Scalability with great performance
The SA6400 can accommodate up to 1.9 PB with support for eight 12-bay RX1223RP expansion units. Direct connections from host to expansion units ensure optimal performance.
- Over 10,000/6,200 MB/s read/write after expansion3
- Up to 8 expansion units
- RX1223RP units directly connect to SA6400
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.Learn more

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.4
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.
Private cloud

A private cloud suite for file sharing
Empower your entire organization with a streamlined ability to access, share, and sync data from anywhere.

Maintain a full overview of file activities and track file share settings changes with detailed records in the Synology Drive Admin Console.Learn more
SMB/NFS implementation at scale
Leverage SMB or NFS protocols to provide efficient access to company files over the local network or VPN. Manage data access privileges with access control lists (ACL) through Active Directory/LDAP integration and protect files against tampering, loss, or removal with built-in snapshot technology.
Cross-site syncing

Secure site-to site file and folder syncing
Make sure branches always have up-to-date copies of crucial documents and data available locally by syncing Synology systems one or two-way using Synology Drive ShareSync. Have files updated across locations each time there is a change to efficiently keep all stakeholders on the same page.Learn more
Efficient cross-site syncing through the cloud
Boost syncing speeds, cut bandwidth use, and reduce your storage footprint by leveraging the powerful connectivity of our data centers. Synology Hybrid Share intelligently synchronizes data to Synology devices.5 Large or less frequently accessed files are stored on the cloud to reduce local storage requirements, while frequently used files are stored on local devices to provide users access at LAN speeds.Learn more
