Introducing The Mirage Data Recorder (MDR)

The Mirage_DR  is designed to meet the requirements of Mission Critical Data Recording Applications such as Seismic Data Acquisition.  Tape drives and tape cartridge(s) are replaced by two disk drives enclosed in shock resistant removable cartridges, delivering increased performance and superior reliability. The Mirage_DR provides fault tolerant recording to two removable disk drives in a RAID-1 configuration. Recording continues in the event of a single disk drive failure.  The Mirage_DR copies data from the virtual volumes on the disk cartridge to conventional tape cartridges for processing or archive as required.

Transparent Operation – The Mirage_DR appears as an IBM 3590/3592, or LTO tape drive to the system providing plug and play compatibility.  The ability to process directly from the disk cartridges greatly increases throughput and reliability of existing acquisition operations.  Mirage_DR implements a Virtual Tape Autoloader with Multiple Virtual Tape Volumes. Mirage_DR automatically loads the next virtual tape volume upon executing the unload command from the server.  Each virtual volume can be loaded manually using the operator front panel.

RDM (Removable Disk Modules) Features – RDM’s are managed as a pair with automatically generated unique matching identification numbers. Each disk drive is mounted in a shock tolerant drive carrier. The data on the disk is recorded in actual tape format. All tape formats are supported including SEG-D and SEG-Y. RDM’s can be written to, retrieved from, write protected, stored, archived to conventional tape, erased and returned to the field like conventional tape cartridges.  RDMs are available with a variety of disk technologies and solid state devices.

Tape Drive Archive –The Mirage_DR features a built in stand alone, operator initiated, high-speed archive to conventional tape drives.  This feature copies data from the virtual volumes on the RDM to conventional tape cartridges. The tape cartridges created are identical to tape cartridges generated directly by the recording system.   Mirage_DR supports up to two tape drives, creating up to two tape cartridges at once.  Operations include Archive, Archive and Verify and Verify Only.

Higher Data Protection – Mirrored disk drives provide an instant backup copy. The Mirage_DR also offers additional data protection by automatically write-protecting virtual tape volumes until they are successfully archived.

Real Time Monitoring – Read After Write (RAW)    Mirage_DR offers Real Time display of seismic data files via a secondary independent host port.  Seismic data is retrieved and displayed via the monitor port while the MDR primary host port is used to simultaneously record seismic acquisition data providing 100% assurance in data acquisition.

 System Compatibility – MDR is 100% compatible with Data Acquisition systems from Sercel, ION, ARAM, and Fairfield Industries.

Mirage Data Recorder Specifications
