PCUNIX/OL - Product Description
PCUNIX/OL is an Optic Library autochanger(jukebox) storage subsystem.
The unit has two magneto-optic(MO) read/write drives managed by a
picker unit. The device contains 32 media for a storage capacity of
over 20GB. An external mail port allows media to be inserted into or
ejected from the unit.
PCUNIX/OL may be used in many ways. An obvious use is in the role of a
network file server. Other creative uses are also possible. For
example, as a data duplication device the unit could be filled with
blank media and data could be duplicated onto the media for
distribution. Autochanger units of this data volume are relatively new
and the scope of their application will be expanded by creative system
integrators. The access to this device type by PC-based UNIX systems
will provide low-cost options for image management or large database
applications.
PCUNIX/OL may also be used in conjunction with PCUNIX/MO. PCUNIX/MO is
the desktop drive unit. PCUNIX/MO may be used at remote workstations
with PCUNIX/OL serving as the hub librarian. A great deal of floor
space may be recovered by converting mag tape libraries to optic
media-based libraries.
PCUNIX/OL is supported with both raw and block driver options. Each
autochanger unit uses three SCSI addresses. One address for each drive
and one address for the picker unit. The picker unit is supported only
as a raw device. The drive units may be accessed either as raw devices
or block devices mounted in the filesystem. The raw driver support
provides media-based directories, random access to media data, user
programmatic access, and tar compatibility. The block driver supports
making and mounting a filesystem on the media.
PCUNIX/OL is implemented on Santa Cruz Operation(SCO)'S UNIX 386/V
Operating System. The device drivers are user-installable with SCO's
custom program. The use of an intelligent controller with a 64K
on-board cache maintains a high sustained data transfer rate.
The basic product may be configured as a single 20GB unit or may be
packaged in a cabinet that will contain three units for a total of
60GB. The controller is Adaptec's AT/SCSI Host Adapter. It requires
one full-length slot. Each controller supports up to 2 units and each
host system will support up to 2 controllers. The subsystems may be
connected to the host via a SCSI peripheral cable of up to six feet in
length.
Hewlett-Packard's name has long been synonymous with quality products.
Software Horizons has selected these quality peripherals upon which to
build quality software products. This combination will provide solid,
dependable storage subsystems.
