STORAGE SYSTEM AND STORAGE METHOD
First Claim
1. A storage system comprising:
- a first memory; and
a processor coupled to the first memory and the processor configured tocalculate a first number of accesses from a first server to the first memory and a second number of accesses from a second server to the first memory,detect switching from the first server to the second server in accordance with the first number and the second number,determine whether a first site in which the first memory is disposed and a second site in which the second server is disposed are different on the basis of location information that represents a location relationship between the first memory and the second server, andperform a change of an access destination of the second server to a second memory disposed in the second site when the first site and the second site are different.

Abstract
A storage system includes a first memory, and a processor configured to calculate a first number of accesses from a first server to the first memory and a second number of accesses from a second server to the first memory, detect switching from the first server to the second server in accordance with the first number and the second number, determine whether a first site in which the first memory is disposed and a second site in which the second server is disposed are different on the basis of location information that represents a location relationship between the first memory and the second server, and perform a change of an access destination of the second server to a second memory disposed in the second site when the first site and the second site are different.

6. A computer-implemented storage method comprising:
-
calculating a first number of accesses from a first server to a first memory and a second number of accesses from a second server to the first memory; detecting switching from the first server to the second server in accordance with the first number and the second number; determining whether a first site in which the first memory is disposed and a second site in which the second server is disposed are different on the basis of location information that represents a location relationship between the first memory and the second server; and changing an access destination of the second server to a second memory disposed in the second site when the first site and the second site are different. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory computer-readable medium storing instructions executable by one or more computer, the instructions comprising:
-
one or more instructions for calculating a first number of accesses from a first server to a first memory and a second number of accesses from a second server to the first memory; one or more instructions for detecting switching from the first server to the second server in accordance with the first number and the second number; one or more instructions for determining whether a first site in which the first memory is disposed and a second site in which the second server is disposed are different on the basis of location information that represents a location relationship between the first memory and the second server; and one or more instructions for changing an access destination of the second server to a second memory disposed in the second site when the first site and the second site are different.
