Synology has unveiled its most ambitious enterprise storage lineup yet—the PAS Series—marking a serious step up in its capabilities for handling high-performance, mission-critical workloads and large-scale enterprise storage deployments. Featuring two models—the PAS7700 and PAS3600—this series aims to cater to both primary and secondary storage needs with a clear focus on uptime, scalability, and performance.
Unlike Synology’s traditional NAS systems that often strike a balance between consumer and SMB features, the new PAS Series plants a firm flag in enterprise territory, delivering non-disruptive operations, dual-active architecture, and petabyte-scale expandability.
Meet the PAS7700 and PAS3600
Let’s start by breaking down the two SKUs. The PAS7700 is Synology’s flagship offering and is engineered for primary storage in mission-critical environments such as ERP, CRM, and high-frequency transaction processing. Its defining features include an end-to-end NVMe architecture and dual-active controller design, both of which ensure minimal latency and consistently high throughput.
On the other hand, the PAS3600 is optimised for secondary workloads—think file storage, backups, and block storage needs—where cost-effectiveness is key. It still retains the new dual-active, non-disruptive OS but swaps out NVMe for SATA drives, making it more budget-friendly while maintaining high availability.
Both systems run Synology’s newly rearchitected operating system that is designed for always-on uptime. This includes non-disruptive firmware updates, intelligent load balancing, and software-defined failover to ensure that updates or maintenance don’t impact ongoing operations.
It’s all NVMe inside the PAS7700
If you’re wondering where all the performance talk leads, the PAS7700 comes ready to impress. It supports over 2 million 4K random read IOPS, making it one of Synology’s most powerful storage systems to date. Designed to eliminate bottlenecks in storage performance, the PAS7700’s end-to-end NVMe build allows it to sustain ultra-low latency and massive throughput even during demanding operations like AI model training or real-time data analytics.
It’s no slouch in scalability either. With support for up to 7 expansion units, you’re looking at 216 NVMe bays and over 1.6 PB raw capacity (expandable to 9 PBe effective with typical data reduction). It’s an architectural leap that signals Synology is ready to compete in the upper echelons of enterprise storage, especially given the system’s 5:1 typical data reduction ratio under virtualisation and compression-heavy workloads.
Built for Enterprise-Class applications
Whether you’re running a high-frequency trading database or scaling a multi-node Kubernetes deployment, the PAS Series offers performance and availability guarantees essential for enterprise IT.
The PAS7700’s Active-Active configuration means that all controllers are processing workloads simultaneously, increasing resource utilisation and resilience. Meanwhile, interface-level failover ensures that even if a network port or path goes down, your services stay uninterrupted.
Workloads in virtualisation—a traditional stronghold of SAN and HCI solutions—are also covered, with certifications for mainstream hypervisors, support for block and file services, and fast, incremental backup capabilities.
And it’s not just about raw throughput—though it does deliver 30 GB/s+ throughput for 64K blocks—it’s about predictability. In AI and ML scenarios, for instance, where model performance can be severely affected by inconsistent I/O access times, the PAS7700’s architecture ensures sustained, high-speed data flow to keep training and inference cycles tight and efficient.
Data protection without compromise
Security has also been given significant attention. The PAS Series employs a multi-layered protection model comprising Synology’s self-encrypting drives (SEDs), software-based encryption, data immutability, and cloud-augmented threat intelligence. This means that whether you’re fending off ransomware or planning long-term data archiving, the system is designed to keep your data out of harm’s way.
Moreover, Synology has finally introduced a fleet management layer, allowing enterprises to monitor, update, and manage multiple PAS units from a single centralised console. For multi-site operations or businesses with growing data centre footprints, this addition brings welcome simplicity and operational consistency.
Always-on infrastructure
One of the more significant talking points is the non-disruptive architecture. Firmware updates, system patches, and even controller-level maintenance can now occur without taking services offline. This “always available” design is essential for industries like finance, healthcare, and e-commerce, where downtime can translate to significant revenue loss or even legal repercussions.
Load balancing, hardware redundancy, and hot-swappable components are part of the mix, but the big story is how the new OS works in tandem with the hardware to enable these capabilities without operator intervention.
Enterprise Muscle with Synology DNA
The PAS Series is a clear indication that Synology is no longer content with just playing in the SMB and prosumer sandbox. The PAS7700, in particular, is built for large-scale enterprise deployments that demand low latency, high throughput, and zero downtime. With support for NVMe end-to-end, 100GbE and Fibre Channel networks, and robust virtualisation features, it positions Synology squarely against enterprise incumbents.
Meanwhile, the PAS3600 provides a more accessible option for organisations that want many of the same benefits, minus the NVMe tax, making it suitable for archiving, secondary workloads, and disaster recovery setups.
For those who have traditionally looked at Synology for its ease of use and DSM ecosystem, but found its performance tiers lacking for heavy-duty workloads, the PAS Series could be the answer. It’s high performance, high availability, and high capacity—delivered with the familiar Synology software touch.
