Overview
SA3400D
Keep services online with efficient high-availability storage
High-availability file and block storage solution
Accessible and convenient
Maintain data availability with an active-passive high availability dual-controller module
Versatile applications
Manage, distribute, and protect data, back up endpoints, and guard physical premises
Fast and efficient
Over 3,500/2,900 MB/s seq. read/write throughput2 and over 500 TB maximum storage capacity
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.7
Add storage capacity on demand
Scale server capacity up to 576 TB8 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.9 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.10
Performance backed by Synology drives
Engineered to handle intensive workloads, Synology hard drives consistently deliver top-grade performance.
