Defining Typical Application Usage
Allows the user to choose the type of PC usage that will be performed in order to
optimize how FastTrak100 handles data blocks to enhance performance. Your
choice will determine the block size used. You may choose from: A/V Editing (for
audio/video applications, or any similar application that requires large file transfers),
Server (for numerous small file transfers), or Desktop (a combination of large and
small file sizes).
Using a “Hot” Spare Drive
If a third drive is attached as a “Slave” and is not assigned to a mirrored two-drive
disk array (one optimized for “Security”), it will be recognized as a Spare Drive.
Such a drive is immediately used as a “standby” replacement. It is automatically
added to an array once a disk member of the array has been detected as “failed.”
To restore fault tolerance as quickly as possible, FastTrak100 begins to perform an
automatic data rebuild on the “spare” drive in the background without the need to
restart the system. At a later time, the failed drive can be physically removed from
the FastTrak100 card and an extra drive added in its place to function as the
“spare” drive.
Creating Multiple Disk Arrays
1. If you plan to create multiple arrays, attach only the drives necessary to create
the first disk array and complete the <1> Auto Setup.
2. Install the additional drives needed for the second array and again use the <1>
Auto Setup.
NOTE: If you wish to customize the settings of individual disk arrays (such as
block size), you must manually create disk arrays with the Define Array <3> option
from the Main Menu.
