Mass Memory Emulator

MTDE magnetic storage emulator is an electronic device addressed to companies using traditional SCSI bus storage media, such as tape drives (called rewinders), streamers, magneto-optical disks. The solution meets the needs of telecommunications operators having digital telephone exchanges in which the above-mentioned data carriers are used. MTDE emulator replaces magnetic drives used in telecommunication exchanges, both for billing and system data transmission.

Thanks to the use of modern electronic circuits and specialized software, the MTDE device is suitable for emulation of any drives using recording on magnetic media and magneto-optical disks.

Magnetic mass memory emulator

Principle of operation
  • Increase system reliability by eliminating failed mechanical magnetic and magneto-optical drives.

  • Reduction of costs related to archiving central data

  • Automation of the process of collecting central data
  • The ability to remotely manage the device
  • Reduce maintenance costs

The MTDE emulator, from the point of view of the system in which it is installed, is visible as a standard physical drive, such as a magneto-optical drive, streamer, tape drive. The device behaves identically to the original drive. The emulator is equipped with three connectors: SCSI, Ethernet, and power supply. The SCSI and power connectors are used for direct connection in place of the emulated physical drive.
The Ethernet connector is used to connect to the control computer, which stores data read from the system or data to be written. Specialized software is installed on the control computer, allowing remote operation of the emulator in the same way as if it were a standard SCSI device (e.g., insert a disk of the appropriate size, perform disk diagnostics, write data to the disk, read data from the disk, remove the disk).
All operations are performed on the so-called virtual media. The virtual medium is a part of the hard disk capacity of the control computer, which is used to store information transferred to/from the emulator. The data stored on the virtual medium can be made available to other systems via IP network or in any other way according to customer requirements.

Data safety

Replacement of magnetic carriers

MTDE emulators eliminate the need for manual handling of traditional data storage media (inserting media, removing media), thus allowing for easy implementation of an effective data archiving system.

Using an MTDE emulator can extend the life of systems using often hard-to-reach mechanical magnetic and magneto-optical SCSI drives.

Emulators significantly reduce maintenance costs (OPEX) eliminating the need to purchase very expensive specialized SCSI drives and media.

The use of MTDE emulators significantly increases the security of data stored in systems by providing an additional buffer of data in the control computer’s disk space.


  • reduce maintenance costs (OPEX) by eliminating the need to purchase hard-to-find, obsolete SCSI mechanical media,
  • extend the life of current systems using SCSI mechanical media,
  • increase system reliability by eliminating failed mechanical magnetic and magneto-optical drives,
  • eliminate the need for manual operation of drives,
  • automation of data transfer processes to/from devices allowing, among other things, for scheduling of data retrieval,
  • automate central data retrieval and backup,
  • fully remote device management and configuration from a dedicated software tool, 
  • ability to use the device as an additional buffer to protect against data loss,
  • a housing that matches the size of the drive being emulated (magneto-optical disk, streamer) so that the emulator can be mounted directly in a place of the drive being replaced.
