Synology Introduces PAS7700, the Most Powerful Enterprise Storage System in the Company’s History

Synology has globally unveiled the PAS7700, a new high-performance enterprise storage platform marking the company’s entry into the top-tier active-active enterprise storage segment. The new model is part of the newly introduced Parallel Active Station (PAS) series and represents Synology’s most ambitious solution to date for mission-critical environments and demanding workloads.

The PAS7700 comes in a 4U form factor and is based on an active-active architecture featuring two separate 2U controllers, each powered by an AMD EPYC 7443P 24-core processor. The system supports up to 1 TB of DDR4 ECC memory per controller, while storage capacity includes up to 48 U.2/U.3 NVMe SSDs, expandable to a total of 216 drives using additional expansion units.

Particular emphasis has been placed on performance and network connectivity. The PAS7700 supports up to four 100GbE ports, twelve 25GbE connections, and Fibre Channel options, making it suitable for applications requiring extremely high throughput and low latency. According to Synology, the system can deliver up to two million 4K random read/write IOPS and up to 30 GB/s sequential read throughput, placing it among the fastest solutions in the company’s portfolio.

At the same time, Synology introduced the new PAX224 expansion unit with 24 NVMe bays, along with SPU7200D U.3 NVMe SSDs specifically designed for the PAS7700 platform. The new self-encrypting SSD models are available in capacities ranging from 1.92 TB to 7.68 TB, offering up to 140,000 4K write IOPS performance.

The PAS7700 was not developed solely for conventional data storage, but also for modern enterprise workloads such as virtualization, AI analytics, real-time data processing, and Kubernetes environments. The system supports NVMe-FC, NVMe-oF, SMB, NFS, and iSCSI protocols, while integration with the Kubernetes CSI driver enables easier management of persistent storage environments.

An important part of the new platform is DSM Enterprise, a specially adapted version of Synology’s operating system developed for the PAS series. The system includes support for active-active operations, live firmware and software updates without downtime, advanced data deduplication, RAID-TP protection, and a BTRFS architecture designed to preserve data integrity.

Particular attention is given to the platform’s “zero-downtime” policy, under which all software, firmware, and application updates are performed without interrupting service availability. During the upgrade process, workloads are automatically shifted between controllers, ensuring uninterrupted operation in enterprise environments where downtime is unacceptable.

In terms of capacity, the PAS7700 can deliver up to 1.65 petabytes of raw storage, while Synology estimates that with deduplication and data optimization, the effective capacity can reach as much as 8.25 petabytes. The system is also designed for maximum resilience, allowing operation even in the event of up to three drive failures without data loss.

Alongside the PAS7700, Synology also announced the more compact PAS3600 system, scheduled to arrive later this year. The new model will use SATA drives and is intended for organizations looking for a more cost-effective entry point into the PAS ecosystem.
