- Scalability : Up to 1.9 PB with 8 x RX1223RP expansion units
- CPU : Over 6,500/4,000 MB/s sequential read/write
- Networking : Optional 25/40GbE or Fibre Channel connectivity
On-demand storage expansion
The SA6400 scales up flexibly whenever your data demands do. Accommodate up to 9 times the original capacity by adding 12-bay RX1223RP expansion units as your deployment grows.
Built for high reliability
The SA6400 is designed with built-in redundancies to keep mission-critical services running, even when disaster strikes.
Out-of-band (OOB) management
Remotely power on/off, force restart, and reset your server, or view real-time and historical DSM system logs, even while the device is powered off or the primary network is down, using the dedicated out-of-band management console.
Redundant power supply
Reduce the possibility of power disruptions on a single distribution channel or power distribution unit adversely impacting data and service availability with redundant PSUs.
Failover cluster
Combine two SA6400 units into a high-availability cluster with Synology High Availability to achieve full hardware and data redundancy. Minute-level failover minimizes data loss and downtime in the event of server failure, or while performing system updates or upgrades.
Advanced networking options
The SA6400 has the flexibility to accommodate different operating environments.
Built-in fast connectivity
Two 10GbE RJ-45 ports provide rapid transfer speeds right out of the box.
Configurable networking options
Add up to 2 extra 10GbE SFP+/RJ-45, 25GbE SFP28, or Fibre Channel ports in varying configurations.2
Failover and network balancing
Bond multiple network interfaces with Link Aggregation to enable automatic network failover and load balancing.
Versatile data storage and business application platform
Provide easy access to business data, consolidate digital assets, or host cost-efficient business solutions.
Flexible file server
Take advantage of the SA6400’s high storage capacity and expansion capability to host large amounts of data on a central repository. Provide user-friendly access to business data and set up powerful cross-site syncing to empower remote and multi-site collaboration.
Central backup server
Back up PCs, servers, Synology systems, SaaS data, and VMs, and back up your backup servers themselves with a scalable central storage solution.
Business application platform
Host cost-efficient business solutions, either through containers, virtual machines, or Synology DiskStation (DSM)’s own solutions, including a powerful free backup suite, a versatile mail server, and a surveillance VMS with transparent licensing.
Centralized monitoring and management
Stay on top of your fleet and keep it in optimal condition with our cloud and DSM-based monitoring and management solutions.
Central Management System (CMS)
Conveniently manage your fleet of Synology systems from a centralized console.
Active Insight
A powerful cloud-based platform for monitoring performance, backup status, login activity and performing lightweight management tasks.
Synology has you covered
The SA6400 is backed by Synology's 5-year limited warranty,6 including technical support and hardware replacement services to maximize your return on investment and ensure continued high-quality performance
