Imes in the Architecture of a Document Archiver using Optical DisL Technology S. Christodoulakis * Computer SystemsResearch Institute University of Toronto *Part of this work was done whtlt the author was visiting the Computer Research Institute of Crete ABSTRACT We present issues related to the architccturc of a document archivcr using optical disk technology. In parttcular we examine the problems of data placement in the optical disk, storage hierarchies, data duplication and version control. Simulation results and analytical results are presented. These results are used to analyxe the effect of various design decisions on the pcrformancc of such a system. 1. Introduction In today s offrccs there is a need for systemswhtch efficiently store and retrieve multimedia documents which contain information in the form of attributes, text, graphics, bitmaps and voice. Such systems will have to archive a large number of documents for a long period of time (m&me&a docvnoru mchivers). The users of these systemswill be able to accessmultimedia documents by specifying some informatum on the document s content. For such systemsto be succcsful accesstimes for multimedia documents should be small. In this paper we describe some architectural issuesrelated to the &sign of a document archiver and
