Features
Uncompromising performance
Synology FlashStation FS6400 is a 2U rackmount server designed for I/O-intensive and latency-sensitive tasks, ideal for multimedia post-production, virtual machines, online transaction processing, or database applications.
- CPU: Dual Intel® Xeon® Silver 8-core with NUMA
- Memory: DDR4 ECC RDIMM, up to 512GB
- High Performance: Over 240,000 iSCSI 4K random write IOPS
- Scalability: Up to 72 drives with FX2421
Fast and reliable networking
With multi-LAN design, FS6400 is capable of performing Link Aggregation and failover. For environments requiring a higher speed, two optional Ethernet add-in cards can be installed on PCIe 3.0 slots to provide fast data transmission.
Complete iSCSI and virtualization solutions
Synology iSCSI storage supports most virtualization solutions such as VMware vSphere, Microsoft Hyper-V, Citrix Xen Server, and OpenStack Cinder to enhance work efficiency. You can run and manage multiple virtual machines on Windows, Linux, or DSM using Virtual Machine Manager.
Next-generation file system for better data protection
The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overheads. It offers flexible, efficient data protection and recovery tools while ensuring high-level data integrity.
- Flexible Shared Folder/User Quota System provides comprehensive quota control on all user accounts and shared folders
- Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots
- File- or folder-level data restoration accelerates data recovery and provides more flexibility for businesses
- Automatic file self-healing detects and recovers corrupted files without user intervention
RAID F1
Due to the peculiarities of SSD and RAID technology, a common challenge lies in how to prevent all of the drives from failing at the same time because of the evenly distributed workload. RAID F1 alleviates this problem with a specially designed algorithm to unevenly distribute workload to drives, enhancing the resilience of the storage pool and ensuring your data remains safe.
Flash volume deduplication
Remove duplicate data on all-flash arrays with volume-wide deduplication to greatly increase storage efficiency. Eliminate redundant data to save up to 65% in storage space use in applications like virtual desktop infrastructure, and virtual machine.
Digital asset protection
Powered by Synology DiskStation Manager (DSM), Synology NAS offers advanced security measures to protect against sudden data loss and potential security holes.
Security Advisor
Analyze system settings, password strength and network preferences, and remove any possible malware.
AppArmor
A kernel-level enhancement that blocks malicious programs from accessing unauthorized system resources.
AES 256-bit encryption
Encrypt shared folders and network data transmission to avoid unauthorized data access.
2-step verification
Prevent others from logging in to your DSM by generating a six-digit one-time password (OTP) on your mobile device.

Notes
Surveillance Station 9.1.3 or above is required to support the maximum IP cameras and FPS figures listed.
Performance figures are obtained from testing conducted with the device fully populated with drives, with their default memory configuration, and under a continuous recording setup. Actual system capabilities may vary based on configuration, drive performance, enabled features, and the presence of additional workloads.
Use NVR Selector to quickly find a suitable model based on your requirements.
The maximum number of camera stream outputs is 2 times the suggested maximum number of IP cameras.
