Managing BlackArmor Volumes, Shares and Storage • Volume C: Media Files You could then create one or more folders (shares) in each volume to suit your needs: • Volume A: Business Files • Share 1: Client Files • Share 2: Financial Files • Share 3: Human Resources Files • Volume B: Backup File Storage • Share 1: Daily Backups • Share 2: Month-end Backups • Volume C: Media Files • Share 1: Music Files • Share 2: Photo Files • Share 3: Video Files Working with Volumes By default, the available storage space in your BlackArmor server is configured into one volume that's protected by RAID 5. Understanding RAID RAID stands for Redundant Array of Independent Disks and is a technology that builds redundancy into your storage system to help keep your data safe from disk drive failures and other catastrophes. RAID comes in many levels, which vary according to the amount of protection they provide (and how they provide it), and the number of disk drives they support. By default, your BlackArmor server is preconfigured with RAID 5, which not only stores your data safely but also builds in redundant information called parity, which is data that's used to reconstruct your files if one of the disk drives in the server fails. You can choose to use a different level of RAID protection for your volumes-your BlackArmor server supports RAID levels 0, 1, 5, 10, and JBOD (which stands for Just a Bunch of Disks). However, RAID 5 is highly recommended as it provides the best level of protection available on your BlackArmor server. BlackArmor® NAS 440/420 User Guide (Version 3) 31
