| Abstract: |
The Hubble Data Archive now contains in excess of 2.5TB of HST data in a system of four optical disk jukeboxes. In addition to providing a WWW-based user interface %(see Kimball, Sanidas, & Mayhew 1997) and and removing a custom I/O processor (see Travisano & Richon 1997), STScI has undertaken a high-level effort to improve the operating efficiency, reduce costs, and improve service to archive users. The HARP group is studying data compression, data segregation, large on-line disk caching, on-the-fly calibration, and migration to new storage media. In this paper, we describe the results of our cost-benefit analysis of these and other options for re-engineering the HDA\@. |
