8 results about "Server system" patented technology

The invention discloses a method for prolonging the service life of a server power supply and belongs to the field of computer technology. The method comprises the steps that firstly, an FW determines how many power modules should be switched on at the same time according to the power consumption of a server system, and other power modules are switched off; secondly, the FW numbers all the power modules and maintains two queues which are the running queue and the rest queue, when alternate switching is needed, one or more power modules are selected from the rest queue to be placed in the running queue and are switched on, and power modules in the same number are selected from the running queue to be placed in the rest queue and are switched off; finally, the FW conducts on-off operation on the power modules every once in a while alternately. Compared with the prior art, the method has the advantages that the service life of the power supply can be prolonged, the failure rate of the power supply can be reduced, and then operation and maintenance cost can be reduced for customers.

A client (i) adapted for updating individual elements (rij) of a client-item matrix (R) by means of Collaborative Filtering, R = XTY. The matrix (R) comprises a plurality of individual elements (rij),each individual element relating to a specific client (i) and a specific item (j). The client (i) utilizes an individual part (Ai) of a first model component (A) and at least one element of local client data (ui). The first model component (A) is a factor matrix A = X(i, k) comprising a plurality of client factor vectors (xi). The individual part (Ai) of the first model component (A) is the client factor vector (xi) for said client (i). The client (i) is connected to a server utilizing a second model component (B) and a global set of items (j1,..., jM). The second model component (B) is a factor matrix B = Y(J, k) comprising a plurality of item factor vectors (yj). The client (i) is configured to assign the individual part (Ai) of the first model component (A) to the client (i) and download a second model component (B) from the server. Thereafter, an updated individual part (Ai2) of the first model component (A) is calculated, as well as an individual value for each item (j1,..., jM).An evaluation of the value is uploaded to the server such that an updated second model component (B2) is calculated by the server. The updated second model component (B2) is downloaded from the server, and a new updated individual part (Ai3) of the first model component (A) is calculated.
