RS3617xs+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack Cinder. With VMware vSphere 6 and VAAI integration certified, RS3617xs+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. As the centralized storage of a virtual environment, RS3617xs+ enables virtual machine migration, allowing movement from server to server whilst eliminating service downtime and disruption to user. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improves the efficiency on massive data transfer and migration. With OpenStack Cinder support, RS3617xs+ can be used as a block-based storage component for servers complying with the Cinder API.
Comprehensive Business Applications
Powered by the innovative Synology DiskStation Manager (DSM), RS3617xs+ comes fullyequipped with applications and features designed specifically for large-scale business:
- Easy integration with existing business network environments through Windows AD and LDAP directory services without recreating user accounts.
- Windows ACL support provides fine-grained access control and efficient privilege settings, allowing RS3617xs+ to fit seamlessly into current infrastructure.
- Built-in backup applications protect information assets by regularly backing up files and iSCSI LUNs locally and remotely.
- Continuous data protection with snapshots of shared folders allows restoration of previous versions when the need arises.
- Advanced Encryption Standard (AES) on shared folders with hardware acceleration ensures security without compromising access performance, providing over 2,612MB/s in reading.
RS3617xs+ is designed to grow with businesses and provides the ability to seamlessly expand a single volume up to 108TB (default) / 200TB (with at least 32GB RAM installed) on the fly. RS3617xs+ supports up to 36 HDDs or SSDs for flexible capacity and balanced performance to meet the needs of varying applications and processes. When the storage capacity of RS3617xs+ nears its limit, expansion is easily accomplished with up to two Synology Expansion Unit RX1217/RX1217RP2 via specially-designed connection cables to maximize data transmission throughput between main server and expansion units. Management of the large storage space on RS3617xs+ is simple and flexible. Multiple Volumes on RAID allows users to create more than one volume on a RAID structure, providing a flexible and efficient way to manage the storage across all hard drives. When the need for more space arises, the volume could be easily expanded without any service disruption.
Reliability, Availability & Disaster Recovery
