The 270011-1490 is the Exabyte EZ-17 7 tape autoloader with a Mammoth2 LVD SCSI drive fitted.
The Exabyte Mammoth-2 was the fifth drive in Exabyte’s highly succesful half height 8mm format that has gained industry recognition for its quality and reliability. First released in 1987, The standard half height 5.25-inch half height form-factor allows easy installation and integration into most PC servers and workstations.
The tape backup system packed 60GB of native data onto a 225M AME tape similar to a Hi8 / Sony D8 camcorder video cassette. Applying helical scan recording technology, which had been used in video products for 30 years, Exabyte produced a compact, relatively inexpensive eight-millimeter tape cartridge drive which could hold unprecedented amounts of data.
Unlike other backup formats at the time, the tapes could also be conveniently removed and stored in a vault. The EXB-Mammoth-2 was a progression of the exabyte 8mm family and used a new 170M tape.
In contrast to conventional tape drive technology, Exabyte’s helical scan device employed relatively slow-moving tape using heads mounted on a rapidly rotating drum. This method offered several advantages contributing to high recording density.
The need for "tight tolerance" was considerably reduced as the tape drive used only one or two short tracks at a time, rather than multiple, lengthier tracks found in conventional parallel track recording. This method meant that recording tracks could be run closer together. In addition, the helical scan technology permitted the tape to run at a slower rate producing far less stress on the tape. In turn, less stress meant that thinner metal particle tape could be used to record at high densities.
Data tapes used by Exabyte in these 8mm format drives do indeed have a width of 8mm but varied in length.
The Exabyte Mammoth-2 half height tape drive is an mid generation of the Exabyte 8mm family. It was manufactured by Exabyte for vendors including IBM, Sun and many others for use as standalone internal and external drives targetting both the enterprise as well as later the small business market. This drive format was manufactured in vast quantities and was at one point the most widely used format.
The Exabyte Mammoth-2 offers 60GB native capacity on a single 225M AME tape at transfer speeds of up to 12MBps or 43.2GB per hour Native.
The Exabyte EXB-Mammoth-2 does support data compression and uses the 225M AME tape media.
The Exabyte Mammoth-2 offers 60GB native capacity or 150GB compressed capacity on a single 225M AME tape at transfer speeds of up to 30MBps or 108GB per hour. Native, the drive provides 60GB of storage capacity with a transfer speed of 12MBps.
The Exabyte Mammoth-2 had an useful LCD screen to show the drive status and was available in a 68pin LVD SCSI and HVD SCSI interface versions in both internal and external configurations.
The Exabyte Mammoth-2 was also available in an External Fibre channel configuration.
