The MSS supports a large, networked, multivendor, Unix-based supercomputing facility. The MSS provides all processors on the network with the ability to store large amounts of data in a highly accessible long-term repository. Processors on this network vary in size and capability from personal computers and workstations to multiple large supercomputers like the CRAY-2 and CRAY Y-MP. The MSS emulates a Unix System V file system and is capable of storing hundreds of thousands of files ranging in size from a few bytes to 2 Gbytes. This use of Unix reduces the training requirements and allows the use of existing Unix networking solutions along with locally developed networking enhancements. The systems are currently networked via the NSC HYPERchannel and Ethernet. To assure data integrity and provide volume spanning capabilities, the IBM MVS operating system was integrated into the MSS. The MSS implementation was designed to make MVS transparent to the MSS user. >","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

The process of moving data to the MSS from foreign media, such as tapes, is called IMPORT. The reverse process is called EXPORT. The IMPORT/EXPORT software application was developed to move data to and from the MSS at NCAR (National Center for Atmospheric Research). This unique approach provides the user with many options as well as the flexibility to control data movement. Using the IMPORT/EXPORT program does not burden the user with a complex series of tape allocation requests for a one-step request. It was written to be easily upgradable to support many types of external storage devices. >","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

Keele","doi":"10.1117/12.944635","DOIUrl":"https://doi.org/10.1117/12.944635","url":null,"abstract":"The data storage hierarchy of IBM System/370 compatible mainframes can be augmented by a plug-compatible optical disk storage system. The storage hierarchy consists of main memory, rotating magnetic disk memory or Direct Access Storage Devices (DASD), magnetic tapes, and hardcopy. Only data stored on DASD is available for on-line processing. Data recorded on magnetic tape is generally off-line. Long time delays are generally associated with the transfer of data from the tape library. The need exists for a form of high-capacity on-line storage. Optical storage can satisfy this need, and by emulating 3480 cartridge tape subsystems, the benefits of Write-Once-Read-Many (WORM) optical disk storage can be made conveniently available to IBM and compatible mainframes. To accomplish this, a controller is required which attaches to IBM's I/O channel and emulates a 3480 tape control unit. The resulting optical mass storage system is compatible with IBM operating systems and applications software. Data is stored on the optical disk as a collection of virtual tapes. Virtual tapes can be retrieved from a selected optical disk and, after processing, the revised data can be written to unused sectors of the optical disk. The virtual tapes save the time expended in tape mount/demount operations. The optical disk system is able to interpret and act on mount/demount messages directly, providing fully automated operation. In a jukebox configuration, thousands of virtual tapes can be handled automatically with no operator intervention. The described optical storage system addresses a longstanding requirement for on-line access to large volumes of data. By emulating the IBM 3480 magnetic tape system and storing data as virtual tapes, it offers a practical solution to the need for access to terabytes of data.","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.
