Example text

It is necessary to connect to only one of the controllers in order to configure and set up your RAID. When you first take your Xserve RAID out of the box and plug it in, you will notice that the front drive lights are flashing, which means that the drives are creating the data set, and this might take some time. With a fully populated 7 TB RAID, the dataset creation will take approximately 40 hours. Each time you create a RAID set, expect the drives to take some time to do their stuff. The good news: A background formatting option allows you to use the RAID set almost immediately after the initialization has started.

In the event of drive failure, parity information can be used with data on the surviving drives to reconstruct the contents of a failed drive. Parity data can be stored on a dedicated drive, as in RAID 3, or distributed across an array of drives, as in RAID 5. Parity provides much greater storage efficiency than mirroringup to 85 percent for a set of seven drives.
