企业存储网格中资源请求任务的模拟与分析

Simulation and analysis of resource request task in enterprise storage grid

企业存储网格就是将特定企业范围内物理分布的各类存储系统和设备虚拟成单一的存储系统。在一个时间间隔内企业存储网格系统中发出的存储资源请求任务到达规律服从泊松流,可以多次生成服从泊松分布的随机数列来模拟存储资源任务的到达,通过插值和拟合,可得到相应的存储资源请求任务到达曲线,从而有利于了解网格系统中存储资源使用的忙闲状况,以便更充分利用存储网格中的资源。

Enterprise storage grid is to the enterprise-wide distribution of different storage systems and equipment as a single virtual storage system.In a time interval the arrival of storage resource requests task in the enterprise storage grid is similar to Poisson distribution,it can generate a random number sequence of Poisson distribution to simulate the arrival of the task of storage resources.By interpolation and fitting,the curve of storage resource request task arrival can be available.Thus facilitating the understanding of storage resources in the grid system busy conditions,to more fully use the resources stored in the grid.
