forming a node group set (NG set) of the node groups according to the AMF configuration, wherein each node group includes a group of virtual machines and is to be mapped to a different host group that includes one or more physical nodes;
• applying collocation and separation rules to the virtual machines, the collocation and separation rules specify which ones of the virtual machines are collocated in a same node group and which ones of the virtual machines are separated by different node groups;
• and
• mapping each service unit of the service group to a different node group in the NG set according to the AMF configuration to thereby guarantee hardware separation for different service units of the service group and for the virtual machines allocated to the different service units.
