High Performance
The Synology DS211+ is designed for business users who
require a reliable storage solution and demand high-performance for file
sharing. The Synology DS211+ delivers an average 108MB/sec reading and
55MB/sec writing speeds under RAID 1 configuration in a Windows
environment.
Full-featured Business Applications 
The Synology DS211+ runs on the renowned operating system, Synology
DiskStation Manager ( 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 DS211+ to
quickly and easily fit in an existing business network environment with
no need to recreate user accounts. Windows ACL support provides much
finer-grained access control and efficient privilege settings, allowing
users to enjoy native Windows experience.
Internet file access is simplified with the included encrypted FTP
server and the web-based file explorer, Synology File Station 3. 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 DS211+ 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 DS211+. Synology Surveillance Station offers a
centralized interface to safeguard the office environments by deploying
IP cameras throughout the network. The Mail Station add-on turns a
Synology DS211+ into a mail server with only few steps of installation
and the USB printer sharing capability minimizes businesses’ printing
cost by sharing printing resources throughout the office.
With the NFS protocol or iSCSI target support in DSM,
the Synology DS211+ provides a seamless storage solution for with
Windows, Linux, or virtualization servers.
Complete Backup Solutions 
The Synology DS211+ 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 DS211+ provides the entire office data redundancy and
protection. PC Users can back up their data to the Synology DS211+
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 DS211+ 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. In addition, users can back up and restore
DiskStation shared folders in multiple versions using Synology Time
Backup package.
USBCopy and SDCopy provide a plug-n-save solution to
store data. With just one touch on the «Copy» button in the front panel,
it quickly backs up all data on an USB storage device or SD card to the
pre-defined shared folder on the DiskStation.
Peace of Mind with Data Encryption 
The Synology DS211+ is equipped with an encryption engine which
offloads the encryption calculation task away from the main CPU, helping
to improve file transfer speeds of the DiskStation. The Synology
testing lab shows that the hardware encryption engine boasts read speed
that is about 200% faster than the pure software encryption.1
Data protection is an important matter for businesses of
all sizes. High-end features previously available only on enterprise
level hardware are now accessible via the DS211+ to small and
medium-sized businesses. DiskStation Manager ( DSM ), standard on all
Synology DiskStations, provides share-level AES 256-bit encryption to
aid in the prevention of unauthorized access attempts to the hard
drives.
Easy Setup and Management 
Synology DSM operating system offers intuitive and easy-to-use web
experience. For users who are limited on time and not familiar with
configuring complicated routers, the Synology EZ-Internet Wizard
simplifies the process of setting up access to the Synology DS211+ from
the Internet. The EZ-Internet Wizard steps through all of the settings
including firewall settings, port-forwarding, PPPoE setup and DDNS
registration.
The multitasking web UI on DSM lets users to run
multiple applications simultaneously on one tab browser and switch
between them instantly. User Home feature makes creating private shared
folders for a large number of users an easy task as it minimizes the
steps and time for the administrator to create private shared folders.
Sub-folder privilege settings further extend the flexibility to allocate
permissions for different workgroups. All of these features are
performed in a web browser, akin to a full desktop experience.
Energy Efficient with Cool and Quiet Design 
Synology DS211+ comes with the brand new hardware design with energy
efficiency in mind. Not only does it provide the smart airflow to keep
the system running cool 24/7, its 92mm fan and the snap-on HDD tray
cover also allows the system to operate in a completely quiet
environment. DS211+ consumes relatively low amount of power at 24 watts
only in operation compared to PC counterparts. The support of multiple
scheduled power on/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. Hardware
