Chapter 2 Avid DS Hardware Overview

Disk Subsystem

In a standard configuration, one Integrated Drive Electronics (IDE) disk drive

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

MediaDock LVD or 12 SCSI disk drives in a MediaDock Ultra320. The

system disk drive is formatted with two 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 following table summarizes disk drive information for a standard

configuration.
