Problems solved by technology

[0011] However, in existing storage systems where normal volumes and virtual volumes coexist, various information related to volumes are not displayed separately for normal volumes and virtual volumes, making it impossible to make appropriate judgments when selecting data migration destinations, for example. The problem of poor usability

Embodiment Construction

[0052] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0053] (1) Configuration of the storage system of this embodiment

[0054] In FIG. 1 , 1 as a whole denotes the storage system of the present embodiment. In this storage system 1, an internal storage device 4 is connected to a business host 2 through a first network 3 composed of a SAN (Storage Area Network) or the like, and a plurality of external storage devices are connected to the internal storage device 4 5. In addition, the business host 2, the first network 3, the internal storage device 4, and each external storage device 5 are connected to the management server 7 through a second network 6 composed of, for example, a LAN (Local Area Network).

[0055] The business host 2 is a computer device that executes various business application programs, and has hardware resources such as a CPU (Central Processing Unit) and a memory. Various pr...

Abstract

A management device (7) and management method capable of improving usability of a storage system is proposed. The management device and the management method are for managing data migration between volumes in a storage system (1) in which normal volumes to which fixed storage areas are allocated in advance and virtual volumes to which storage areas are dynamically allocated according to use status coexist as types of volumes for reading and writing data and are arranged so that information regarding each volume is collected, and based on the collected information, at least a total logical capacity (30B) that is a summation of logical capacities determined in advance for the respective volume is separately displayed for normal volumes and virtual volumes.

Description

technical field [0001] The present invention relates to a management device and a management method, and is applicable to, for example, a storage system. Background technique [0002] Conventionally, a user of a storage system calculates a fixed logical capacity of a volume to be used by the user, and creates and uses a volume to which a storage area of ​​the logical capacity size is allocated. Therefore, even if it is not used initially, it is necessary to prepare a storage device with a logical capacity in anticipation of future business changes. Hereinafter, a volume to which a fixed amount of storage area is allocated in advance is referred to as a normal volume. [0003] In contrast, in recent years, a virtualized volume function has been proposed as one of functions of storage devices. The virtual volume function is a function in which the user presents a virtual volume (hereinafter referred to as a virtual volume) to the host device as a volume for reading and writi...
