SCSI Converters (Single-ended/HVD/LVD)
Over the many years in which SCSI has been in use as the primary protocol for connecting storage devices to computers, the electrical characteristics of the protocol has changed in step with the performance of each new generation of disk and tape drives. This has lead to 3 types of SCSI buses: Single Ended (SE), High Voltage Differential (HVD) and Low Voltage Differential (LVD).
Tape Connection
Tape Array 40
The latest development from Digital Interfaces Ltd to meet the tape performance needs of the modern computing environment.
The DIL Tape Array 40 is a high performance dual slave channel tape array which is attachable to most midrange computers - for example the IBM AS400- and Unix platforms in both the open and proprietary operating system environments.
Typical users include video, geophysical, aerospace and critical transaction intensive applications in such areas as CAD development, banking and finance.
By use of DIL emulation techniques, a full range of tape drives and libraries can be connected to computers such as the IBM AS400, Unisys and Tandem.
The DIL TA40 can be implemented with one or two drives within a library or as stand alone drives offering high speed emulation attachment with the options of data striping for increased transfer rates and capacity, mirroring for fault tolerance and off site copy creation, or cascading for increased capacity.
Use of multiple TA40 cards allows the use of multiple drives within libraries.
Tape Array 80
Ultra-2 Connectivity for SCSI Tape Drives
The Tape Array 80 is an intelligent SCSI controller providing two independent SCSI Tape interfaces which support dual drive functionality for a full range of tape subsystems, and allows connectivity to the ANSI standard FAST-40 (SPI-2) parallel interface standard.
Tape Emulator 40
This recent development from Digital Interfaces Ltd meets the tape connectivity needs of the modern computing environment.
The DIL Tape Emulator 40 is a high performance single channel tape emulator which is attachable to most midrange and Unix platforms in both the open and proprietary operating system environments. Examples of midrange platforms include the IBM AS400 range; Unisys A Series, and Tandem.
Implementing the full range of Quantum DLT, Exabyte 8mm and Sony 8mm devices, most ½? cartridge drives, and many of the NEW tape formats, the TE40 offers outstanding performance and flexibility above other main frame class type products. The TE40 also supports library and stacker functions, delivering plug and play capacity and functionality where Magstar 3590 and 3570 devices are supported on the host machine.
Legacy
8844 SCSI host to Pertec Peripheral
The 8844 SCSI host to Pertec Peripheral is a microprocessor controlled board developed to enable Pertec Interface Magnetic Tape Drives to be connected to SCSI host platforms.
The 8844 implements a custom designed chipset comprising of a dual channel Direct Memory Access (DMA) controller and a Pertec Interface controller which together allow a high data transfer rates across both host and slave interfaces simultaneously.
Primary applications are in the communication and telecoms industry where modern exchanges using SCSI interfaces still rely upon Pertec ½" magnetic tape units (MTU's) to record logging and billing information.
SPERAD
Unattended backup of data on pertec interface hosts is now possible with the high capacity SPERAD subsystem. By emulating ½" 9 track tape drives the compact unit enables modern high capacity SCSI devices to be attached to the pertec tape interface on a wide range of host platforms. Through the tape deck emulation the SPERAD subsystem is able to be connected as a direct replacement to the existing device making software modifications and additional internal controllers unnecessary.
