Configuring your Storage Creating a RAID Array 4 JBOD: JBOD lets you combine multiple disks of mixed capacities into a single logical storage device. The capacity of the JBOD array is the sum of the total capacities of the individual component disks (that is, it does not have the limitation of RAID0 where you lose some capacity when using mixed sized disks). JBOD offers no performance increase compared to the component disks. It has lower reliability than the component disks, as the failure of a single disk results, in general, in the failure of the whole array. Depending on how you create volumes on the JBOD array, you may be able to recover data when one or more disks in the JBOD fail. This, however, is not guaranteed. • Minimum Number of Disks: 1 • Total capacity: sum of capacities of component disks. • Advantages: Maximal storage capacity, especially when using mixed size disks. • Disadvantages: Decreased reliability. Creating a RAID Array To create an array: STEP 1 From the Manager Menu, click Storage RAID.
