Synology demonstrated the resiliency of its PAS7700 all-NVMe enterprise storage system by simulating a hardware failure during a live file transfer. The demonstration highlighted the system's active-active architecture and the company's policy of avoiding feature-gating through additional licensing.
The demonstration of the PAS7700 highlights a shift toward high-availability storage that prioritizes service continuity for data-heavy streaming and virtualization environments. By utilizing an active-active setup, Synology eliminates the latency spikes often seen during traditional failovers, which is critical for maintaining stable backend delivery. Furthermore, the company's refusal to feature-gate advanced capabilities like synchronous replication puts pressure on incumbent vendors who rely on per-feature licensing fees. This approach lowers the total cost of ownership for scaling data centers. Watch for the upcoming release of Synology's native object storage tiering to see how it integrates with existing NVMe stacks.
Synology officially announced general availability of the PAS7700 on May 21, 2026, marking the company's first active-active, all-flash NVMe storage system. Synology launched the PAS7700 as field-proven for high reliability and performance while helping customers lower total cost of ownership, with the system delivering up to 2 million IOPS at sub-millisecond latency and throughput up to 30 GB/s. The platform supports file and block protocols including NVMe-oF, iSCSI, Fibre Channel, SMB, and NFS, and includes built-in data protection tools such as immutable snapshots, Snapshot Replication, and Hyper Backup without additional licensing fees.
The PAS7700 was initially unveiled by Synology on May 21, 2025, with Kenneth Hsu, Director of the System Group, describing it as the culmination of 25 years of engineering experience in data management. Synology positioned the PAS7700 to deliver ultra-high performance at a price point previously unseen in the enterprise storage market, combining dual controllers with 48 NVMe SSD bays in a 4U chassis that scales to 1.65 PB of raw capacity with seven expansion units. The system features both inline and offline deduplication to balance efficiency and performance, and upcoming support for Synology Tiering will automatically allocate cold data to lower-cost storage based on customizable policies.
The Synology PAS7700 operates as a 4U system with 48 front-accessible 2.5-inch U.3 NVMe SSD bays and two controller modules in one chassis, distinguishing it from traditional NAS products. The PAS7700 represents Synology's serious entry into enterprise primary storage for organizations whose VMs, databases, AI, or production workflows require continuous service, with active-active controllers, redundant paths, NVMe-oF, and rolling updates addressing requirements a normal NAS cannot fully meet. The system is backed by Synology's 5-year limited warranty and supports up to 2,048 GB of memory across both controllers with optional 100GbE networking for high-bandwidth connectivity.
Synology demonstrated that its PAS7700 all-NVMe storage system maintains zero-downtime continuity during simulated hardware failures. By utilizing an active-active dual-controller architecture, the system prevents service stuns during faults. This capability is critical for data-heavy streaming and virtualization environments, offering high availability while reducing total cost of ownership through a no-license policy.
The PAS7700 uses an active-active dual-controller architecture, which allows for instant failover of IP addresses without interrupting user file transfers or causing the service stuns typical of active-passive configurations.
No, Synology maintains a no-license policy for enterprise features on the PAS7700, including built-in data protection tools like immutable snapshots, Snapshot Replication, and Hyper Backup.
The PAS7700 delivers up to 2 million IOPS at sub-millisecond latency and throughput reaching up to 30 GB/s.
The Synology PAS7700 reached general availability on May 21, 2026.
