Installation
Configuring/Connecting A/V HD Subsystem (RAID, optional)
The harddisk subsystem (A/V storage) is connected to the SCSI controller in the host PC via a
SCSI connecting cable.
Liquid Edition requires at least one (two recommended) U2W SCSI stream controller and
the Windows striping set technology (RAID 0) for the A/V hard disk subsystem, or a dedicated
RAID controller.
We recommend that a computer dealer or anyone else familiar with RAID and video
technology select and install the disk subsystem. Configurations other than the one
described here are possible.
At least one hard disk drive is required (two of the same type, one for each stream, when
using a dual ultrawide controller). If you connect additional hard disk drives, make sure
that the same number of hard disk drives are connected to each stream (same model,
same revision number of the firmware). Always take into account power supply and cool-
ing.
Setting SCSI IDs
Ultrawide SCSI supports up to 16 devices (including the SCSI controller) and each device must
have a different ID number (0 to 15). The SCSI controller normally uses ID number 7, so you
should avoid this number when setting the ID numbers for the hard disk drives.
Termination
SCSI controllers must be actively terminated. You must, therefore, terminate not only the hard
disk drives, but also the SCSI controllers located at both ends of the stream. If the hard disk drive
located at the end of the stream is not terminated internally, then an external terminator is
required.
