• Server design
  
  
  • Reader, cache, and infeed machines are mid-level server with 9GB boot and two fast 18GB data drives, striped for /news
    
    
  • Spool server machines are high-end servers with external disk shelves (2 shelves x 9 drives x 18GB for text, 4 x 9 x 50GB for binaries, 1 SCSI bus per shelf)
    
    
    • One minor concession to on-machine redundancy: since the text spool can retain ~180 days of text, losing the history would be a pain, so the /news partition is mirrored
      
      
    • Use Diablo spooldir patch to create multiple spool drives, so that a loss of one drive does not wreck the entire spool, but rather only a portion of it
