Components

Hard Drives

Storage Transfer Drives (STDs)

Purpose: storage media for copies of acquired media or SIPs arranged by archivists

Requirements:

• Minimize transfer time
  • Limiting factor for transfer rate is likely bus transfer rate, not read/write speed of disk.
• At least 1TB in size
• Flexibility to interface with different types of Producer systems
• reliable, not prone to overheating

Hardware:

• Internal drive, plus
  • Portable drive enclosure(s)
  • Interface Options - USB 2.0/Firewire
    • eSATA not desireable for transfer from producer systems - requires eSATA card on producer computer; still desirable for copying onsite

HDD formatting:

• Windows - use NTFS
• Mac - HFS+ (Mac non-journalled)
• Linux - ext2

Need: 20-30 hdds 4-6 enclosures

STD copies

Purpose: Storage media for back-up copy of STD/SIP until ingest is complete and AIP storage is confirmed Requirements:

• Different brands/manufacturers to minimize risk of systematic mfg failure

Same options as for STDs

DA Stations

Duplication Station

Purpose: Make back-up copies of STD

Requirements Processing power

Hardware PC - no Windows O/S (run Ubuntu natively) 2 or 4 bay enclosure w. eSATA connection

Processing Station

Purpose: Transforms SIP(s) taken from STD to AIP(s) and writes to Archival Transfer Disk (ATD)

Requirements:

• Lots of processing power
• I/O Interface; either:
  • USB/Firewire/eSATA ports
  • link to external hdd enclosure - multi bay (2-4 drives)

Archival Transfer Station

Purpose: Reads AIP(s) from ATD and uploads to networked archival storage

Requirements

Hardware

Mac Station

Purpose Appraising mac specific formats - mostly audio, video and image formats and related software
