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.
Redundancy first
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.
