Infortrend RAID Controller Manual

Optimization for Random or Sequential I/O
Choose “Optimization for Random I/O” or “Optimization for
Sequential I/O,” then press [ENTER]. The “Random” or
“Sequential” dialog box will appear, depending on the option you
have selected. Choose Yes in the dialog box that follows to confirm
the setting.
Write-Back/Write-Through Cache Enable/Disable
Choose “Caching Parameters”, then press [ENTER]. Select “Write-
Back Cache,” then press [ENTER]. “Enabled” or “Disabled” will
display the current setting with the Write-Back caching. Choose Yes
in the dialog box that follows to confirm the setting.
The write-back cache function significantly enhances controller
performance. Write-through strategy is considered more secure if
power failure should occur. However, if the battery module is
installed, power will be supplied to the data cached in memory and
the cached writes can be completed when power is restored.
