Specifications

Use one SCSI Channel for Pro Tools audio storage and the second SCSI
channel for video storage. If Compression levels of 2:1 or 1:1
(uncompressed) is desired then a 2nd Compatible Dual-Channel LVD SCSI
HBA card is required and video storage should be connected to this
controller.
Note: AVoption|XL supports "plug and play" compatibility with many Avid
systems. When "inheriting" a drive containing audio and video data from
an Avid system, we recommend you connect this drive to the SCSI
channel dedicated to video storage. There is no need to copy the audio
data from such a drive to your dedicated audio drives, however we
recommend that you not record any additional audio tracks onto this
drive.
Virtually all the testing for AVoption|XL was done with a baseline of 32
tracks of 24- bit/48k audio and one stream of uncompressed video data
(record and/or playback). These test configurations generally included one
drive for every 16 tracks of audio. One way to achieve higher track counts
is to dedicate more drives to the audio tracks.
On a supported configuration, you should be able to easily achieve this
performance baseline, even with a high degree of edit density on each
track. The higher the edit density, the more heavily taxed will be the
storage subsystem.
You may find much better results than this baseline, since Digidesign's
performance tests re designed to stress the storage subsystem more
heavily than the average "real world" usage. In several cases, our test
group was able to continuous record or playback of 48 audio tracks and
uncompressed picture simultaneously.
There are other possible steps that can be taken to maximize the
performance of a Pro Tools system with AVoption|XL. Consult the
