Abstract: A storage system includes one or more storage nodes each having a non-volatile storage device, a storage controller, and a volatile memory, in which the storage device includes a plurality of base image storage areas including at least a first base image storage area and a second base image storage area as areas for storing entire predetermined information stored in the memory as a base image, and the storage controller starts processing to store a next base image in the second base image storage area when the base image storage with respect to the first base image storage area is complete, and reads out the storage-completed base image and restores the image to the memory in a case where the predetermined information is lost from the memory.

Abstract: A policy determination apparatus according to a first aspect of the present invention includes an evaluation unit and a policy determination unit. The evaluation unit evaluates candidates of routing destinations to which a routing control apparatus routes requests, based on time-series data of types of metrics and priorities assigned to the types of metrics to generate routing destination evaluation data, where the types of metrics is generated based on monitoring data relating to the states of facilities on a network and are associated with the candidates. The policy determination unit determines a policy that the routing control apparatus uses for control of the routing destinations after the routing destination evaluation data is generated.

Abstract: According to one embodiment, a policy determination apparatus includes a policy determination unit, a change condition determination unit, and a change request unit. The policy determination unit determines a first policy that the first routing control apparatus uses for controlling a routing destination of a request including first destination data. The change condition determination unit determines, based on the monitoring data, whether or not a predetermined policy change condition is satisfied. When it is determined that the policy change condition is satisfied, the change request unit requests the first policy determination apparatus to change a second policy.

Abstract: An object is to provide an environmentally benign metal member having excellent corrosion resistance which exhibits a long-lasting corrosion resistance effect even in a saltwater environment or the like in which a water current is present, without requiring an external factor such as ultraviolet light. Provided is a metal member having excellent corrosion resistance in which at least a surface is made of an aluminum-based metal, the metal member comprising a corrosion protection film containing a poorly water-soluble lithium compound on the surface or a solid material containing a poorly water-soluble lithium compound on the surface.

Abstract: In order to allow vertical ventilation in a plurality of circumferential locations around the contour surface of a mold in the process of molding and regulate the temperature, the ventilation is carried out using an abutting path formed between the abutting surfaces of inner and outer members forming the contour surface part and its outer peripheral part of the mold, thereby achieving cooling. In this way, various shapes based on the axially changing shape of the contour surface are obtained readily and inexpensively, and temperature control suitable for the axially changing shape of the contour surface is carried out with high cooling effect.
