Redundancy first
Availability and protection
Synology High Availability (SHA)
Enable automatic minute-level failover by pairing up two FS2500 units to create a high-availability cluster, minimizing service downtime in the event of a server failure. Learn more
Snapshot Replication
Create point-in-time snapshots of LUNs and shared folders with an RPO as low as 5 minutes, with support for granular version control. Learn more
Hyper Backup
Back up files, LUNs, applications, and system configurations on your NAS to other Synology NAS, Synology C2 Storage, public cloud platforms, USB devices, file servers, or local folders. Learn more
Flash volume deduplication
Leverage volume-wide deduplication to remove duplicate data on all-flash arrays and greatly increase storage efficiency. Eliminate redundant data to save up to 65% of storage space use in applications like virtual desktop infrastructure and virtual machines.
Complete virtualization platform
Deploy the FS2500 as fast and efficient VM storage and benefit from free native hosting, management, and protection tools in Synology DiskStation Manager (DSM).
Certified storage for VMs and containers
Deploy and facilitate storage operations in various virtualization environments with full certification for VMware® vSphere™, Microsoft® Hyper-V®, Citrix® XenServer™, and OpenStack, and a Kubernetes CSI driver for integrated volume management.
VM and container storage on all-flash arrays can benefit from volume-wide data deduplication, a technology that removes identical data to optimize storage use.
Alternative VM host for testing and recovery
Synology Virtual Machine Manager (VMM) is a hypervisor for Windows® and Linux® VMs or Virtual DSM, a virtualized version of DSM.4 Use your Synology device as an alternative host for VMs to quickly recover services following failure or run failover copies of PCs, servers, and VMs created with Active Backup for Business (ABB), DSM’s data protection tool for physical and virtual environments.
Streamlined configuration and administration
Manage storage directly from your hypervisor with Synology Storage Console for VMware® or Windows platforms, provision volumes directly from the Kubernetes CLI, and offload storage operations and speed up data transfer through VMware® VAAI integration and Windows ODX.
