Controlling virtual machine density and placement distribution in a converged infrastructure resource pool

1. A method, comprising:

identifying physical resources in a computer environment;

allocating virtual resources to the physical resources;

aggregating the virtual resources, as a virtual resource pool, at a per virtual machine level in the computer environment, wherein the virtual resource pool includes a total number of virtual resources assigned per virtual machine, wherein aggregating the virtual resources further comprises aggregating a number of virtual machines per load-balancer and aggregating a number of virtual machines per firewall;

evaluating the virtual resources in the virtual resource pool against resource pool domain constraints, wherein the resource pool domain constraints comprise a maximum size of a hypervisor domain, a Layer 2 network adjacency domain size, a maximum available storage input/output operations per second value, a maximum inter-switch link hops value, a maximum number of virtual LANs, and a maximum number of virtual SANs; and

determining a resource allocation adjustment as a function of the evaluating; and

adjusting the virtual resources based on the resource allocation adjustment to a desired level of computing performance based on quantifiable performance objectives, wherein the desired level of computing performance is a maximum specified virtual machine density.

2. The method of claim 1 , wherein the allocating the virtual resources to the physical resources includes allocating at least one of:

virtual CPUs per each physical core;

virtual memory per available memory of each physical node;

virtual network interface cards per each physical network interface card;

virtual switch ports per each physical port; and

available virtual storage associated with available physical storage.

3. The method of claim 1 , wherein the virtual resource pool further includes a total number of virtual resources assigned per virtual machine, the assigned virtual resources including at least one of:

virtual CPUs;

virtual memory;

virtual network interface cards;

virtual storage; and

virtual machines per virtual SAN.

4. The method of claim 1 , wherein the resource pool domain constraints include at least one of:

maximum size of a hypervisor domain;

Layer 2 network adjacency domain size;

maximum available storage input/output operations per second;

maximum inter-switch link hops; and

maximum virtual LANs and virtual SANs.

5. The method of claim 1 , wherein the resource allocation adjustment includes adding a new virtual machine.

6. The method of claim 1 , wherein the resource allocation adjustment includes reclaiming an existing virtual machine.
