Fujitsu M2485B Tape Drive

Small Size for Easy Installation
Fujitsu M2483B and M2485BThe M2483B rackmount drive has an embedded SCSI-2 interface controller, reducing the subsystem’s size to 127 mm high, 217 mm wide, and 380 mm deep (5 inches high, 8.5 inches wide, and 14.9 inches deep), significantly smaller than most of its counterparts. The 8-inch form factor of the M2483 allows easy, space-saving integration into industry-standard 19-inch racks.

The M2485B desktop drive is completely self-contained and has a small footprint of only 222 mm x 650 mm (8.7 inches x 25.6 inches) with external automatic cartridge loader, and is well suited for a convenient desktop configuration.

High Performance and Reliability
The M2483B and M2485B tape drives, with 2-megabyte buffers, can attain a continuous stream of data input/output that offers a sustained data transfer rate of 3.0 megabytes per second and a burst rate of 4.0 megabytes per second in the synchronous mode. These cartridge tape drives are supported by Fujitsu’s enhanced data recording capability (EDRC), the data recording method compatible with IBM’s improved data recording capability (IDRC). Fujitsu’s advanced LSI technology has resulted in a streamlined design and
simplified tape path, contributing to the high reliability of these drives. In fact, the mean time between failures (MTBF) rating of these drives is more than 30,000 hours, among the highest in its class.

Flexible Options
The M2483 and M2485 3480 tape drives support both five and ten-cartridge magazines.
