1. A method for managing an information system comprising a storage system, a computer, and a management system, wherein the storage system comprises:
a storage controller; and a first memory device and a second memory device, each including a memory controller and a memory chip,
wherein the memory chip stores data into a plurality of memory units in the memory chip, and receives a data reading operation, a data writing operation, and a data deletion operation, and the data writing operation or the data deletion operation effects a failure of the memory units comparing to the data reading operation,wherein the memory controller manages unfailed memory unit storing data to be transferred to the storage controller and other unfailed memory unit as surplus memory units, stores update data transferred from the storage controller to a certain unfailed memory unit managed as the surplus memory unit, and manages the certain unfailed memory unit as the providing memory unit, the method comprising a step of:
(1) defining a plurality of logical components based on the memory memory device with storing relations between the first and second memory devices and the first and second logical components;(2) managing a first logical component from the logical components, associated with the first memory device of which the surplus memory units satisfies a condition;(3) managing a second logical component from the logical components, associated with the second memory device of which the surplus memory units does not satisfies the condition, as less appropriate for high frequency update than the first logical component. |
