FS6400

FlashStation FS6400

Blazingly-fast all-flash server aiming for I/O-intensive applications

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 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

 
File- or folder-level data restoration accelerates data recovery, providing 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.

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.
