Quad-core CPU for blazing-fast performance
DS1515+ 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 450.77 MB/s reading and 396.5 MB/s writing.1 That much power makes it easy for DS1515+ 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, DS1515+ is the ideal digital locker for sensitive data; files and folders are encrypted on the fly without any perceived performance loss. DS1515+ delivers encrypted data transmission speeds over 448.71 MB/s reading and 191.12 MB/s writing.
Quad LAN ports for failover and Link Aggregation support
Equipped with four Ethernet ports featuring failover and Link Aggregation support, DS1515+ 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.
Robust scalability up to 150TB
As your data storage needs grow, DS1515+ can be connected to dedicated DX513 expansion units2 for additional storage on the fly, growing capacity with minimal effort. With two DX513 expansion units connected through specially designed eSATA connectors, raw capacity can be as high as 150TB3.
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, DS1515+ 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 and eSATA ensure speedy transfers to external storage
DS1515+ boasts USB 3.0 and eSATA 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.
Seamless storage solution for virtualization environments
DS1515+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® & VAAI integration, DS1515+ 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.
Fit into business environments easily
With the support of Windows AD, LDAP, and Domain Trust, DS1515+ 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 DS1515+ allows IT administrators to fine tune access controls and set up privileges to files and folders on DS1515+ through the familiar Windows user interface. With compatibility for major protocols, DS1515+ can eliminate server configuration overhead and enhance IT administrators’ efficiency.
Optimize storage management
With Synology’s Storage Manager, DS1515+ 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.
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.
Ensuring business continuity
Uninterrupted availability is a critical goal for all businesses. DS1515+ 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, DS1515+ also ensures redundancy in the event of unexpected network failure.
Effective backup solution
Synology DS1515+ can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station Backup. Whenever you modify a file, the changes are backed up to DS1515+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS1515+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. Synology Hyper Backup allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.
Increase business productivity with cloud solutions
With comprehensive cloud solutions, DS1515+ 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.
Secure your data
DS1515+ 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, DS1515+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.
