A method to more effectively and efficiently diagnose problems in a storage network is disclosed. In one embodiment, such a method includes generating, for a storage network, a resource map that identifies components therein. For each component in the resource map, the method identifies an importance factor that indicates the component's importance in the storage network. When a problem is detected in the storage network, the method identifies, for each component in the resource map, a potential cause factor that indicates how likely the component is to have caused the problem. The method also calculates, for each component in the resource map, a problem responsibility factor to indicate to what extent the component is held responsible for the problem. A corresponding system and computer program product are also disclosed.

Provided is a backflow cascade novel process for producing a lithium-7 isotope. The process comprises an upper backflow section, an extraction section, an enrichment section, a lower backflow section, and a product acquiring section. Upper backflow phase-conversion liquid and lower backflow phase-conversion liquid are respectively added to the upper backflow section and the lower backflow section, and upper backflow phase-conversion liquid and lower backflow phase-conversion liquid of the lithium material are controlled; the product is precisely acquired in the product acquiring section; an organic phase is added to the upper backflow section, and is recycled in the lower backflow section. By means of cascade connection with a high-performance liquid separator, environmental protection, high efficiency, and multi-level enrichment of the lithium-7 isotope are achieved, and a high-abundance lithium-7 isotope product is obtained.
