Next-Generation File System
A modern le system designed to address obstacles
often encountered in enterprise storage systems,
safeguarding data integrity through metadata
mirroring, self-healing and snapshot replication.
Btrfs: Next Generation Storage Efficiency
RS820+/RS820RP+ introduces Btrfs file system, bringing the most
advanced storage technologies to meet the management needs of
modern business:
• Advanced snapshot technology provides schedulable and
near-instantaneous data protection of share folders and iSCSI LUNs.
• File and folder level data restoration brings great convenience and
saves time for users who wish to restore only a specific file or folder.
• Flexible Shared Folder and User Quota System provide
comprehensive quota control on all user accounts and shared
folders.
• File self-healing allows Btrfs file system to auto-detect corrupted
files with mirrored metadata, and to recover broken data using the
supported RAID type of volumes, including RAID1, 5, 6, and 10.
Reliability, Availability, and Disaster Recovery
System reliability is critical for business everywhere. RS820+/RS820RP+
responds to these concerns with wide-ranging availability and
redundancy features:

clustered servers in unexpected disasters and ensures that your
services remain online.
• Snapshot Replication provides schedulable, near-instantaneous
data protection, ensuring that your business documents in shared
folders, virtual machines in iSCSI LUNs, or dockerized application
data remain safe and available in a disaster.
• Redundant power supplies (RS820RP+ only), system fans and
network ports with failover support ensure continual service
uptime.
• High reliability system design, including fan-less CPU heat sink and
passive cooling technology, prevents single points of failure.
• Optional 5-year warranty1 is available in select regions.
