Page 50: Managing Raid Arrays
Configuring your Storage Managing RAID Arrays 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.
Page 51 Configuring your Storage Choosing a RAID Array Level RAID, referred to as RAID levels. Some RAID levels increase the performance of the array, some increase the reliability, and others do a mixture of both. The NSS supports the following RAID levels: 0 and 1. The NSS also supports JBOD (Just a Bunch of Disks), which is technically not a RAID level.
Page 52 Configuring your Storage Choosing a RAID Array Level 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).
Page 53: Creating A Raid Array
Configuring your Storage Creating a RAID Array Creating a RAID Array After you install the physical disks, you can create the RAID arrays. Before you create a RAID array, either for the first time, or when you are rebuilding it as a result of failed disks in the array, it is a good idea to set the Rebuild Priority (see ”Storage Options”...
