DiskStation DS2015xs

10GbE-ready NAS for stellar performance and maximum ROI

Benefiting from its built-in 10GbE SFP+ LAN ports, the quad-core Synology NAS offers SMBs ultra-fast performance required for the rigorous data processing and virtualization tasks that our future demands.

DS2015xs

Unparalleled performance within and beyond its tier

Powered by an all-new quad-core CPU and a RAM module expandable to 8GB (coming with 4GB by default), DS2015xs delivers over 1635.12 MB/s throughput. The extraordinary performance far outshines other NAS servers in its price range, and allows DS2015xs to deal with considerable amount of data processing requests from business' critical services.

Built-in 10GbE SFP+ LAN ports and SATA III 6Gb/s support

DS2015xs is equipped with two built-in 10GbE SFP+ ports and two 1GbE RJ-45 ports, entitling productivity-minded SMBs to lightning fast network connection that used to be the privilege of costly enterprise-grade servers. Enabled by Link Aggregation support, the maximized bandwidth can effortlessly handle intensive multi-tasking, such as simultaneously running multiple applications in a virtualized environment. Coming with native SATA III 6Gb/s support, DS2015xs further ensures the optimum data process under heavy system loading.

High reliability with redundancy mechanisms

The four LAN ports with failover support and hot-swappable drives ensure continual service uptime should the drives need replacement or unexpected LAN failure occurs. In addition, DS2015xs’ CPU benefits from a passive cooling design to avoid dependency upon a dedicated processor cooling fan, thus mitigating any critical point of failure. As to its hard drive fans, when the system detects a failure, the built-in redundancy mechanism will spin up the functional fan to properly ventilate the system.

Robust scalability up to 200TB

DS2015xs easily scales up to 20 drives and can be expanded to a maximum 200TB raw capacity by using the DX1215 expansion unit. It securely connects to the Synology DX1215 with specially-designed expansion cable to ensure maximum throughput.

SSD cache technology

DS2015xs enables the combination of hard drives and SSD cache, boosting throughput efficiently while minimizing cost per gigabyte. With full SSD cache support, DS2015xs offers a significant reduction in I/O latency without crippling your budget. With only a small upfront investment, businesses can benefit from significant server performance enhancement.

Fit into business environments easily

With the support of Windows AD, LDAP, and Domain Trust, DS2015xs enables seamless account integration. The User Home feature can automatically create a "home" folder for every user account to minimize the administrator's effort in repeatedly creating "home" folders for all accounts. Windows ACL support on DS2015xs allows IT administrators to fine tune access controls and set up privileges to files and folders on DS2015xs through the familiar Windows user interface. With compatibility for major protocols, DS2015xs can eliminate server configuration overhead and enhance IT administrators’ efficiency. Learn more

Seamless storage solution for virtualization environments

DS2015xs provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® & VAAI integration, DS2015xs helps offload specific storage operations and optimizes computation power in VMware environments. Windows ODX support speeds up data manipulation as the data transfer is offloaded. iSCSI also lets SMB users consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks. Learn more

Unified storage system

DS2015xs enables businesses to cost-effectively manage multi-protocol data by integrating file-level (NAS) and block-level (SAN) storage into one unified storage system. Files can be shared across Windows®, Mac®, and Linux® platforms seamlessly with comprehensive network protocol support (CIFS/SMB, AFP, and NFS). DS2015xs provides a cost-effective iSCSI solution, allowing large scale businesses to consolidate storage into data center storage arrays. With thin provisioning available for file-level iSCSI LUN, you can maximize storage utilization by oversubscribing provisions and grow storage space as needed. Learn more

Protection with LUN backup, snapshot, and clone

DS2015xs enhances the ease of moving and copying data in a virtualized environment with the features LUN Snapshot, clone, and replication. Synology’s LUN Clone and LUN Snapshot only consume 1/1000 of the original size highly optimizing storage usage. In addition, Synology's LUN Snapshot lets you create up 256 snapshots per LUN using point-in-time technology without having any impact on system performance. With better support to servers under VMware vSphere or Windows environment, IT managers can expect guaranteed VM status and data consistency through application-consistent snapshots. Learn more

Synology CMS (Central Management System)

For enterprises with more than one Synology NAS server, CMS offers the flexibility and convenience for IT administrators to manage all of them from a single point of entry. Through a simple interface, you can obtain a clear overview on resource consumption and logs, helping you identify any issue right away. With group policies, CMS can do much more for your daily tasks. Once a NAS joins a group, it will automatically adopt its rules and behave as intended, without extra configuration. Learn more

Increase business productivity with cloud solutions

With comprehensive cloud solutions, DS2015xs lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key. Learn more

Ensuring business continuity & reliability

Uninterrupted availability is a critical goal for all businesses. DS2015xs offers Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. Shared Folder Sync can replicate data in real-time to another Synology NAS at a remote location, giving your business the Recovery Time Objective (RTO) for prompt disaster recovery. With multiple LAN ports, DS2015xs also ensures redundancy in the event of unexpected network failure. Learn more

*Please refer to the SHA White Paper for more details.
