Blazingly-fast all-flash server aiming for I/O-intensive applications
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.
Dual Intel® Xeon® Silver 8-core with NUMA
DDR4 ECC RDIMM, up to 512GB
Over 240,000 iSCSI 4K random write IOPS
Up to 72 drives with RX2417sas1
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.
Fully certified storage virtualization solutions
Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.
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 overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.
Flexible Shared Folder / User Quota System provides comprehensive quota control on 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
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.
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.
Analyzes system settings, password strength, network preferences, and removes any possible malware.
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 keep data from unauthorized access.
Prevent others from logging in to your DSM by generating a one-time password (OTP) on your mobile device.
Customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered package files.
