DS1517+

Synology DiskStation DS1517+ features a quad-core processor with AES-NI hardware encryption engine,

providing outstanding performance even with encryption. Supercharge your storage with the optional

M.2 SSD adapter card for dual SSD cache drives. DS1517+ is the ideal storage solution for centralizing data

backups, protecting critical assets, and sharing les across dierent platforms. Synology DS1517+ is backed

with Synology’s 3-year limited warranty.

High Performance & Easy-to-Scale

Synology DS1517+ is a 5-bay network attached storage solution with great performance
and scalability. DS1517+ is equipped with an Intel quad-core 2.4 GHz processor and
two memory options: 2GB or 8GB, with the exibility to expand up to 16GB for even
more intensive workloads. With dual-channel memory design, it provides outstanding
sequential throughput at over 1,165 MB/s reading and 527 MB/s writing under a RAID
5 conguration with 10GbE Link Aggregation enabled1.

DS1517+ supports up to 15 drives with two Synology DX5172 Expansion Unit attached,
allowing you to start small and easily to scale up on demand. The PCIe slot supports
the optional PCIe M.2 SSD adapter card M2D173 for dual M.2 SATA SSD slots to be
used as SSD cache for greatly enhanced storage performance without using the 3.5"
drive bays. The PCIe slot can also be used to upgrade the DS1517+ with 10GbE network
add-in-cards.

Btrfs: Next Generation Storage

DS1517+ integrates the Btrfs le system, bringing the most advanced storage
technologies to meet the management needs of modern large-scale businesses:

• Flexible Shared Folder / User Quota System provides comprehensive quota control
on all user accounts and shared folders.

• Advanced snapshot technology with customizable backup schedule allows up to
1,024 copies of shared folder backups and 65,000 copies of system-wide snapshots
without occupying huge storage capacity and system resources.

• File or folder level data restoration brings huge convenience and saves time for users
who wish to restore only a specic le or folder.

• File self-healing: Btrfs le system is able to auto-detect corrupted les with mirrored
metadata, and recover broken data using the supported RAID volumes, which include
RAID 1, 5, 6, and 10.

Virtualization Ready

DS1517+ provides seamless storage solutions for virtualization environments,
including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and
VAAI integration certied, DS1517+ helps ooad specic storage operations and
optimizes computation power for unparalleled performance and eciency in VMware
environments. As the centralized storage of a virtual environment, DS1517+ enables
virtual machine migration, allowing movement from server to server whlst eliminating
service downtime and disruption to users. Windows Ooaded Data Transfer (ODX)
and Synology Advanced LUN support greatly improve the eciency of massive data
transfer and migration. With OpenStack support, DS1517+ can be used as a block-based
storage component for servers complying with the Cinder API.

Comprehensive Business Applications

Powered by the innovative Synology DiskStation Manager (DSM), DS1517+ comes
fully-equipped with applications and features designed specically for large-scale
business:

• Windows® AD and LDAP support allow easy integration with existing business directory
services without recreating user accounts.

• Windows ACL support provides ne-grained access control and ecient privilege
settings, allowing DS1517+ to t seamlessly into current infrastructure.

• Application privileges controls access to applications and packages based on each
individual account, user group, or IP address.

• MailPlus allows your business to set up a secure, reliable, and private mail server while
giving your employees a modern mail client for receiving and sending messages

• Powerful collaboration suite with Synology Oce, Calendar and Chat for secure
and high-performance private communications and content organization that your

Virtualization Ready

Synology DS1517+ is an optimized
and certied storage solution for a
various virtualization environments.

Synology Collaboration Suite

Powerful and secure private cloud
solution for business collaboration
and organization with simple but
eective management options.

Robust Scalability

Management of the storage space on DS1517+ is simple and exible. Multiple Volumes
on RAID allows you to create more than one volume on a RAID structure, providing a

exible and ecient way to manage your storage across all available hard drives. When
the need for more space arises, the volume can be easily expanded without any service
disruption. DS1517+ provides the ability to seamlessly expand a single volume up to 108
TB on the y. When the storage capacity of DS1517+ nears its limit, expansion is easily
accomplished with up to two Synology Expansion Unit DX517 to support up to 15
SATA drives.

Reliability & Availability

System reliability is of paramount importance to businesses which depend upon their
commercial servers every day. DS1517+ responds to these concerns with wide-ranging
availability and redundancy features:

• Synology High Availability ensures seamless transition between clustered servers in
the event of server failure with minimal impact on applications.

• Redundant system fans and network ports with failover support ensure continual
service uptime.

• Optional 5-year warranty5 is available in select regions.
