With two DX513 connected through cables with specially-designed locking connectors, raw capacity can be as high as 120TB3. Reliable redundancy mechanisms DS1515 comes with four LAN failover support to ensure continual network service in case of LAN failure, while the hot-swappable design facilitates easy and risk-free hard drive replacement. The hard drive tray lock design further secures your hard drives from unauthorized or accidental withdrawal. 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. 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. All-in-One server Offering rich office applications, DS1515 can serve as your multi-function server. With add-on packages Mail Server and Mail Station, DS1515 can become a dedicated mail server, and let you enjoy complete webmail service. DS1515 can become a VPN server or VPN client. The comprehensive VPN service let you access resources remotely while maintaining security protocols. As a printer server, DS1515 minimizes businesses' operating costs by sharing printing resources throughout the office. Administration and network tools, such as DNS Server, Directory Server, RADIUS Server, DHCP Server, and Log Center help you manage IT deployment and policies more efficiently. Maximize resource utilization with DS1515! 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. 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. "Backup & Replication" 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.
