Overview of Archive and Retrieve Operations

IRIS can archive, retrieve, and play radar data. If a RAW product (polar coordinate data) is retrieved from archive, IRIS can generate products from the retrieved data as if the data were collected in real time. Picture products can be retrieved from archive and then displayed. Supported devices include:

• Tape such as DAT

  Recording to tape is convenient, but retrieval can be slow if the file that you want is at the end.

• Optical disk drives

  Optical disks, such as re-writable magneto optical drives, are more expensive than tape, but last longer and are much more convenient to use because of their random access capability.

• Large Disk Archives (LDA)

  LDAs allow you to take advantage of low-cost mass storage systems.

• DVD+RW systems (for example, SONY DRU–500AX (internal), SONY DRX–500ULX (external on Firewire or USB 2.0).

  DVDs offer low cost for both the drive and the media while providing approximately 5 GB of storage. Supported on Linux systems.
