Configuring your Storage Managing RAID Arrays 4 • %Used: The percentage of space used on the USB flash device. • Action: The Unmount button unmounts the USB flash device so that it can be safely removed from the AUX-1 port. Managing RAID Arrays RAID is an acronym for Redundant Array of Inexpensive Disks. In storage environments, a RAID array uses multiple physical disk drives to create a single logical unit from which data can be shared or replicated between the drives. A RAID array also simplifies the data management as the data appears in one logical unit. Choosing to store your data using a RAID array gives you the benefit of speed and performance; storage capacity; decreased downtime costs and increased availability; fault tolerance; and higher data security. About the RAID Arrays Page Use the RAID Arrays page to manage the local RAID and JBOD arrays. To display the RAID Arrays page, from the Manager Menu, click Storage RAID.
