High Performance

The Synology DS411+II is designed for business users who require a reliable storage solution and demand high-performance for file sharing. The Synology DS411+II delivers an average 110.73 MB/sec reading and 105.48MB/sec writing speeds under RAID 5 configuration in a Windows^® environment.

Easy Setup and Management

For users who are limited on time or may not be familiar with configuring complicated routers, the Synology EZ-Internet Wizard simplifies the process of allowing access to the Synology DS411+II from the Internet. The EZ-Internet Wizard walks the user through all of the settings required including firewall settings, port-forwarding, PPPoE setup and DDNS registration for a hassle-free solution to remote access.

Running on AJAX technology, DiskStation Manager’s UI is intuitive and easy-to-use. To save time and minimize redundancy, common tasks are automated, such as creating private shared folders for a large number of users with the User Home feature. Sub-folder privilege settings further extend the flexibility to allocate permissions to different workgroups.

Flexible RAID Management

The Synology Hybrid RAID (SHR) automatically builds an optimal RAID volume with data protection based on the hard drives installed, eliminating the need to have hard drives of identical size, while still offering a manual setup option for advanced users.

Multiple Volumes on RAID allows you to create more than one volume on a RAID structure, providing a flexible and efficient way to manage your storage across all available hard drives. When the need arises to expand the volumes, simply allocate more storage space on the UI, and DSM does the rest for you without any service disruption.

Complete Backup Solutions

The Synology DS411+ offers a centralized backup target to consolidate fragmented and unstructured data across the network. Integrating easily into a current network structure and compatible with Windows^®, Mac^®, and Linux systems, the DS411+ provides the entire office data redundancy and protection. PC Users can back up their data to the Synology DS411+ using the free Synology Data Replicator software, while Mac OS X users enjoy native Apple^® Time Machine^® integration. A backup wizard is also provided for backing up data in the DS411+ to another Synology DiskStation or any rsync server via an encrypted transmission, or to an external hard drive via USB or eSATA connection. Furthering options, the wizard also makes it easy to backup to the cloud via Amazon^® S3.

Full-featured Business Applications

The Synology DS411+II runs on the renowned operation system, Synology DSM, offering applications and features designed specifically for SMBs. Comprehensive network protocol support assures seamless file sharing across Windows, Mac, and Linux platforms. Windows ADS integration allows the Synology DS411+II to quickly and easily fit in an existing business network environment with no need to recreate user accounts.

Windows ACL support on DS411+II provides much finer-grained access control and efficient privilege settings, allowing IT staffs to set up privileges to files and folders on DS411+II through their familiar Windows user interface. The privileges set on Windows ACL will be applied to all access entries, including AFP, FTP, File Station, NFS and WebDAV. The secure privilege offers IT staff peace of mind, no worries about any loopholes.

Internet file access is simplified with the included encrypted FTP server and the web-based file explorer, Synology File Station. HTTPS, the built-in firewall, and IP auto-block support ensure file sharing over the Internet is protected at a high security level.

A wealth of additional features allows the Synology DS411+II to replace several pieces of network hardware. Synology Web Station with support for PHP/MySQL content allows for the hosting of up to 30 websites on a single Synology DS411+II. Synology Surveillance Station offers a centralized interface to safeguard the office environments by deploying IP cameras throughout the network. The built-in mail server turns a Synology DS411+II into a dedicated mail service provider and the USB printer sharing capability minimizes businesses’ printing cost by sharing printing resources throughout the office.

Using the NFS protocol or iSCSI target support within DiskStation Manager, the Synology DS411+II provides seamless serving with Windows, Linux, or Virtual Machine Servers.

Energy Efficient Design

Synology DiskStations are designed and developed with energy efficiency in mind. Compared with the average PC counterparts, the Synology DS411+II consume relatively low amount of power at 41.8 watts only in operation. The support of Wake on LAN/WAN, scheduled power on and off and hard drive hibernation can further reduce power consumption and operation cost.

All Synology products are produced with RoHS compliant parts and packed with recyclable packing materials. Synology acknowledges the responsibility as a global citizen to continually work to reduce the environmental impact of every product produced.
