Definitions
- the present invention relates generally to automated cartridge systems (ACS) or automated library systems, and more specifically, to an improved ACS arrangement which eliminates user monopolization of a tape drive in the ACS system.
- ACS automated cartridge systems
- ACS automated cartridge systems
- the user whenever a user is performing a task which may require need of a storage/tape device, the user sends a request to a host computer control system. Upon receipt of such a request, the operating system must grab the storage device and allocate the device to the requesting user for the duration of the entire task irrespective of the amount of use actually made by the user.
- the present invention provides a virtual ACS and data storage device management method which incorporates a temporary data buffer arrangement between multiple user systems and any type of conventional physical data storage devices, wherein the temporary data buffer arrangement is arranged to emulate a physical data storage device when accessed by each of the user systems, while also allowing multiple users simultaneous access to read and write data to the temporary data buffer.
- the system includes a control processor arranged to periodically transfer any data in the temporary data buffer arrangement to one of the physical data storage devices.
- a virtual automated cartridge system including a data storage manager having a first input/output connected to at least one remote user computer system, and a second input/output connected to at least one physical data storage device, and an interim data storage device connected to the data storage manager and arranged to emulate a physical data storage with respect to storing or retrieving data for the at least one remote user computer system.
- the data storage manager includes a processor operative to assign a portion of the interim data storage device to a user computer system upon receipt of a user request for allocation of a data storage device for a duration of time .
- a method for efficiently managing allocation of at least one physical data storage device in an automated cartridge system to competing remote user computer systems includes providing an interim data storage device which is arranged to emulate a physical data storage with respect to storing or retrieving data for a remote user computer system, and assigning a first portion of the interim data storage device in lieu of the at least one physical data storage device upon receiving a request from a remote user computer system for allocation of a data storage device for a duration of time.
- FIG. 1 is a block diagram of data storage management system in accordance with the present invention.
- Figure 2 is a flow chart showing the virtual ACS process in accordance with the present invention.
- a data storage management system 10 having a plurality of user subsystems denoted for illustrative purposes as multiple virtual storage (MVS) type systems 12 and non-MVS type systems 14, each of which are conventional and well understood to one of ordinary skill in the art, connected to a storage manager 16 via respective data lines 18 and control lines 20.
- Storage manager 16 includes a suitable processor 22 programmed to provide the necessary control process to implement the "virtual" data storage of the present invention, and provides an intermediary data storage control point for a plurality of physical data storage devices represented as disk subsystems 24, tape subsystems 26, optical subsystems 28, and other types of data storage subsystems 30.
- storage manager 16 also includes an interim/temporary data buffer storage device 32 which is utilized by storage manager 16 as a virtual disk or tape device when access to a physical storage subsystem is requested by a user.
- a request for access to a physical storage subsystem may be a request for one of the subsystems 24-30 actually used in system 10, however this is not a requirement because the use of a virtual disk in lieu of an actual physical storage media in accordance with the present invention allows storage manager 16 to receive user requests for any type of storage subsystem whether connected to system 10 or not.
- Interim data buffer storage device 32 can be implemented as a high speed buffer arrangement, such as using solid state memory, DASD or any other suitable data storage arrangement capable of multiple, simultaneous user access.
- processor 22 determines that a request has been received from a user seeking allocation of a physical storage subsystem.
- processor 22 initially assigns at block 102 a portion of interim data buffer 32 for allocation to the requesting user.
- the allocated user Upon set up, the allocated user will believe an actual physical storage subsystem device has been reserved, and will proceed to read and write data as indicated by the particular application currently being executed as indicated at block 104.
- block 106 multiple users are queued and assigned different portions of interim data buffer 32.
- the assigned portions of interim data buffer 32 are arranged in accordance with known design principles to react like or emulate operation of a compatible data storage device, such as one of the actual physical data storage devices in subsystems 24- 30.
- the buffer is designed to emulate a storage device compatible with the user request as viewed by the remote user, compatibility between the remote user and the actual type or format of physical data storage device is not required.
- the present invention advantageously allows any type of physical storage device to be used or added as an upgrade to an existing system.
- the interim buffer management arrangement would be modified to include an appropriate translation arrangement to allow data to be transferred between the buffer and the actual type of storage device employed.
- all data of the virtual volume in the interim data buffer 32 associated with the file of interest is transferred to one of the storage subsystems in such situations as the end of a user's current allocation, a filling up of memory capability in buffer 32, or periodically as part of an overall housekeeping process.
- interim data after interim data has been transferred to one of the actual physical storage subsystems, such data can be later retrieved back into the interim buffer as a virtual volume when desired by the user.
- the storage manager 16 After retrieval, the storage manager 16 again causes the buffer to emulate the requested type of physical storage subsystem to make the retrieved data available to the user.
- the present invention advantageously provides the illusion of a compatible tape or cartridge device, while further providing significantly improved data management flexibility and efficiency in data storage device use.
