All the connectivity options you need

Ample built-in and supported networking options ensure that your applications fully benefit from the speed of all-flash arrays and make the FS2500 easy to integrate in any IT environment.

Built-in connectivity
Leverage fast transfer speeds right out of the box and integrate easily with your existing infrastructure with dual 10GbE and dual 1GbE ports.

Support for 25/40GbE
Enable faster networking with 25 or 40GbE network interface cards, thanks to the PCIe 3.0 expansion slot.

Built to boost service continuity

The FS2500 protects data and services through robust hardware and software safeguards, ensuring access to your digital assets even in the face of disaster.

Dual power supply

Reduce the possibility of power disruptions on a single distribution channel or PDU adversely impacting data and service availability with redundant PSUs.

Modular components

The FS2500 also comes with hot-swappable fans and system trays for easy replacement in case of malfunction.

Automatic failover

Network ports supporting automatic failover eliminate single points of hardware failure, ensuring stable operation at all times.

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.

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.

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.

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.

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.

Fully certified storage virtualization solutions
