Chapter 3 • System Overview

Disk Subsystem

In a standard configuration, one Low-Voltage Differential Signaling (LVDS)

SCSI disk drive is installed in the base unit, and eight LVDS disk drives are

installed in the Avid MediaDock LVD. The system disk drive is formatted with

three partitions for storing operating system files, project files, and audio files.

The Avid MediaDock LVD drives are formatted as a striped volume for video

file storage.

Disk striping is a hardware capability that speeds up data I/O from disk

storage. The workstation divides the data into pieces, and spreads the pieces

across the disks in the striped volume. Because the workstation transfers data

to multiple drives in smaller chunks than would be transferred to a single

drive, the data transfer rate is accelerated. The Adaptec 39160 adapter handles

data I/O for the video storage drives.

The following table summarizes disk drive information for a standard

configuration:
