System and method for assigning storage in a storage network in accordance with stored management information

Abstract

An assigning system and an assigning method are provided for assigning a storage device or a unitary logical unit of the storage device. A VLU-LU correspondence table is provided which shows a correspondence between virtual logical units (VLU) virtually set in a host computer and logical units (LU) of a plurality of storage devices connected to a network. This table stores evaluation items of each storage device such as a delay time and an access frequency. An evaluation unit calculates an evaluation value of each evaluation item in the table, and a unitary logical unit of the storage is assigned in accordance with the evaluation value.

1 . An information processing system including a computer and a plurality of storages connected to a network, the computer comprising: 
 a store unit which stores features and information of storage areas corresponding to each the features; and    a processor unit which shows the features on a display of the computer, and changes evaluation determining information in accordance with one of the features selected by a user.    
   
   
       2 . An information processing system according to  claim 1 , wherein the information of the storage areas includes at least a capacity, and delay time, respectively of the storage having predetermined storage areas.  
   
   
       3 . An information processing system according to  claim 1 , wherein the processor calculates an evaluation value of each of the storage areas and displays the calculated evaluation value on the display of the computer.  
   
   
       4 . An information processing system including a computer and a plurality of storages connected to a network, the computer comprising: 
 a store unit which stores features and information of storage areas corresponding to each of the features; and    a processor which manages a plurality of first logical volumes and a plurality of second logical volumes, and assigns at least one second logical volume to one of the plurality of first logical volumes based on one of the features selected by a user.    
   
   
       5 . An information processing system according to  claim 4 , wherein each of the plurality of second logical volumes is a predetermined storage area unit.  
   
   
       6 . An information processing system according to  claim 4 , wherein the processor displays a relationship between the first logical volumes and the second logical volumes.
