HP 79XX MAC Disk Drive Emulation

The Arraid AEM-6C system provides a new and warranted equipment replacement for HP 7905, 7906, 7920, and 7925 disk drives connected to an HP 13037 Multi-Access Controller (MAC).

The AEM-6C is is plug-compatible with the original aging SMD drive, while using ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) to store data.  Internal AEM rotating drives (disk, tape & magneto-optic) can still be supported upon request.

No host system software or controller changes are required to install the AEM-6C.

The AEM-6C provides a complete bridge between the host HP MAC controller and the AEM's SCSI drives. HP 7905, 7906, 7920, and 7925 drives are used on HP-1000 computer systems with specialized functions and custom software, making it impractical to re-host the complete computer system.

While refurbished HP 7905, 7906, 7920, and 7925 drives have limited availablity, refurbished drives commonly fail within a few months resulting in system down time. The AEM-6C is provided as new equipment,allowing customers to utilize SCSI drives or ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) installed in the AEM-6C  with MTBF of 200,000+ hours.

Additional AEM-6C options include disk to disk backup, disk to tape backup, AFD network (backup & restore) and mirroring. No refurbished HP MAC replacement can match the reliability, features and customer support provided by choosing the AEM-6C to replace your aging HP MAC disk drive.

Features and Benefits

  • Replaces aging and refurbished HP 7905, 7906, 7920, and 7925 drives with new SCSI drives.
  • ARRAID Flash Drive (AFD) option is a Solid State SCSI disk replacing traditional mechanical SCSI drives (DAT, QIC, Tape & Magneto Optical Disk)
  • Additional features such as network backup, mirroring, restore and removable media can be added.
  • The CompactFlash (CF) media in the ARRAID Flash Drive (AFD) is treated exactly the same as the floppy disk media. All drive data is stored on the CF media as if were the original diskette media.
  • AFD network feature option offers LAN network (ethernet-based) back-up and restore capability directly from the AFD using the on board RJ45 Network port. No additional software or register changes are required to the legacy host. Including ARRAIDs FLASH2GUI Software, an optional ethernet support feature for centralised backup and restore capability lessening the reliance to rotate media.  Network option only available on AEM with AFD network drive installed.
  • Easy to install. No hardware or software changes required, other than the drive itself.
  • Can replace or be added to existing drives.
  • Operating system, application and diagnostic software are supported as is.
  • An LED or Alpha-Numeric Operator Panel provides the same controls as the original drive.
    • Minimal Operator training required.
  • High reliability with near zero maintenance required.
    • Greater computer system availability with lower cost of ownership.
  • Reduced power consumption compared to the original drive.
  • HP data can be stored to 3.5" magneto optical cartridges.
    • With disk head alignment no longer an issue, media may be moved from drive to drive without concern for readability.
  • The AEM is configured using internal software. The same unit will emulate 7905, 7906, 7920, and 7925 disk drives.
    • System disk capacity may be increased if required.
    • Using the same AEM model for several drives limits the spares requirement.
