ATTO Technology Inc. FastStream SC Installation and Operation Manual

• 512 bytes is the default size for most

operating systems.

• For Windows XP (32-bit support) select 4 KB

sectors to enable large volume support
(greater than 2 TB).

15 Select a

SpeedRead option. SpeedRead looks

ahead during reads and stores the data in
cache memory.The optimum setting depends
on your actual I/O and storage. You may adjust
this setting later.

• Enabling SpeedRead may boost

performance when you are running video
playback and other applications which
access data sequentially.

• Disabling SpeedRead is a better choice for

audio applications.

• SpeedRead Auto is usually the best choice

for database applications.

16 Select a

Pre-Fetch option--the number of extra

stripes that are read when the

SpeedRead

setting is set to enabled or auto.

17 Select an

Auto-Rebuild option if it is available

for your RAID configuration (refer to

Auto-

Rebuild

on page 13).

18 Select a

Rebuild Priority. Rebuild Priority

allows you to determine whether rebuild or I/O
transactions take precedence during rebuild
operations. If you choose low priority, for
example, rebuilds take longer but the rebuild
has minimal impact on performance.

19 Click on

Next.

20 A chart showing the setup you have selected

appears. If everything is the way you want it,
click on

Commit to save your configuration.

21 A warning box tells you that all data on the

attached disks is to be destroyed and the
rebuild process may take up to two hours to
complete.
In the warning box, verify that you want to
complete the configuration by clicking on

Yes.

Clicking on

No ends the procedure without

making a change.

22 Click on

Commit.

Monitor page appears.
