WP5: Provide data storage to ASTRO-WISE

Objectives:
  • provide the necessary direct access data storage to the prime data centers; typically 1 Tbyte/ site direct access, upgradable to 10 Tbyte/site within two years
Work description:
  • hardware procurement and installation
  • hardware maintenance

Planned total man month over 4 years (from contract)

Phase I: be ready to receive first data without later redefinition or re-shuffling - 2002
  1. T0 kick-off- prepare design review WP5
  2. T0 + 1Q procurement WP 5 -(small prototype one-few Tbyte storage)
  3. T0 + 2Q WP5 start sub-component installation
  4. T0 + 3Q WP1 fully operational with first version of WP5
Phase II: evaluate and prepare for mass production -2003 -2004
  1. T0 + 9Q Upgrade of mass storage WP5- ready for bulk operations deliverable: qualified export version to satellite sites
  2. T0 + 10Q System full mass production proof (i.e. 100 Tbyte data volume)
Phase III: qualify, operate and populate the mass production system -2005
  1. T0 + 11Q Review and set goals of final delivery system
  2. T0 + 15Q Deliverable:- Mass storage system at partners centers supporting the ASTRO-WISE infra-structure
