General information for the 12/24GB 4mm Tape Drive
The 12/24GB 4mm Tape Drive is an internal streaming tape drive that provides
medium to high capacity backup and archival capability and a high data transfer rate.
The 12/24GB 4mm Tape Drive utilizes NARROW bus (8-bit) architecture.
Communications on the SCSI bus can be either asynchronous or synchronous. The
12/24GB 4mm Tape Drive is compatible with existing 2.0GB and 4.0GB 4mm tape
drives. The 12/24GB 4mm Tape Drive can be used as a boot device.
The tape drive is used primarily for:
Ÿ
Saving and restoring system data files
Ÿ
Archiving important records
Ÿ
Distributing operating system software upgrades.
The drive conforms to the American National Standards Institute (ANSI) SCSI-2
standard. You can attach the drive to any system that uses a single-ended interface
that meets SCSI-2 Standard ANSI X3.131-1994.Rev 10h.
The 12/24GB 4mm Tape Drive's features include:
Ÿ
Use of 12/24GB 4mm data cartridges.
Ÿ
Data rate of 1.1MB/second.
Ÿ
Capacity of 12GB.
Ÿ
Compression capability, effectively doubles the native capacity of 12GB and the
effective data rate. The actual capacity per cartridge varies depending on the
application and the type of data cartridge being used. The default is
compressed. Use SMIT to change the default.
Note: The factory default setting is
Activated. Data compression is usually
controlled by the application software.
Ÿ
A half-high 5.25-inch form-factor.
Ÿ
Status lights that indicate:
– When it is time to clean the tape drive
– When the tape is in motion
– When the drive is ready to accept tape motion commands.
