[. . . ] Click Yes to confirm the write policy mode you have chosen. Select Size: Specify the size of the virtual drive in terabytes, gigabytes, megabytes, or kilobytes. Normally, this would be the full size for RAID 50 shown in the Configuration panel on the right. You may specify a smaller size if you want to create other virtual drives on the same drive group. Yes: Select Yes if you do not want to allow background initializations for configurations on this controller. 17. Click Next when you are finished defining virtual drives. The configuration preview screen appears. Check the information in the configuration preview. If the virtual drive configuration is acceptable, click Accept to save the configuration. Otherwise, click Cancel to end the operation and return to the WebBIOS main menu, or click Back to return to the previous screens and change the configuration.

With two independent parity blocks, RAID 6 can survive the loss of two drives in a virtual drive without losing data. Use RAID 6 for data that requires a very high level of protection from loss. RAID 6 is best suited for networks that perform a lot of small input/output (I/O) transactions simultaneously. It provides data redundancy, high read rates, and good performance in most environments. In the case of a failure of one drive or two drives in a virtual drive, the RAID controller uses the parity blocks to recreate all of the missing information. If two drives in a RAID 6 virtual drive fail, two drive rebuilds are required, one for each drive. These rebuilds do not occur at the same time. The controller rebuilds one failed drive, and then the other failed drive. When you select Manual Configuration and click Next, the Drive Group Definition screen appears. You use this screen to select drives to create drive groups. Hold <Ctrl> while you select at least three ready drives in the Drives panel on the left. Click Add To Arrary to move the drives to a proposed drive group configuration in the Drive Groups panel on the right. Select a preferred Power save mode. [. . . ] Yes No 4.
