Abstract: The present disclosure provides a method and apparatus for distributing an electric energy quantity. The method and apparatus are used for solving a problem that electric energy cannot be reasonably distributed among multiple household appliances in the related art. The method includes that a terminal detects a first remaining electric energy quantity of a photovoltaic panel; the terminal determines, according to pre-determined identification information of at least one household appliance to be electrified corresponding to each remaining electric energy quantity range of the photovoltaic panel, first identification information corresponding to a first remaining electric energy quantity range where the first remaining electric energy quantity is located; and the terminal controls the photovoltaic panel to electrify a first household appliance of the first identification information.

Abstract: A first storage device receives a first reservation preemption command from a host using a target port. The first reservation preemption command includes a port identifier of the target port, a to-be-checked reservation key, and a logical unit number (LUN). The first storage device encapsulates the to-be-checked reservation key, the LUN, the port identifier of the target port, and a port identifier of the forwarding port to obtain a second reservation preemption command. Further, the first storage device sends the second reservation preemption command to a second storage device using the forwarding port. The second storage device performs a reservation preemption operation based on the port identifier of the target port. When a split brain occurs in a host cluster, data consistency of different storage arrays can be ensured without relying on a Fiber Channel switch, thereby ensuring applicability in more scenarios.

Abstract: Embodiments of the present invention provide a method, system and server for delivering an advertisement based on user characteristic information. The method includes performing, by a server, data mining on user raw data corresponding to a client to obtain user characteristic information, generating a characteristic label based on the user characteristic information; determining, by the server, a type of advertisement according to the characteristic label, and delivering an advertisement of the type to the client. In the embodiments of the present invention, a great amount of user raw data is collected and stored in a server, data mining is performed on the user raw data, a characteristic label is generated based on user characteristic information obtained, and a network advertisement is delivered according to the characteristic label. Therefore, the advertisement can be delivered to particular users and the click ratio of the advertisement is increased.
