Proceedings of the NSSDC Conference on Mass Storage Systems and Technologies for Space and Earth Science Applications

The proceedings of the National Space Science Data Center Conference on Mass Storage Systems and Technologies for Space and Earth Science Applications held July 23 through 25, 1991 at the NASA/Goddard Space Flight Center are presented. The program includes a keynote address, invited technical papers, and selected technical presentations to provide a broad forum for the discussion of a number of important issues in the field of mass storage systems. Topics include magnetic disk and tape technologies, optical disk and tape, software storage and file management systems, and experiences with the use of a large, distributed storage system. The technical presentations describe integrated mass storage systems that are expected to be available commercially. Also included is a series of presentations from Federal Government organizations and research institutions covering their mass storage requirements for the 1990's

Database machines in support of very large databases

Software database management systems were developed in response to the needs of early data processing applications. Database machine research developed as a result of certain performance deficiencies of these software systems. This thesis discusses the history of database machines designed to improve the performance of database processing and focuses primarily on the Teradata DBC/1012, the only successfully marketed database machine that supports very large databases today. Also reviewed is the response of IBM to the performance needs of its database customers; this response has been in terms of improvements in both software and hardware support for database processing. In conclusion, an analysis is made of the future of database machines, in particular the DBC/1012, in light of recent IBM enhancements and its immense customer base

High Availability and Scalability of Mainframe Environments using System z and z/OS as example

Mainframe computers are the backbone of industrial and commercial computing, hosting the most relevant and critical data of businesses. One of the most important mainframe environments is IBM System z with the operating system z/OS. This book introduces mainframe technology of System z and z/OS with respect to high availability and scalability. It highlights their presence on different levels within the hardware and software stack to satisfy the needs for large IT organizations

System z and z/OS unique Characteristics

Many people still associate mainframes with obsolete technology. Surprisingly, the opposite is true. Mainframes feature many hardware, software, and system integration technologies, that are either not at all, or only in an elementary form, available on other server platforms. On the other hand, we know of no advanced server features which are not available on mainframes. This paper lists some 40 advanced mainframe technologies. There is a short description of each item together with a literature reference for more information

A technical study of charge back and monitoring systems in virtual environment

In the recent years the shared services concept has become an integral part of business. These shared services can be in the form of information technology, engineering and lot more. Service providers spent huge amounts of money to build an infrastructure that can provide efficient and valued services to the customers. In IT business these services varies from providing basic consultancy and managing the IT operations of the customers to running high priority business processes,(online banking). Customers of these services pay for these services, so a mechanism of resource usage metering is required to accurately charge the users and at the same time a monitoring mechanism is required to have a check on the services being provided to the customers for any resource contention and service degradation and future capacity planning. If a service provider is unable to develop an accurate charge back and monitoring mechanism then the equation of service provider and customer becomes a point of frustration for both sides. charge back and monitoring systems developed for physical environment are not capable to measure the resource usage in virtual environment because in virtual environment (Z/VM) resources are shared between users and it becomes difficult to measure the resource usage by a specific user. Until now a few tools have been developed that provides efficient resource metering and monitoring in virtual environment (Z/VM) but every business has its own requirements and system setup so mostly these tools need some customizations to fit into the business. This work mainly concentrated on what kind of resource utilization data is available on Z/VM and on LINUX guests running on Z/VM to effectively charge the customers running there guest Linux Operating systems in virtual environment (Z/VM based) and to monitor the cpu and memory utilization to check whether the estimate of memory allocation for linux guests running different applications made by system (PWSS) is a good estimate or require some optimizations. Because memory utilization is considered more expensive in virtual environment in the context of system performance. The study also includes a comparison between this technique of charge back and some commercial products from IBM and CA (Computer Associates) that provides charge back and monitoring facility in Z/VM based virtual environment, and provides some benefits of this work in the proposed environment.Master i nettverks- og systemadministrasjo

Goddard Conference on Mass Storage Systems and Technologies, volume 2

Papers and viewgraphs from the conference are presented. Discussion topics include the IEEE Mass Storage System Reference Model, data archiving standards, high-performance storage devices, magnetic and magneto-optic storage systems, magnetic and optical recording technologies, high-performance helical scan recording systems, and low end helical scan tape drives. Additional discussion topics addressed the evolution of the identifiable unit for processing (file, granule, data set, or some similar object) as data ingestion rates increase dramatically, and the present state of the art in mass storage technology
