Abstract

An approach for allocating resources to an apparatus generally involves a resource allocator receiving a request that specifies one or more characteristics for the apparatus. A resource allocator determines the logical devices to be included in the apparatus so that the apparatus has the specified characteristics. For at least one logical device, the resource allocator determines whether a physical device is available that corresponds to the logical device. If a physical device is available, the resource allocator allocates the physical device to the apparatus. If a physical device is not available, the resource allocator does not allocate the physical device to the apparatus.
