The focus is on satisfying the performance requirements of a large-scale storage system. A number of kernel modifications and additions were made to overcome a number of Unix kernel deficiencies. These deficiencies included the lack of a lightweight tasking facility in the kernel, process-blocked I/O (input/output), inefficient data copies between user and system space, and the lack of optimized drivers for leading-edge storage devices. >","PeriodicalId":282025,"journal":{"name":"[1990] Digest of papers.

Campbell","doi":"10.1109/MASS.1990.113571","DOIUrl":"https://doi.org/10.1109/MASS.1990.113571","url":null,"abstract":"Results of a demonstration prototype semantic data model (SDM) using the expert system development tool NEXPERT OBJECT are presented. In the prototype, a simple instance of an SDM was created to support a small part of a hypothetical application for the earth observing system data information system (EOSDIS). The massive amounts data that EOSDIS will generate require the definition and design of a powerful information-management system in order to support even the most basic needs of the project. In this effort, the application domain is characterized by a semantic-like network that represents the data content and the relationships between the data considering both user views and a more generalized domain architectural view of the information world. The data in the domain are represented by objects that define classes, types, and instances of the data. In addition, data properties are selectively inherited between parent and daughter relationships in the domain. Based on the SDM, a simple information system design is developed from the low-level data-storage media, through record management and metadata management, to the user interface. >","PeriodicalId":282025,"journal":{"name":"[1990] Digest of papers.

It is the basis for a new product family specifically addressing high-data-rate applications. The first product is a 5.25-in full-height form-factor drive including the controller, with a capacity of 2 GB, which can be read or written in 11 min at a sustained data rate of 3 MB/s. It incorporates several significant technological advances including a read-while-write thin-film magnetoresistive read inductive write head, a new .25-in tape cartridge, and a heavily equalized data channel.
