About Synology FlashStation FS6400

Because your data-intensive applications demand uncompromising performance, the FlashStation FS6400 24-Bay NAS Server stands as the pinnacle of reliability and efficiency. This diskless, 2U rackmount server is engineered for the most I/O-intensive and latency-sensitive tasks, making it an impeccable choice for multimedia post-production, virtual machine deployment, online transaction processing, and sophisticated database applications.

Experience high-performance networking with the FS6400's Multi-LAN design, capable of executing Link Aggregation and failover to maintain consistent connectivity. For those environments that require even greater speeds, the server is equipped with two PCIe 3.0 slots, ready to accept optional Ethernet add-in cards for accelerated data transmission.

The Synology FS6400 is not just about speed; it's also about seamless integration with virtual environments. Supporting a wide array of virtualization solutions, including VMware vSphere, Microsoft Hyper-V, Citrix Xen Server, and OpenStack Cinder, this NAS server enhances work efficiency by allowing you to run and manage multiple virtual machines on Windows, Linux, or DSM using the Virtual Machine Manager.

Data protection is revolutionized with the next-generation Btrfs file system, which introduces cutting-edge storage technologies and optimized snapshots to prevent data corruption and minimize maintenance efforts. The system boasts a flexible Shared Folder/User Quota System for comprehensive quota control, Snapshot Replication for schedulable and space-efficient data protection, and file- or folder-level data restoration for swift and flexible data recovery. Automatic file self-healing is another standout feature, detecting and repairing corrupted files without user intervention.

The FS6400 addresses the unique challenges of SSD and RAID technology with RAID F1, a specialized algorithm that distributes workload unevenly across drives, enhancing storage pool resilience and safeguarding your data.

Digital asset protection is paramount, and the FS6400, powered by Synology DiskStation Manager (DSM), offers advanced security measures to shield against data loss and potential vulnerabilities. Security Advisor, AppArmor, AES 256-bit encryption, and 2-step verification work in concert to secure your system settings, network preferences, and data transmissions.

The Synology ecosystem provides additional layers of productivity and security. Synology High Availability ensures a seamless transition between clustered servers in the event of a server failure, while Synology Office, MailPlus, and Virtual Machine Manager offer collaborative tools and virtualization capabilities. Snapshot Replication and comprehensive built-in security tools provide robust data protection and disaster recovery solutions.

With a spacious capacity of up to 108TB, the FlashStation FS6400 is a durable, high-performance, and user-friendly NAS server that stands out in the market for its expansive storage capabilities and the trusted reputation of Synology.
