Virtualization Ready
With iSCSI support in DSM, DS916+ provides seamless storage solutions for virtualization
environments, including VMware®, Citrix®, and Hyper-V®. With VMware vSphere 5 and VAAI
integration, DS916+ helps ooad specic storage operations and optimizes computation
power for unparalleled performance and eciency in VMware environments. It is the ideal
alternative to SAN solutions for businesses. Fast and cost-eective, iSCSI allows SMB users to
consolidate storage into data center storage arrays while providing hosts with the illusion of
locally-attached disks.
Easy Backup Solutions
With block-level incremental backup and cross-version deduplication, Synology Hyper
Backup provides multi-version backup with optimized storage utilization and allows
multiple backup destinations to local shared folders, external hard drives, network shared
folders, rsync server, and public cloud services. Synology High Availability Manager ensures
seamless transition between clustered servers in the event of server failure with minimal
impact to applications to decrease the risk of unexpected interruptions and costly downtime.
24/7 Security Solution
Synology Surveillance Station oers a centralized interface to manage IP cameras
deployed in your working environment, allowing users traveling miles away to safeguard
the environment by watching live views, recording events, and taking snapshots with
a computer or mobile device. DS916+ is an ideal surveillance solution as it is capable of
hosting up to 40 IP cameras (30 FPS at 720p). In addition to its intuitive setup and hasslefree interface, Surveillance Station features an optimized live view experience with on-screen
operations, smart analytic tools like motion detection, and an alert system that sends instant
notication through DS cam, SMS, and e-mail.
Energy Efcient and Easy Management Design
Synology DS916+ is designed and developed with energy eciency in mind. Compared with
the average storage server counterparts, DS916+ consumes only 30W in regular operation.
The support of Wake on LAN/WAN and power schedule further reduces power consumption
and operation cost. HDD hibernation can be congured to take eect automatically when
the system has been inactive for a specied period of time. This not only saves energy but
also extends the lifespan of the hard disks.
All Synology products are produced with RoHS compliant parts and packed with recyclable
packing materials. Synology acknowledges the responsibility as a global citizen to
