Next-Generation File System

A modern le system designed to address obstacles
often encountered in enterprise storage systems,
safeguarding data integrity through metadata
mirroring, self-healing and snapshot replication.

Uncompromising Performance

Synology FlashStation FS6400 is a 2U rackmount server designed for

I/O-intensive and latency-sensitve tasks. Featuring two Intel® Xeon®

Silver processors with Non-Uniform Memory Access (NUMA) I/O

optimization, 24 drive bays supporting 2.5" SAS/SATA SSD, and 32GB

DDR4 ECC RDIMM, FS6400 provides over 240,000 iSCSI 4K random

write IOPS and is ideal for multimedia post-production, virtual machines,

online transaction processing, or database applications.

FS6400 comes with two 10GBASE-T ports and supports optional network

interface cards for high-speed data transmission. Storage capacity

can be further scaled up with Synology expansion unit RX1217sas/

RX2417sas, providing up to 72 storage drives with elastic expandability.

5-year product warranty guarantees hardware replacement and

technical support services, maximizing your return on investment (ROI).

Btrfs: Next Generation Storage Efficiency

FS6400 introduces the Btrfs file system, bringing the most advanced

storage technologies to meet the management needs of modern

businesses:

• Advanced snapshot technology provides schedulable,

near-instantaneous data protection of shared folders and iSCSI LUNs.

• File and folder level data restoration brings huge conveniences

and saves time for users who wish to restore only a specific file or

folder.

• Flexible shared folder and user quota system provide

comprehensive quota control on all user accounts and shared

folders.

• File self-healing: Btrfs file system is able to auto-detect corrupted

files with mirrored metadata and recover broken data using the

supported RAID volumes, which include RAID1, 5, 6, 10, and Synology

RAID F1.

Enterprise-Grade Applications

Powered by the innovative Synology DiskStation Manager (DSM), FS6400

comes fully-equipped with applications and features designed specifically

for large-scale businesses:

• Windows® AD and LDAP support allows easy integration with

existing business directory services.

• Windows ACL support provides fine-grained access control and

efficient privilege settings, allowing FS6400 to fit seamlessly into

existing infrastructure.

• Internet file access is simplified by the encrypted FTP server and

the web-based file explorer Synology File Station. HTTPS, firewall,

and IP auto-block support ensures file sharing over the Internet is

protected with a high level of security.

• Application privileges control access to applications and packages

based on each individual account, user group, or IP address.

Effortless Virtualization Deployment

Virtual Machine Manager

Virtual Machine Manager implements various
virtualization solutions, allowing you to manage
multiple virtual machines on your FS6400, including
Windows, Linux, and Virtual DSM.

Synology iSCSI storage fully supports most virtualization solutions to

enhance work efficiency with a simple management interface. VMware®

vSphere 6.5 and VAAI integration helps offload storage operations and

optimizes computation efficiency. Windows Offloaded Data Transfer

(ODX) speeds up data transfer and migration rates, while OpenStack®

Cinder support turns your Synology NAS into a block-based storage

component.

Synology Virtual Machine Manager adds boundless capabilities to

your NAS. Set up and run various virtual machines, including Windows,

Linux, and Virtual DSM, so that you can test new software versions in a

sandbox environment, isolate your customers' machines, and increase

the flexibility of your FS6400 with reduced hardware deployment and

maintenance costs.

Reliability, Availability & Disaster Recovery

System reliability is critical for businesses everywhere. FS6400 responds

to these concerns with wide-ranging availability and redundancy

features:

• Synology High Availability ensures seamless transitioning between

clustered servers in the event of unexpected disasters and ensures

that your services remain online.

• Snapshot Replication provides schedulable, near-instantaneous

data protection, ensuring business documents in shared folders,

virtual machines in iSCSI LUNs, or dockerized application data remain

safe and available in the event of a disaster.

• Redundant power supplies, system fans and network ports with

failover support ensure continual service uptime.

• High reliability system design, including fan-less CPU heat-sink and

passive cooling technology, prevents single points of failure.

• DDR4 ECC RDIMM reduces power consumption and has error

detection and correction capabilities during data transmission.

A Powerful Collaboration Solution

Use the collaboration suites on your Synology NAS to build a private

cloud to enhance team cooperation and boost productivity.

• Synology Drive allows you to access the data and files on Synology

NAS through a unified portal and enable data synchronization across

platforms. You can also install the online editor Synology Office and

collaborate with others on Documents, Spreadsheets, and Slides.

• Synology MailPlus allows your business to set up a private and

reliable mail server with the support of high-availability design and

gives your employees an intuitive web-based client to manage emails

and boost productivity.

• Synology Calendar enables you to manage team schedules and

organize daily tasks effortlessly. Event information can also be

synced to your CalDAV clients, allowing you to check schedules

anywhere and anytime.

• Synology Chat is a web-based application that allows you to start

conversations instantly and safely and optimizes companies’ internal

communications with its powerful information management and
