Synology® launches highly scalable SA6400 to build the ultimate private cloud for business

Taipei, Taiwan—18 January 2023—Synology today announced the availability of the 12-bay SA6400, its most versatile general-purpose storage system designed to provide enterprises and large studios with lightning-fast data transfer speeds and on-demand capacity expansion.

"SA6400 is the ideal solution to tackle today's ever-increasing amounts of unstructured data," said Julien Chen, Product Manager at Synology. "Its ability to quickly scale as data demands grow makes it suitable to serve as file or backup storage in agile and dynamic environments, getting businesses ready for future data growth."

Class-leading scalability and performance

Storage capacity is seamlessly expandable by adding up to 8 RX1223RP expansion units for a total of 108 drive bays, making room for over 1.9 petabytes on a single system — 9 times the original capacity.

With a throughput of over 6,500/4,000 MB/s sequential read/write,1 SA6400 ensures smooth operations even in the most demanding scenarios, including enterprise data centers, large production studios, and applications in the retail or hospitality sectors.

Performance can be further boosted to accommodate more streams or tackle specialized applications by upgrading the built-in 10GbE networking to 25 or even 40GbE.2

Flexible file serving for growing teams

Comprehensive support for file and block protocols enables large-scale access to company resources over the local network or VPN, with management of access privileges made easy by Active Directory/LDAP integration.

The cross-platform Synology Drive file management and sharing solution enables organizations to create a private cloud that teams can leverage to access, edit, and share files securely, with granular permission settings for maximum security and compliance.

Integration with the cloud — either Synology's own C2 Storage or third-party cloud service providers — allows for efficient cross-site file synchronization for distributed teams or companies adopting hub-spoke organizational models.

Centralized data protection for the entire infrastructure

Keeping critical data and services protected and available is more necessary than ever with continuous and emerging cybersecurity threats.

Synology's suite for endpoint protection, Active Backup Suite, enables Windows, Linux, and macOS (coming soon) devices, Hyper-V/VMware VMs, and Microsoft 365/Google Workspace accounts to be safely backed up onto the SA6400 and quickly restored when needed.

SA6400 also includes data backup, snapshot, and replication automation services to protect shared folders and LUNs, with destinations that range from other Synology systems to the cloud for simple compliance with the 3-2-1 backup rule.

Service availability can be boosted with the Synology High Availability (SHA) service, which pairs identical units to create an active/passive cluster that ensures automatic service failover within minutes in case of unexpected downtime.

Powerful and versatile business application platform

A host of cost-efficient solutions are available through Synology DSM's own download center, containers, or virtual machines.

Built-in business applications include a complete suite of file management and productivity tools that teams can leverage to boost collaboration, as well as a private mail solution with 100% data ownership and a full-featured messaging platform for more convenient and secure communications.

Docker containers and VMs can be run on SA6400 using Docker or Synology Virtual Machine Manager (VMM) — a hypervisor for virtualized versions of Windows®, Linux®, and DSM — to safely test and evaluate applications. Learn more
