The TES-4 emulates tape drives that adhere to the industry standard Unformatted Pertec protocol.

The TES-4A emulates the Thorn EMI version of that protocol.

Tape speed is typically 45ips, Start/Stop only. Recording densities from 800bpi NRZ mode to 1600fpi PE. The TES-4/4A can replace an existing drive or may be added to the existing tape drive chain.

The TES-4/4A is plug-compatible with the original tape drives, while using ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) to store data. Internal TES rotating drives (disk, tape & magneto-optic) can still be supported upon request.

No host system software or controller changes are required to replace a refurbished  Pertec/EMI Industry Std Tape Drive with the TES-4/4A

Additional TES-4/4A 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 TES-4/4A to replace your aging and refurbished tape drives.

Additional TES-4/4A options include AFD network (backup & restore) offering Ethernet based tape data access, and replacement of tape reels with solid state ARRAID Flash Drive (AFD) configured as a magneto optical or legacy PCMCIA flash card media. No refurbished Pertec interface tape drive can match the reliability, features and customer support provided by choosing the TES-4A to replace your aging Pertec tape drive.

The TES-4/4A is provided as new equipment, allowing customers to utilize SCSI drives or ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) installed in the TES-4/4A, with MTBF of 200,000+ hours and significantly more when using the solid state AFD.

Features and Benefits

  • 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 TES 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 LCD Operator Panel provides full control over drive functions.
  • High reliability with near zero maintenance required.
    • Greater computer system availability with lower cost of ownership.
  • The recomended TES storage output is to the solid state ARRAID Flash Drive (AFD) which uses industrial grade CompactFlash (CF) cards.
    • With tape head alignment no longer an issue, media may be moved from drive to drive without concern for readability.
  • Stores the content of multiple 1/2-inch tape reels on a single piece of CF media.
    • This allows for unattended operation (no tape reel changes) in many applications.
    • The space required for media storage is greatly reduced.
