A method of determining compatibility of a virtual machine or virtual machine disk file with a host, including a storage host, is disclosed. A lookup matrix is created to provide a fast compatibility lookup for a group of computing objects and a group of hosts. To create the lookup matrix, computing object properties are retrieved from each of the plurality of computing objects. The computing object properties include resource requirements of each of the plurality of computing objects. Further, host properties are retrieved from each of the plurality of hosts. The method further includes creating a plurality of host logical groups of a subset of the plurality of hosts having substantially same host properties and creating a plurality of computing object logical groups of a subject of the plurality of computing objects having substantially same computing object properties. The lookup matrix provides answers whether each member of a selected computing object logical group can be transferred to each member of a selected host logical group.
