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 flexibility 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 configuration with 10GbE Link Aggregation enabled.
DS1517+ supports up to 15 drives with two Synology DX517 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.
Virtualization Ready
DS1517+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and VAAI integration certified, DS1517+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. As the centralized storage of a virtual environment, DS1517+ enables virtual machine migration, allowing movement from server to server whilst eliminating service downtime and disruption to users. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improve the efficiency 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 specifically 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 fine-grained access control and efficient privilege settings, allowing DS1517+ to fit 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 Office, Calendar and Chat for secure and high-performance private communications and content organization that your organization can easily manage and control.
Robust Scalability
Management of the storage space on DS1517+ is simple and flexible. 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 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 fly. 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 warranty is available in select regions.
