Typical Application Usage

The user can choose the type of PC usage to be performed in order to optimize the way the

system handles data blocks that will help enhance performance. Your choice will determine

the block size used. You may choose: 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).

NOTE: To customize the settings of individual disk arrays (such as block size), you must

manually create disk arrays in Define Array <3> of the Main Menu.

Viewing Drive Assignments

“View Drive Assignments <2>” in the Main Menu displays whether drives are assigned or

unassigned to disk arrays.

The menu also displays the data transfer mode that relates to speed used by each drive (U6

refers to 133MB/sec transfers, U5 refers to 100MB/sec transfers, U4 refers to 66MB/sec

transfers, etc.)

How the RAID Controller Orders Arrays

During startup, the disk arrays are recognized in this order: 1) The array that is set as

bootable in the FastBuild

Setup, and 2) The Array number (i.e. Array 0, Array 1). This will

involve determining the drive letters assigned to each disk array.

How the RAID Controller Saves Array Information

All disk array data is saved into the reserved sector of each array member. We recommend

that you record all disk array information for future reference.

Another feature of the disk array system is to recognize drive members even if drives are

moved between different connectors. Since each drive’s array data identifies itself to the

array, it is possible to move or swap drives without modifying the array setup. This is

valuable when adding drives, or during a rebuild.
