Data storage method, device and system and management server

InactiveUS20100268908A1Increase load on and instabilityLow utilization ratioError detection/correctionMemory adressing/allocation/relocationInstabilityResource utilization
The present invention relates to a data storage method, device and system and a management server. The data storage method includes: constituting a data pool from all of n data storage devices; when there is data for storage, polling all the devices in the data pool to select a group of m devices, and storing the data onto each of the selected group of m devices, where m is larger than one and smaller than n. The embodiments of the invention can address the problems of an existing data storage approach that a failing node causes an increased load on and instability of another node and that each node in the existing data storage approach has a low utilization ratio and poor predictability, so as to achieve uniform loads on the devices and high reliability of the nodes despite any failing node and improve the resource utilization ratio and predictability of the nodes.

Distributed type dynamic cache expanding method and system supporting load balancing

The invention discloses a distributed type dynamic cache expanding method and system supporting load balancing, which belong to the technical field of software. The method comprises steps of: 1) monitoring respective resource utilization rate at regular intervals by each cache server; 2) calculating respective weighing load value Li according to the current monitored resource utilization rate, and sending the weighting load value Li to a cache clustering manager by each cache server; 3) calculating current average load value of a distributed cache system by the cache clustering manager according to the weighting load value Li, and executing expansion operation when the current average load value is higher than a threshold thremax; and executing shrink operation when the current average load value is lower than a set threshold thremin. The system comprises the cache servers, a cache client side and the cache clustering manager, wherein the cache servers are connected with the cache client side and the cache clustering manager through the network. The invention ensures the uniform distribution of the network flow among the cache nodes, optimizes the utilization rate of system resources, and solves the problems of ensuring data consistency and continuous availability of services.

Method and device for measuring CSI (Channel State Information) as well as reference signal sending method and device

The invention provides a method and a device for measuring CSI (Channel State Information) as well as a reference signal sending method and a reference signal sending device. The method comprises the following steps: receiving reference signal allocation information sent by sending equipment and allocated reference signals of N reference signal ports; measuring CSI on the basis of the allocated reference signals of the N reference signal ports, wherein N is greater than or equal to 6, and the N reference signal ports consist of M groups of reference signal ports, wherein M is greater than or equal to 1. The step of measuring the CSI on the basis of the reference signals of the N reference signal ports comprises the following steps: measuring the CSI of the reference signals of each group of ports among the M groups of reference signal ports so as to obtain M first precoding matrixes, namely Wi, wherein i is equal to 1,2,...,M; obtaining a second precoding matrix W: W=W1*W2*...*WM according to the first precoding matrixes; obtaining a CQI (Channel Quality Indicator) according to the second precoding matrix. According to the scheme, measurement on the CSI is realized.
