VirtualStorage Personal Computing VSPC was a service offered by IBM in the late 1970s and early 1980s ref In Germany, the service was announced in October, 1979 according to http www.computerwoche.de heftarchiv 1979 42 1194110 an article in Computerwoche dated 1979 10 19 . ref . From a data terminal, users could run both interactive processes and batch job s on remote computing hardware located in IBM service centres to which they were connected e.g. by telephone lines using modem s. Among the programming language s offered were VSPC variants of BASIC , FORTRAN , APL programming language APL and PL 1 . VSPC became obsolete following the invention of the Personal Computer as computing power became available to the individual user locally. In a campus setting, VSPC offered users the ability to create and submit programs to an IBM or compatible mainframe without using punched cards, though the programs were still submitted as card images, and programs so submitted needed all the usual IBM Job Control Language JCL statements to access the mainframe batch submission and resource allocation processes. Output from a job submitted through VSPC could be routed to a printer, or back to the user s VSPC account, though in general the output would be too wide to easily view on a VSPC terminal. Although IBM selectric terminals were supported with special typeballs for APL programming , most VSPC interaction was through half duplex IBM 3270 and compatible terminals. To use VSPC for APL programming, required a special terminal which implemented APL symbols in addition to the usual EBCDIC characters. References references Category IBM services ... more details

Rotary Storage Systems Rotary storage systems are filing cabinets specialised office furniture units usually consisting of a double sided rotating unit, allowing the user to access two full sides of filing from one point. A foot pedal or lever is often used to operate the rotation mechanism, thus allowing user easy control. Capacity, Siting and Speed Advantages Many rotary filing systems can store the contents of seventeen four drawer filing cabinets in just three eight tier units, allowing multiple times the storage volume created by traditional filing cabinets . A wide range of fitments makes the systems suitable for storing a vast array file types and multimedia. For security, each unit can invariably be locked individually. Rotary storage systems usually have no shutters or doors, thereby can be sitied very close to walls or partitioning, giving a very efficient use of floor space. Units are often used to divide office space. Rotary storage units can allow faster file access than banks of conventional cabinets as 50 of stored items are immediately visible to the operator, the rest typically being a pedal push away.

Unreferenced stub auto yes date December 2009 Stable storage is a classification of computer Computer data storage data storage technology that guarantees atomicity database systems atomicity for any given write operation and allows software to be written that is robustness computer science robust against some hardware and power failures. To be considered atomic, upon reading back a just written to portion of the disk, the storage subsystem must return either the write data or the data that was on that portion of the disk before the write operation. Most computer hard disk drive disk drives are not considered stable storage because they do not guarantee atomic write an error could be returned upon subsequent read of the disk where it was just written to in lieu of either the new or prior data. Implementation Multiple techniques have been developed to achieve the atomic property from weakly atomic devices such as disks. Writing data to a disk in two places in a specific way is one technique and can be done by application software . Most often though, stable storage functionality is achieved by Disk mirroring mirroring data on separate disks via RAID technology level 1 or greater . The RAID controller implements the disk writing computer algorithm algorithms that enable separate disks to act as stable storage. The RAID technique is robust against some single Hard disk failure disk failure in an array of disks whereas the software technique of writing to separate areas of the same disk only protects against some kinds of internal disk media failures such as bad Disk sector sectors in single disk arrangements.
