Description
The FlashStation FS6400 is a highly reliable and extremely powerful pure flash server for I/O-intensive applications with the lowest possible latency, such as multimedia post-processing, virtual machines, online transaction processing or database processing.
Performance without compromise
The Synology FlashStation FS6400 is a 2HE server for rack mounting, specially developed for I/O-intensive tasks with the lowest possible latency. Equipped with two Intel® Xeon® Silver processors with NonUniform Memory Access (NUMA) I/O optimization, 24 slots for 2.5" SAS/SATA SSDs, and 32 GB DDR4 ECC RDIMM, the FS6400 delivers over 240,000 iSCSI 4K random write IOPS, making it ideal for multimedia editing, virtual machines, processing
Online transactions or database applications. The FS6400 is equipped with two 10GBASE-T ports and supports the installation of optional network cards for data transmission at the highest speed. The storage capacity can be flexibly scaled up to 72 drives with the Synology RX1217sas/RX2417sas expansion unit.
Btrfs: Next-generation storage efficiency
Using the Btrfs file system, the FS6400 provides the latest storage technologies to meet the needs of today's businesses:
Advanced snapshot technology provides predictable, near-instant protection for data in shared folders and iSCSI LUNs.
File-level and folder-level data recovery is extremely convenient and saves time when restoring only a specific file or folder.
A flexible folder sharing and user quota system provides comprehensive quota control for all user accounts and shared folders.
File self-repair : The Btrfs file system can automatically detect corrupted files using mirrored metadata and recover corrupted data using the supported RAID volumes, including RAID 1, 5, 6, 10, and Synology RAID F1.
Applications designed for business
With the innovative Synology DiskStation Manager (DSM), the FS6400 offers a complete range of applications especially for large companies:
Windows® AD and LDAP allow easy integration with existing enterprise directory services.
Windows ACL support provides granular access control and efficient permission settings to seamlessly integrate the FS6400 with your existing infrastructure.
Access to Internet files is simplified by the encrypted FTP server and the web-based file explorer Synology File Station. HTTPS, firewall and automatic IP blocking guarantee that the exchange of files over the Internet is protected with a high security level.
Application permissions control access to applications and packets based on individual accounts, user groups, or IP addresses.
Easy virtualization
Synology iSCSI storage offers full support for most virtualization solutions and an easy-to-use management interface to further increase work efficiency. VMware® vSphere 6.5 and VAAI integrate to offload storage operations and optimize compute efficiency. Windows Offloaded Data Transfer (ODX) accelerates data transfer and data migration and thanks to OpenStack® Cinder support, your Synology NAS can also be used as block-based storage component.
Synology Virtual Machine Manager adds unlimited functionality to your NAS. This allows you to set up and run multiple virtual machines using Windows, Linux, and Virtual DSM to test new software versions in a sandbox environment, isolate your customers' machines, and increase the flexibility of your FS6400 while reducing hardware deployment and maintenance costs.
Reliability, Availability & Disaster Recovery
The reliability of IT systems is critical to organizations everywhere. The FS6400 meets these requirements with comprehensive availability and redundancy features:
Synology High Availability ensures a seamless transition between cluster servers with minimal impact on applications and ensures that your services are available even in unexpected emergencies.
Snapshot Replication provides predictable, near-instant data protection, ensuring that business documents are securely available in shared folders, virtual machines in iSCSI LUNs, or docked application data, even in the event of a disaster.
Redundant power supplies, system fans, and network ports with failover support ensure continuous service availability.
The highly reliable system design with a CPU heat sink without fan and passive cooling technology prevents single points of failure.
DDR4 ECC RDIMM reduces power consumption and has error detection and correction functions during data transmission.
A powerful collaboration solution
Use the productive applications on your Synology NAS to set up your private cloud and improve the collaboration and productivity of your teams.
With Synology Drive you can access data on the Synology NAS via a uniform portal and synchronize data cross-platform. Install the online editor Synology Office and work together on documents, spreadsheets and slides.
With Synology MailPlus you can set up a private and reliable e-mail server with high availability in your company and offer your employees an intuitive web-based client, in order to manage e-mails easily and increase the productivity.
Synology Calendar makes it easy to manage team schedules and daily tasks. Scheduling information can also be synchronized with your CalDAV clients, so you can control your schedules anytime, anywhere.
Synology Chat is a web-based application with which you can start conversations immediately and securely. It also streamlines enterprise communications with powerful information management and interaction capabilities.
