Synology SA3200D RackStation NAS – Specifications and Data Sheet

Maximize Service Availability, Minimize Downtime – The SA3200D RackStation NAS

Synology SA3200D features a dual controller architecture to ensure operations and core business functions are not severely impacted by a disaster or unplanned incident that take critical systems offline. The hardware redundancy mechanism leverages controllers, power supplies, and fans to prevent a single point of failure. Powered by the intuitive and feature-rich operating system DiskStation Manager (DSM), SA3200D provides comprehensive protection for network, file services, and applications.

Synology SA3200D NAS Highlights

  • Active-passive dual controller design in a single chassis, maximizing service availability with minute-level failover time
  • Highly available infrastructure with a competitive price-performance ratio of US$0.05 per gigabyte
  • A scalable shared storage architecture of more than 500 TB raw capacity with minimal performance impact
  • Automatic failover mechanism, protecting services in real-time and prevent a single point of failure
  • Easy to deploy and manage data services intuitively with DiskStation Manager (DSM), providing a unified experience across Synology platforms and support comprehensive software applications
  • Certified virtualization solution with license-free workload protection

Synology SA3200D – Designed with High Availability and Scalability in Mind

Underneath the 2U chassis are dual controller modules in an active-passive architecture, each connected to the other by the reliable, high-speed Non-Transparent Bridge (NTB) with low latency. The Synology SA3200D is a cost-effective yet highly available data management solution for enterprises, with a competitive price-performance ratio of $0.05 per gigabyte. Service continuity is also backed up by the hardware redundancy mechanism of modularized power supplies and fans to prevent a single point of failure. With SA3200D, you can start small and grow in the future. It supports up to 12 x 3.5″/2.5″ SAS interface drive slots by default, and the capacity can be further scaled up to 576 TB using two RXD1219sas expansion units, with minimal performance impact3. Data replication is not needed for the shared storage design, saving valuable rack space and network bandwidth when compared with two devices using Synology High Availability.

SA3200D Real-Time Protection with Automatic Failover – Active-Passive Explained

With an active-passive design consisting of dual controller modules and the built-in Synology High Availability (SHA) service, SA3200D is built to provide real-time, system-level protection to maximize service
availability. It actively monitors network status and critical file services of CIFS, iSCSI, AFP, FTP, NFS, and Synology Directory Server. Once a controller module or the service is unavailable, the system will fail over
automatically within a minute1 to minimize system interruption and ensure service continuity.

Dual processor architecture

Each controller is powered by an Intel  Xeon  D-1521 processor, providing enterprise-class reliability, availability, and serviceability

Four DDR4 memory slots

8 GB ECC UDIMM, expandable to 64 GB to handle larger workloads

Modular cooling fan

Each controller is equipped with dual modular fans, making maintenance and repair easier


Operating system files are stored separately from general data, providing higher transmission bandwidth and stability

Non-Transparent Bridge (NTB)

Dual-controller connections are faster and less latency

Synology SA3200D Setup – Easy to Deploy, Easy to Manage

SA3200D is designed to help IT administrators easily deploy and manage a highly available data management infrastructure. The system features straightforward, wizard-based GUI setup processes that allow you to build up a highly available service environment within minutes. Service status monitoring is made easy and intuitive. Powered by DiskStation Manager (DSM), an intuitive, user-friendly web-based operating system across Synology hardware platforms, SA3200D provides IT administrators a unified user experience without the need to adapt to different user interfaces and complex configuration settings.
With a full suite of software applications supported in the Package Center, you can download and install a variety of packages including backup, data protection, and virtualization.

The SA3200D Synology RackStation NAS – Built for Your SAN and Virtual Machine Storage Needs

Synology SA3200D provides a fully certified virtualization solution with VMware vSphere™, Microsoft Hyper-V, Citrix XenServer™, and OpenStack Cinder. It supports both iSCSI and NFS protocols
and integrates with VMware VAAI and Microsoft ODX, allowing IT administrators to effectively deploy and facilitate storage operations in various virtualization environments. IT administrators can efficiently
manage virtualized workloads through built-in DSM features and addon plugins for VMware and Windows environments. Features including fast clone, NFS v4.1, and thin provisioning delivers more flexibility to
accommodate to administration needs. With no additional license fees required, your virtualized workload can be further protected by a complete suite of data protection applications including Synology Snapshot Replication, Hyper Backup, and Active Backup for Business to cover various protection scenarios. Synology Virtual Machine Manager (VMM) is an intuitive hypervisor software application allowing you to easily set up virtual machines and run various operating systems, including Windows, Linux, and Virtual DSM.

By integrating the computing and the storage nodes into one system, single-vendor support experience is achieved to lower the management cost. With VMM, each virtual machine can be fully protected by a set of disaster recovery features including instant snapshot, replication, clone, and restore, safeguarding your virtual machines without additional cost.

Synology SA3200D 12-Bay NAS Price and Release Date

We still do not have a concrete idea of when the Synology SA3200D will be released, however as this is a remarkably unique product in the Synology line up (only comparable to the UC3200), I think that this is likely to be a solution for very late into 2019, or more likely Q1/2 2020. It’s increased focus at the Synology Taipei and Berlin event earlier in 2019 and improvements to the software lineup in DSM 7.0 covered in the launch event, only serve to make this even more attractive to businesses. Therefore it’s release will likely be closely linked to the best time for business buyers and their respective start/end of budgets to spend in 2019/2020. Price wish, we are likely looking at £4-5000 at the very least and even then this is rather conservative for a SAS based, twin controller, rackmount NAS Rackmount.

Alternative to the Synology SA3200D RackStation NAS

As stated, the Synology SA3200D is a fantastically unique piece of rackmount storage and therefore hard to compare against the currently Rackstation lineup. If you are looking for a solution right now and the uncertain release schedule of the SA3200D is something you cannot accommodate, then there are already several powerful Rackmount solutions available to you right now. You could look at using the Synology High Availability setup with two RS1619xs+ Rackstation NAS, but this will significantly limit your storage potential compared with the SA3200D Rackstation:

Alternatively, an existing alternative that can achieve a similar hardware architecture to the SA3200D in practice, can be achieved using a combination of expansion storage and the RC18015xs+ in a two-unit setup will also provide a great degree of robust disaster recovery.

Finally, in terms of power and storage, right now the best option that is available to most users in the existing series devices is the RS4017xs+.
