Storage for Virtualization

The storage platform that just works: with the performance, scalability, and integration you’re looking for, built-in data protection functionality, and the ability to consolidate virtualized workloads and file services – all at a one-time hardware cost.

A straightforward system to replace your aging SAN

Seamless integration into virtualization environments

Certified by VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack Cinder, the platform supports both iSCSI and NFS protocols, and integrates with VMware VAAI and Microsoft ODX, ensuring deployment flexibility and facilitating storage operations in a virtualized environment.

VAAI Benefits

  • Faster VM performance is achieved by offloading cycles from ESXi to the storage array.
  • More effective utilization of storage arrays delivered by virtual machines with VAAI support.
  • Better flexibility in deploying and migrating VMs. Higher storage performance and efficiency with VMFS-5 file system.
  • Smoother access and management with load balancing automation in Storage vMotion.

Windows ODX integration

By leveraging ODX, the speed for data manipulation increases dramatically. Since the data transfer is offloaded, the CPU usage of the host server and the network bandwidth utilization shrink to minimum values, which allows the server to handle more important tasks. Compatibility

Enhanced manageability for VMware/Windows

With the plugins and packages Synology has developed for VMware and Windows, administrators are capable of managing their virtual environments efficiently.

VMware/Windows

Synology Snapshot Manager

Install Synology Snapshot Manager for VMware or Windows to create application-consistent snapshots in DSM.

VMware

Support for VMware Site Recovery Manager

VMware Site Recovery Manager allows users to enable disaster recovery directly via VMware vCenter Server, simplifying complicated configurations and optimizing the process.

Windows

Synology SMI-S Provider for SCVMM

The optimization with Microsoft's System Center Virtual Machine Manager (SCVMM) allows an IT administrator to manage multiple Synology NAS servers as storage nodes via SCVMM's centralized user interface.

Built-in data protection

All Synology’s storage systems include comprehensive data protection features to safeguard your virtual environment from disasters – each designed for different RPO/RTO requirements; all of them license-free.

Customer stories

See how these organizations achieved more with Synology.

The storage array has been proven to be more than capable of going toe-to-toe with what would be classed as an enterprise-class all flash array for a fraction of the cost.

FlashStation FS2017 is the ideal storage solution for operating load-critical VMs. As a high-availability cluster with a 5-year warranty and free Synology Replacement Service, the price-performance ratio in this storage dimension is perfect.

With the FS2017 and the RX2417sas expansion unit, we were able to optimize the work efficiencies of over 8,000 employees in all our branch offices.
