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 

 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 

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 

23 The FastStream configures the storage: the 

process may take several hours. When the 
process is complete, the 

Monitor page appears.
