Info

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. Terminal Operation 8-3
8-4 IMPORTANT! • The default optimization mode is for "Sequential." Optimization mode for sequential is automatically applied to any logical configuration of drives larger than 512GB. 8.3 Viewing the Connected Drives Prior to configuring disk drives into a logical drive, it is necessary to understand the status of physical drives in your enclosure. Use arrow keys to scroll down to “View and Edit SCSI Drives.” This will display information of all the physical drives installed. To learn more about the legends used in each column, please refer to the previous chapter. Drives will be listed in the table of “View and Edit SCSI Drives.” Use arrow keys to scroll the table. You may first examine whether there is any drive installed but not listed here. If there is a drive installed but not listed, the drive may be defective or not installed correctly, please contact your <strong>RAID</strong> supplier. <strong>Infortrend</strong>
