Data General Winchester Disk Subsystem Replacement

The AEM-9C is plug-compatible with the original aging Data General Winchester disk systems, 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-9C.

The AEM-9C provides a complete bridge between the Data General Winchester disk subsystem controller and the AEM's internal data storage drives. Data General Winchester disk drives were widely used on computer systems since the late '70s and are still in use today on systems with specialized functions and custom software, making it impractical to re-host the complete computer system. Originally built as free standing floor models with removable disk packs, these drives were also produced in several styles of rack mount with removable packs, fixed - sealed media, or a combination of both.

While refurbished Data General Winchester Disk replacements have limited availability, refurbished Data General Winchester disk drives commonly fail within a few months resulting in system down time9C, with MTBF of 200,000+ hours and significantly more when using the solid state AFD.

Additional AEM-9C options include disk to disk backup, disk to tape backup, AFD network (backup & restore) and mirroring. No refurbished SMD replacement can match the reliability, features and customer support provided by choosing the AEM-9C to replace your aging and refurbished Data General Winchester Disk disk drives.

Features and Benefits

  • Replaces aging and refurbished Data General Winchester disk drives with new data storage technology.
  • 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.
  • 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.
  • AEM data storage can be to removable media, regardless of the original media. Ideal for secure applications.
  • Reduced power consumption compared to original Data General Winchester disk drives
  • The AEM is configured using internal software. The same model will emulate a wide range of disk drives.
    • System disk capacity may be increased if required.
    • Using the same AEM model for several drives limits the spares requirement.

Improved Performance and Features:

Fully Cached, SCSI Interface, Multiple Volumes, Offline Backup and Restore, Self Test, Reduced Power Requirement, Reduce Weight, Plug Compatible with original drive, and 3U 19” Rack Mounting  Low Maintenance - Reliable Operation

The AEM-9C uses ARRAID’s proprietary FPGA based solid state SCSI flash drives (AFD) for low maintenance operation. Drives are rated in excess of 300,000 hours MTBF and up to five years of continuous operation. This will be significantly more when using the solid state (AFD)

Drives appear defect-free to the host computer. Backup drive option is available in either fixed or removable ARRAID Flash Drice (AFD) configured as a Hard Drive, Magneto Optical, DAT Tape, or removable PCMCIA Flash
