Publication number: 20210336809Abstract: The billing amount can be flexibly changed according to the resource amount and the value of the data processing resources in an API provider's system platform at the time that the API was provided. An API billing system has an API provider system platform and an API connection platform. In the API billing system, the API provider system platform is configured such that a storage apparatus or a storage controller which controls the storage apparatus, can be added to the device configuration in addition to the API server, and the API provider system platform executes processing of the API requested from the application with a processor which differs according to its device configuration, and the API connection platform calculates the API usage fee based on the specification and utilization history of each device included in the processor upon execution of the processing of the API.Type: ApplicationFiled: September 2, 2020Publication date: October 28, 2021Inventors: Tatsuya MAKIE, Hiroshi ARAKAWA, Masayasu ASANO

Patent number: 9723080Abstract: A storage apparatus includes a storage unit for storing data read/written by a host computer and provides the host computer with a storage area of the storage unit as one or more volumes. The storage management computer includes a first memory for storing task information including contents of an operation process performed on the storage apparatus, as well as a scheduled starting time and scheduled termination time of a process. In the case where first task information is stored in the first memory, when resources used in the process of second task information stored in the first memory are the same as resources used in the process of the first task information, the storage management computer computes times required for executing the first task information and the second task information, based on a time during which the processes of the first and second task information conflict with each other.Type: GrantFiled: March 5, 2015Date of Patent: August 1, 2017Assignee: HITACHI, LTD.Inventors: Tsukasa Shibayama, Yukinori Sakashita, Masayasu Asano

Patent number: 9442809Abstract: According to the present invention, it is possible to construct a backup configuration of a particular application data, without influencing data of another application. A management computer is coupled to a host computer on which an application operates, and to a storage apparatus that includes a plurality of volume groups each having one or more logical volumes. At least one of the logical volumes is allocated to the application. The management computer includes a volume group overlapping use determination part and a backup policy determination part. When the backup of the volume group to which one logical volume belongs is configured, the volume group overlapping use determination part determines whether there is another application that uses the volume group. The backup policy determination part determines whether there is set, for another volume group, backup policy information same as that set for the application.Type: GrantFiled: October 13, 2015Date of Patent: September 13, 2016Assignee: HITACHI, LTD.Inventors: Misako Irisawa, Nobuhiro Maki, Masayasu Asano, Wataru Okada

Patent number: 9395928Abstract: A management system is coupled to a storage system group including a scale-out storage system (a virtual storage system). The management system has storage management information, which includes information denoting, for each storage system, whether or not a storage system is a component of a virtual storage system. The management system, based on the storage management information, determines whether or not a first storage system is a component of a virtual storage system, and in a case where the result of this determination is affirmative, identifies, based on the storage management information, a second storage system, which is a storage system other than the virtual storage system that includes the first storage system, and allows a user to perform a specific operation only with respect to this second storage system.Type: GrantFiled: May 14, 2015Date of Patent: July 19, 2016Assignee: Hitachi, Ltd.Inventors: Kyoko Miwa, Junichi Hara, Masayasu Asano

Patent number: 9367265Abstract: In a storage system 1, a storage apparatus A having a first pool 1430 including segments as unit storage areas and a storage apparatus B having a second pool 1430 having the same configuration are communicably connected to each other. In the storage system, an external volume identifier is associated with a logical volume 1420 included in the first pool 1430, the external volume identifier being used by a controller 1500 in the storage apparatus B to identify and manage the logical volume 1420 as an external volume 1425 that is a virtual volume in the storage apparatus B. Moreover, a volume identifier 5110 of the logical volume 1420 included in the first pool 1430 is rewritten into the external volume identifier in order to enable the storage apparatus B to utilize the logical volume 1420 created from the first pool 1430.Type: GrantFiled: September 25, 2013Date of Patent: June 14, 2016Assignee: Hitachi, Ltd.Inventors: Yuki Naganuma, Hirokazu Ikeda, Nobuhiro Maki, Masayasu Asano, Shinichiro Kanno

Patent number: 9244616Abstract: A storage system manages a pool to which multiple VVOLs (virtual logical volumes conforming to thin provisioning) are associated, assigns a real area (RA) from any tier in an available tier pattern associated with a write-destination VVOL to a write-destination virtual area (VA), and carries out a reassignment process for migrating data inside this RA to an RA of a different tier than the tier having this RA based on the access status of the RA assigned to the VA. A management system assumes that a specified tier has been removed from the available tier pattern of a target VVOL, predicts the performance of the target VVOL and all the other VVOL associated with the pool to which the target VVOL is associated, determines whether or not there is a VVOL for which the predicted performance is lower than a required performance, and when such a VVOL does not exist, instructs the storage system to remove the specified tier from the available tier pattern of the target VVOL.Type: GrantFiled: March 24, 2015Date of Patent: January 26, 2016Assignee: Hitachi, Ltd.Inventors: Kyoko Miwa, Tsukasa Shibayama, Masayasu Asano

Patent number: 9189344Abstract: An embodiment of this invention is a storage management system including a processor and a storage device to manage a storage system having one or more copy functions. The processor locates data designated to determine a backup method. The storage device stores copy function management information on the one or more copy functions of the storage system. The processor refers to the copy function management information to ascertain the unit of copy operation of each of the one or more copy functions. The processor determines a candidate for a copy function of the storage system to be used to back up the designated data depending on the data configuration in a volume holding the designated data and the unit of copy operation of the candidate for the copy function.Type: GrantFiled: March 10, 2015Date of Patent: November 17, 2015Assignee: Hitachi, Ltd.Inventors: Misako Kono, Nobuhiro Maki, Masayasu Asano, Junichi Hara
