In accordance with embodiments, an optimal location with the storage system is determined in response to receiving an indication that a storage object is to be created within the storage system. The system and method prioritize physical storage resources in which to create the storage object, prioritize components to be provided access to the created storage object, and prioritize the interface between the physical storage resources and the accessing component. The storage object is optimally created within the storage system based on the priorities and based, at least in part, on other created storage objects. ## Claims ### Claim 1 A method for providing an optimal network interface for a storage object comprising one or more physical storage resources, said method comprising: accepting under control of a processor a service level requirement for creating said storage object from said one or more physical storage resources;
