Configuring your Storage Managing RAID Arrays 4 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 The RAID Arrays page is where you manage the local RAID and JBOD arrays. To display the RAID Arrays page, from the Manager Menu, click Storage RAID. Choosing a RAID Array Level RAID (Redundant Array of Inexpensive Disks) is a technology that enables multiple low-cost hard drives to be used together in a way that increases performance and/or reliability compared to that of a single drive. The component devices in a RAID array appear as a single logical storage device. There are various types of Cisco Small Business NSS2000 Series Administration Guide 42
