An Open-Architecture Approach to Scaleable Data Capture

摘要

The ultra high capacity disk-based data recorders now entering service offer not just a convenient and inexpensive alternative to conventional tape systems for applications like Telemetry and Flight Test but also a unique opportunity to rethink the classical models for data capture, analysis and storage. based on 'open architecture' interface standards-typically SCSI-this new generation of products represents an entirely new approach to the way data is handled. But the techniques they employ are equally applicable to any SCSI sotrage device. This Paper discusses a range of practical scenarios illustrating how it is now possible to. 'mix-and-match' recording technologies at will-disk-array, DLT, DTF, ExaByte, JAZ, ZIP, DVD, etc.-to produce an almost infinite combination of readily scaleable plug-and-play data capture, analysis and archiving solution.s The cost and reliability benefits arising from the use of standard mass-produced storage sub-systems are also considered.
