4-Bay Multi-Gigabit Tower NAS
QNAP TS-431X3-4G Multi-Gigabit NAS
A four-bay tower NAS with an AnnapurnaLabs Alpine AL314 quad-core processor, 4 GB DDR3 memory, one 10GbE SFP+ port, one 2.5GbE port and one Gigabit Ethernet port.
Four-bay storage with three tiers of network connectivity
The QNAP TS-431X3-4G combines four hot-swappable SATA bays with 10GbE SFP+, 2.5GbE and Gigabit Ethernet connectivity. Backup and synchronisation, snapshots, Docker and LXC containers, Qfiling automation and VJBOD support shared storage, collaboration and recovery planning for small and medium organisations.
Key features and benefits
10GbE SFP+ built in
A dedicated 10GbE SFP+ port supports bandwidth-intensive transfers.
2.5GbE and Gigabit RJ45
Separate 2.5GbE and Gigabit ports offer practical connection choices for existing and upgraded networks.
Backup and synchronisation
Hybrid Backup Sync supports backup and synchronisation with other NAS, servers and cloud storage.
Snapshot protection
Snapshots record system status and data to assist recovery after accidental deletion or malware incidents.
Docker and LXC containers
Container support enables application services to run across the NAS and connected environments.
Automated organisation and VJBOD
Qfiling can automate file organisation, while VJBOD can expand another supported QNAP NAS.
