Customizing Your Seagate® NAS Understanding RAID The following table provides information for all Seagate NAS models. You may not have all disk configurations available for your new volume creation. Table 2: Disk Configurations Disk(s) 1 2 3+ Volume Type Spanned Spanned, striped or mirrored volume. Spanned, striped or mirrored volume (with RAID 5) • Volume Encryption: Optionally enable volume encryption. Note: Make sure there is a USB drive inserted in the Seagate NAS's USB port if you want to enable volume encryption. The security key is saved to the drive during the encryption process. • Raw Volume: Optionally create a block-level (raw) volume. Note: Virtualization (iSCSI) requires a raw volume. • Volume Size: Enter a volume size and optionally set the volume size to be the maximum. 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 Seagate NAS is preconfigured with a RAID protection level: • Seagate 1-Bay NAS: No RAID protection available. • Seagate 2-Bay NAS: RAID 1 • Seagate 4-Bay NAS: RAID 5 Seagate Business Storage NAS Administrator Guide 20
