DiskStation DS2415+

Ultra-performance NAS optimized for massive storage and encryption

Featuring a quad-core processor, hardware encryption engine, and flawless software integration, DS2415+ is a powerful, expandable 12-bay NAS server that delivers outstanding speed and accelerated data encryption. Easily scalable, the DS2415+ can be equipped with up to 6GB of DDR3 RAM and host up to 240TB of raw capacity with a Synology DX1215 expansion unit.

DS2415+

Quad-core CPU for blazing-fast performance

DS2415+ is powered by a quad-core CPU running at 2.4 GHz. Combined with 2GB of DDR3 RAM (expandable to 6GB), it delivers blazing-fast performance over 451 MB/s reading and 415 MB/s writing. That much power makes it easy for DS2415+ to multitask and provide consistently high throughput to all connected clients.

Fast encrypted data transmission with AES-NI

Encrypting data is essential to a healthy security policy. Equipped with a dedicated hardware encryption engine, DS2415+ is the ideal digital locker for sensitive data; files and folders are encrypted on the fly without any perceived performance loss. DS2415+ delivers encrypted data transmission speeds over 450 MB/s reading and 198 MB/s writing.

Robust scalability up to 24 drives

As your data storage needs grow, DS2415+ can be connected to a dedicated DX1215 expansion unit for additional storage on the fly, growing capacity with minimal effort. With a DX1215 connected through a cable with specially-designed locking connectors, raw capacity can be as high as 240TB.

Quad LAN ports for failover and Link Aggregation support

Equipped with four RJ-45 Gigabit Ethernet ports featuring failover and Link Aggregation support, DS2415+ ensures continual network uptime even if LAN connection malfunction occurs on one port, reducing the chance of service disruption and costly downtime. Link Aggregation improves connection speeds beyond the limits of a single network cable or port.

SSD cache technology

DS2415+ enables the combination of hard drives and read/write-optimized SSD cache, boosting throughput efficiently while minimizing cost per gigabyte. With full SSD cache reading and writing support, DS2415+ 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.

Easy installation, hassle-free maintenance

Easy installation and hot-swappable hard drive support ensures easy maintenance and continuous service uptime should a hard drive need replacement. In addition, DS2415+ incorporates a passive cooling design to reduce dependency on the dedicated processor cooling fan, thus mitigating any critical point of failure. When the system detects a fan failure, the built-in redundancy mechanism ensures continuous operation until the replacement fan arrives.

USB 3.0 ensures speedy transfers to external storage

DS2415+ boasts USB 3.0 ports to connect to various kinds of external storage devices, while ensuring fast and efficient file transfer speeds. Support for USB 3.0 offers transfer speeds of up to 5 Gbps (about 10 times faster than USB 2.0), meaning it takes less time to transfer data to external hard drives, while also consuming less power.

Award winning OS - DiskStation Manager

Synology DiskStation Manager (DSM) is a sleek, browser-based operating system running on every DiskStation and RackStation, which makes managing your Synology NAS a breeze. Featuring an intuitive user interface, DSM makes accessing and sharing your data smarter and simpler. Synology's Package Center lets you download and install useful add-on packages designed specifically for individual or business needs, meaning you can enjoy more entertainment in your life or better productivity at work.Learn more

Seamless storage solution for virtualization environments

DS2415+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® & VAAI integration, DS2415+ 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

Fit into business environments easily

With the support of Windows AD, LDAP, and Domain Trust, DS2415+ 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 DS2415+ allows IT administrators to fine tune access controls and set up privileges to files and folders on DS2415+ through the familiar Windows user interface. With compatibility for major protocols, DS2415+ can eliminate server configuration overhead and enhance IT administrators’ efficiency. Learn more

Optimize storage management

With Synology's Storage Manager, DS2415+ allows for flexible storage deployment and utilization. You can optimize RAID configuration with Synology Hybrid RAID (SHR) while providing redundant data protection. Other features such as multiple volumes on single RAID and Global Hot Spare also greatly enhance management efficiency and fit deployment of any kind. 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

Ensuring business continuity

Uninterrupted availability is a critical goal for all businesses. DS2415+ supports Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. The Heartbeat mechanism detects regular "heartbeats" between the two servers. If the main server encounters unexpected downtime, the passive server immediately takes over. With multiple LAN ports, DS2415+ also ensures redundancy in the event of unexpected network failure. Learn more

Your backup plan, better than ever

Hyper Backup allows for backing up data on DS2415+ to a wide variety of destinations, including another Synology NAS, rsync-compatible server, or cloud storage services. With block-level incremental backup and cross-version deduplication, Hyper Backup minimizes the storage required while still preserving as multiple recovery points. Learn more

Secure your data

DS2415+ offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, DS2415+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention. Learn more
