Description

The present invention relates to a storage device, a management device, an information processing system, a control method and a program.

By storing data in the storage area (cache area) of the cache memory of the storage device, the response speed of the storage device is improved.

When the storage device does not store the requested data in the cache area, the storage device accesses the storage area of the disk device (hereinafter referred to as the disk area) whose access speed is lower than that of the cache memory, and the access requested data is obtained. To search for. However, as the frequency of access to the disk area and the number of accesses increase, the response speed of the storage device decreases.

Therefore, it is preferable that the storage device acquires the data requested to be accessed from the cache area. Further, the higher the rate of acquiring data from the cache area (cache hit rate), the higher the response speed of the storage device.

Patent Document 1 describes a technique for determining whether or not to retain user environment information in a cache memory according to a priority set for each user. Specifically, in the technique described in Patent Document 1, when the priority of the user satisfies a predetermined condition (high priority), the user environment information is held in the cache memory. On the other hand, in the technique described in Patent Document 1, when the priority of the user does not satisfy a predetermined condition (the priority is low), the user environment information is deleted from the cache memory. In Patent Document 1, the user environment information means information for realizing a virtual desktop environment for each user on a virtual PC (Personal Computer).

Patent Document 2 describes a technique of detecting a terminal based on the personal ID of the terminal user when detecting that the terminal user has passed through the door, and performing a predetermined operation on the terminal. ing. For example, in Patent Document 2, when it is detected that a terminal user has passed through a door, the terminal is detected based on the personal ID of the terminal user, and a working environment corresponding to the terminal user is provided to the terminal. The technology to build is illustrated.

The disclosure of the above prior art document shall be incorporated into this document by citation. The following analysis was made from the point of view of the present invention.

As described above, the higher the cache hit rate, the higher the response speed of the storage device.

However, even when the data for which access is requested is stored in the cache area, the storage device may execute a backup process, a restart process, or the like and overwrite the data stored in the cache area. After overwriting the data stored in the cache area, the storage device accesses the disk area and searches for the data. As a result, the response speed of the storage device is reduced.

For example, it is assumed that the storage device stores data that can be accessed by the user in a cache area during the business hours of the user. In that case, the storage device improves the response speed of the storage device during the business hours of the user.

However, when the storage device is scheduled to execute the backup process, the restart process, etc. outside the user's business hours (for example, at night), and the backup process, the restart process, etc. are executed based on the scheduling. There is. In that case, when the user starts the business the next day and requests the storage device to access the data, the storage device may access the disk area and search for the data. As a result, when the user starts the business, there is a possibility that an access delay and an increase in the processing load on the disk device may occur.

Therefore, assuming access to the disk area, measures such as improving the performance of the disk device and increasing the number of disk devices can be considered. However, taking measures such as improving the performance of the disk device and increasing the number of disk devices will increase the cost of the storage device.

That is, the file list generation unit 24 extracts the file name “file_A”, the file name “file_B”, and the file name “file_C” from the access log table shown in FIG.

In step S7, the file list transmission unit 25 writes the acquired file name as a look-ahead file list and transmits it to the storage device 3.

For example, it is assumed that the file list generation unit 24 has acquired the file name “file_A”, the file name “file_B”, and the file name “file_C”. In that case, the file list transmission unit 25 writes out the file name “file_A”, the file name “file_B”, and the file name “file_C” as a look-ahead file list, and transmits the file list to the storage device 3.

In step S8, the file list receiving unit 34 of the storage device 3 receives the look-ahead file list from the management device 2.

In step S9, the data writing unit 35 reads the data file having one or more file names included in the look-ahead file list from the disk area 32 and stores it in the cache area 33.

Next, the process of generating the access log will be described in detail.

FIG. 6 is a flowchart showing an example of the process of generating the access log.

In step S101, the storage device 3 detects access to the data file. Specifically, the storage device 3 detects access to a data file stored in at least one of the disk area 32 and the cache area 33.

In step S102, the access log generation unit 36 generates an access log in which the access date and time, the user name, and the file name are associated with each other.

In step S102, the access log transmission unit 37 transmits the generated access log to the management device 2.

In step S103, the access log receiving unit 23 of the management device 2 receives the access log from the storage device 3.

In step S104, the access log receiving unit 23 stores the received access log in the access log database 27.
