A snapshot virtual device (SS-VDEV) is prepared for each snapshot family (SS-Family) and a deduplication virtual device is prepared apart from the SS-VDEV. When the same data is in a plurality of VOLs of the SS-Family, a storage system maps a plurality of addresses of the same data among the plurality of VOLs to address of the SS-VDEVs of the SS-Family. When duplicated data is in two or more SS-VDEVs, the storage system maps two or more addresses of the duplicated data of the two or more SS-VDEVs to addresses corresponding to the duplicated data among the deduplication virtual devices.

Storage system and storage control method of data deduplication between virtual devices

The functions of a mainframe environment are expanded by leveraging the functions of an open environment. A second storage of an open system externally connected to a first storage of a mainframe system comprises a second main volume of an open environment generated in association with a main logical device of the second storage, and a second sub volume of an open environment generated in association with a sub logical device of the second storage; the first storage comprises a first main volume of a mainframe environment generated in association with the main logical device of the second storage, and a first sub volume of a mainframe environment generated in association with the sub logical device of the second storage; when the first storage receives a data processing request from a host, the first storage reflects the processing request in the second storage and completes the processing; and when the first storage receives an execution request of a prescribed function, the first storage causes the second storage to execute the function.

Storage system and data processing method

Provided is a backup system including a storage system and a backup server, in which the backup server includes a ledger for managing a copy number and a backup acquisition date and time for each backup image, a data volume that stores data accessed by a business server, a backup image volume that stores a plurality of backup images at different time points of the data volume, an access volume having a volume ID for accessing the backup image from the backup server, and a data protection area including at least one volume having an internal volume ID instead of the volume ID for accessing from the backup server are configured in the storage system, and the backup image stored in the data protection area and the access volume are associated, and the backup image in the data protection area is provided to the backup server.

Backup system including a data protection area and a read-only volume used by a controller to read a copy of backup data from the data protection area

Backup data equivalent to the maximum number of generations to be held can be secured even when backup data is locked. When locking of prohibiting overwrite of one or more storage areas is performed, a backup server prepares a new backup management table and uses the backup management table and an archive management table, which is the past backup management table, to store the backup data equivalent to the maximum number of generations to be held into a storage system.

Security system, host system, and backup method

A storage controller configures a plurality of logical volumes, a CDP meta volume that manages history information related to writing from a server system for the logical volumes, and a CDP data volume that stores data of the plurality of logical volumes. The storage controller searches for, if a restoration request including a restoration time is received, the restoration request having one of the plurality of volumes as a restoration target volume, history information of the restoration target volume from the CDP meta volume, copies, in a case in which an evacuation time of old data included in the searched history information of the restoration target volume is newer than the restoration time, an SEQ number of the searched history information as first restoration control information, and acquires old history information on the basis of a previous SEQ number of the restoration target volume from the CDP meta volume.

Compounds of formula (I) defined herein are useful as a dopamine D1 receptor positive allosteric modulators (D1 PAM) and can be used as an active ingredient of a pharmaceutical composition for preventing and/or treating cognitive impairment, schizophrenia negative symptom, CIAS, Parkinson's disease, Alzheimer's disease, Huntington's disease, depression, ADHD, drug dependency, or the like.

Imidazodiazepine compound

The access from a host computer to a storage system is continued before and after data migration in the storage system. A first controller allocates a first logical storage area to a specific virtual storage area, stores first association information indicating the specific virtual storage area and the first logical storage area, and sends the first association information to the host computer. The first controller and the second controller perform data migration from the first logical storage area to a second logical storage area. The first controller releases the first logical storage area from the specific virtual storage area and reflects the release in the first association information. The second controller allocates the second logical storage area to the specific virtual storage area, stores second association information indicating the specific virtual storage area and the second logical storage area, and sends the second association information to the host computer.

Storage system, storage control method, and computer system

The present invention provides the function of dynamically switching the allocation of snapshot data in a pool according to the use status of the pool. More specifically, the present invention provides the function of dynamically switching a storage mode to be applied to the pool from a storage mode in which the snapshot data is aggregated in a specific pool volume to a storage mode in which the snapshot data is distributed to plural pool volumes, or from the storage mode in which the snapshot data is distributed to the plural pool volumes to the storage mode in which the snapshot data is aggregated in the specific pool volume, according to the use status of the pool.

Storage device and method for controlling the same

[Problem] To provide a compound useful as medicine having PDE4B inhibitory activity, in particular, as an active ingredient of a composition for treating or preventing schizophrenia, Alzheimer's disease, dementia, depression and the like. [Measures for Solution] The present inventors examined compounds having PDE4B inhibitory activity and found that a tricyclic or tetracyclic imidazo[1,2-a]pyridine derivative or salts thereof had a superior PDE4B inhibitory activity, thereby completing the present invention. The imidazo[1,2-a]pyridine derivative can be used as an agent for treating or preventing schizophrenia, Alzheimer's disease, dementia, depression and the like.

Imidazo[1,2-a]pyridine derivative

To provide a compound which has an excellent activity to modulate the functions of CCR4 or TARC and/or MDC and can be used for the prevention and/or treatment of various inflammatory diseases, allergic diseases, autoimmune diseases and the like. An acylaminopiperidine compound represented by the formula (I) or a pharmaceutically acceptable salt thereof. [Symbols in the formula represent the following meanings; A: a single bond or C-Calkylene, R: phenyl which may be substituted, etc., R: &#x2014;H or C-Calkyl, R: &#x2014;H, C-Calkyl or C-Ccycloalkyl, R: pyrrolidin-2-yl which may be substituted, etc., and D: benzene ring or pyrazole ring].
