Storage area network management
Main Article Content
Abstract
The problems of effective management of tiered storage area network (SAN) are considered. The main independent variables and criteria for the operation SAN are defined. The criterion for selecting SAN management subsystem is proposed. The functional should covered with the SAN management subsystem is defined. Mathematical models for distribution users between SAN resources and management of tiered SAN resources are proposed. Genetic and heuristic algorithms for solving the problem of minimizing storage costs are proposed. The experimental results for different groups of tasks are given. It is shown that the genetic algorithm allows find a more effective solution than a heuristic algorithm. The average time spending on distribution of data depending on the dimension of the problem is estimated. The heuristic algorithm finds a solution faster than the genetic algorithm, but gives a less accurate result.
