Its feature set covers file backup and synchronisation, snapshots, cloud-account backup, cloud storage gateways and capacity expansion for teams building a centralised storage platform.
Key features and benefits
10GbE SFP+ built in
Two 10GbE SFP+ ports support bandwidth-intensive file sharing and backup.
Multi-gigabit copper ports
Two 2.5GbE RJ45 ports add flexible network access alongside SFP+.
Snapshot protection
Snapshots record system status and data to support recovery from accidental deletion or malware.
HBS backup workflows
Hybrid Backup Sync supports backup and synchronisation across NAS, servers and cloud storage.
Hybrid-cloud gateways
Cloud storage gateway support can combine cloud services with local NAS cache space.
PCIe and storage expansion
A PCIe slot and stated TR RAID or TL JBOD support provide expansion paths.
Who is this model best for?
A strong choice for
- 10GbE SFP+ file sharing
- Business backup and synchronisation
- Cloud-account backup with Boxafe
- Snapshot-based data protection
- Organisations expanding storage over time
Consider another model if you need
- You require redundant power supplies
- You need a short-depth rackmount chassis
- You require an x86 processor or built-in M.2 slots
