Volume Management for X-RAID

The X-RAID technology offers a simplified approach to volume management. X-RAID works on the premise that what most people want to do with their data volume over time is either adding redundancy or expanding it without the headaches usually associated with doing that. By using simple rules, X-RAID is able to hide all the complexities yet provide volume management features previously available only in enterprise-level storage solutions.

•X-RAID Redundancy Overhead. To maintain redundancy from disk failure, X-RAID requires a one-disk overhead. In a two-disk X-RAID volume, the usable capacity is one disk. In a three-disk X-RAID volume, the usable capacity is two disks. In a four-disk X-RAID volume, the usable capacity is three disks.

•X-RAID has One Data Volume. X-RAID devices have only one data volume. This volume encompasses one to four disks, utilizing the capacity of the smallest disk from each disk. For instance, if you had one 80 GB disk and two 250 GB disks, only 80 GB from each disk is used in the volume. (The leftover space on the 250 GB disks is reclaimed only when the 80 GB disk is replaced with a 250 GB or greater capacity disk. See “Replacing All Your Disks for More Capacity” on page 1-27.”)

Adding a Second Disk for Redundancy

A one-disk X-RAID device has no redundancy and provides no protection from a disk failure. However, if and when you feel the need for redundancy, simply power down the device, add a new disk with at least the capacity of the first disk, and power on. Depending on the size of the disk,
