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.

Feature
Technical Specifications

A straightforward system to replace your aging SAN

The TCO of deploying a storage system shouldn’t be difficult to predict. Synology’s business-grade systems come with a full suite of data protection features and up to 5 years of warranty by default. You can focus on making the most out of your storage instead of worrying about the next maintenance contracts or license fees.

Choose the right storage option to power your virtualized workloads. Both support 10/25/40GbE* interfaces to boost network bandwidth.

All-flash FS series

Deliver the highest IOPS and lowest latency required for running databases and analytics.

Hybrid storage

Leverage SSD cache to provide an optimal balance between performance and storage capacity. *To support 25/40GbE network interface, please check the compatibility list for the supported network interface card.

When the time comes for business expansion or storage consolidation, easily scale up the memory or storage capacity (to up to 180 drives) on the fly without interrupting existing services.

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.

More advanced features

Fast clone

Create near-instantaneous virtual copies of iSCSI LUNs or vDisks on NFS with a simple click.

NFS v4.1 support

Access an NFS server via multiple network connections at the same time and enable higher bandwidth and auto-failover.

Thin provisioning support

Enable IT admins to maximize storage utilization and lower their TCO.

Consolidate your NAS and SAN infrastructure

For remote offices/branch offices that need both a file server and an iSCSI/NFS storage for virtualized workloads, Synology allows them to create NAS and SAN environments on one system, greatly simplifying management and reducing footprints for IT admins.

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.
