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 as well as high data transfer rate. The
12/24GB 4mm Tape Drive uses 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 2.0 GB and 4.0 GB 4 mm tape drives. The 12/24GB
4mm Tape Drive can be used as a boot device.
The tape drive is used primarily for:
v Saving and restoring system data files
v Archiving important records
v Distributing operating system software upgrades.
The drive conforms to the American National Standards Institute (ANSI) SCSI-2
standard.
The 12/24GB 4mm Tape Drive’s features include:
v Use of 12/24 GB 4 mm data cartridges.
v Data rate of 1.1 MB/second.
v Capacity of 12 GB.
v Compression capability, which effectively doubles the native capacity of 12 GB 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.
v A half-high 5.25-inch form-factor.
