With 12 HDD trays and support for adding up to two Synology DX1215² expansion units, DS3615xs provides the ability to seamlessly expand up to 216TB³ of raw storage capacity and expand a single volume up to 108TB on the fly. When the storage capacity of DS3615xs nears it limit, expansion is easily accomplished as it supports up to 36 HDDs or SSDs. DS3615xs provides enterprises flexible capacity and balanced performance to meet the needs of varying applications and processes.

 

 

In addition to the default 4 Gigabit ports, DS3615xs comes with one PCI Express Gen3 x8 slot, allowing installation of 10GbE Network Interface Cards (NIC) for maximized bandwidth. Coming with native SATA III 6Gb/s support, DS3615xs ensures the optimum data process under heavy system loading.

 

 

DS3615xs 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, DS3615xs 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.

 

 

 

Synology DS3615xs is backed with Synology's 5-year limited warranty. With technical support and hardware replacement service, the five-year warranty maximizes your enterprises' return on investment. For the entire duration, you will enjoy technical support via e-mail and telephone.

 

 

The Synology Replacement Service (SRS)* provides free shipment of replacement units as early as the next business day. SRS can expedite the process of replacing defective products and minimize service downtime.

With the support of Windows AD, LDAP, and Domain Trust, DS3615xs 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 DS3615xs allows IT administrators to fine tune access controls and set up privileges to files and folders on DS3615xs through the familiar Windows user interface. With compatibility for major protocols, DS3615xs can eliminate server configuration overhead and enhance IT administrators efficiency.

 

 

DS3615xs provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere  5 & VAAI integration, DS3615xs 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.

 

Unified storage system

DS3615xs 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). DS3615xs 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.

 

 

DS3615xs enhances the ease of moving and copying data in a virtualized environment with the features - LUN Backup, LUN Snapshot, and LUN Clone. DS3615xs offers iSCSI LUN backup at storage level without extra charge. Synology LUN Clone and LUN Snapshot only take up 1/1000 of the original size which highly optimizes 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.

 

 

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

 

With comprehensive cloud solutions, DS3615xs lets you create your own cloud easily. Cloud Station is the perfect package to sync files across multiple devices with the benefit of better privacy for important data. Files can be edited in offline mode and later synced to Cloud Station, which retains up to 32 versions to avoid file overwriting. With mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprise, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can customize synchronization rules, such as avoiding syncing large files to optimize bandwidth usage.

 

 

Uninterrupted availability is a critical goal for all businesses. DS3615xs offers Synology High Availability (SHA) technology which 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, DS3615xs also ensures redundancy in the event of unexpected network failure.

 

 

 

DS3615xs provides share-level AES 256-bit encryption to block off unauthorized access attempts. Once you create and encrypt a shared folder, people without the encryption key will not be able to use the encrypted data even if they remove the hard drives from your DS3615xs and mount it on their device. 2-Step verification gives an extra layer of protection as 6-digit one-time code sending to your mobile device is required for login. In addition, DS3615xs provides other security add-ons, such as IP block & allow list, Antivirus packages, firewall, and DoS attack prevention. These enhancements ensures a secure DSM environment.
