Built-in High Availability Keep file sharing services, block storage, backups, and other office applications online with automatic minute-level failover. Defend against operational disruptions with two independent and hot-swappable controllers operating in an active-passive configuration.
Made for demanding environments The SA3400D is engineered to provide outstanding performance in both NAS and SAN storage roles. Its throughput and random I/O performance support efficient SMB and NFS file serving as well as a range of iSCSI and Fibre Channel block storage applications.
Consolidate your data infrastructure Manage, protect, and share data with versatile business solutions. Empower team collaboration, sandbox applications, and provide VM storage on a unified platform.
Flexible options to meet changing needs Flexibly scale storage capacity, optimize I/O performance, and meet different network needs with a range of expansion options.
Add storage capacity on demand Scale server capacity up to 576 TB7 when your data storage needs increase by adding two 12-bay RXD1219sas expansion units.
Boost network and I/O performance Add 10/25GbE connectivity with optional add-in cards.8 Create all-flash storage volumes with SAS SSD for lightening-fast I/O, or boost IOPS and cut down latency on HDD volumes by creating SAS SSD read/write cache volumes.
Performance backed by Synology drives Engineered to handle intensive workloads, Synology hard drives consistently deliver top-grade performance.
