Description
The Synology DX1215II is a robust 12-bay expansion unit designed to scale your storage capacity without interrupting existing services. Engineered for high-demand environments, it offers a plug-and-play setup that instantly adds up to 12 additional 3.5-inch or 2.5-inch SATA drives to your Synology NAS. With its 550W internal power supply and redundant cooling, it ensures that your growing data needs are met with enterprise-grade stability and performance.
This product is for:
- Enterprise IT Managers: Professionals needing to scale storage for large-scale virtualization or database backups without replacing existing hardware.
- Creative Studios: Video production houses requiring massive, high-speed storage volumes for 4K/8K raw footage and long-term archiving.
- Surveillance Operators: Organizations managing extensive IP camera networks that need to extend recording retention periods across multiple drives.
- Data Center Architects: Users looking for a cost-effective way to expand Synology FlashStation or DiskStation units via high-bandwidth InfiniBand cables.
- Small to Medium Businesses (SMBs): Growing companies that started with a 12-bay NAS and now require a seamless path to 24 bays as their digital footprint expands.

Setting up the DX1215II is remarkably straightforward thanks to its plug-and-play architecture. Once connected via the included InfiniBand cable, the additional drives appear in Synology DiskStation Manager (DSM) as if they were internal to the main unit. This allows for the creation of massive single volumes or separate storage pools. The unit operates quietly at 27.2 dB(A), making it suitable for office environments, while the deep integration with Synology enterprise HDDs ensures firmware updates can be managed directly through the DSM interface, reducing maintenance downtime.
Compared to the previous DX1215, the DX1215II offers improved compatibility with the latest generation of Synology enterprise drives and updated power efficiency. While smaller expansion units like the DX517 are suitable for home or small office use, the DX1215II is built for the FS and high-end DS series, offering more than double the bay count and a significantly more powerful 550W internal power supply. Its use of InfiniBand rather than eSATA provides the higher bandwidth necessary for multi-user environments and heavy I/O tasks.
Q&A:
- How do I connect the DX1215II to my Synology NAS?
The unit connects using the provided high-speed InfiniBand cable. Simply power down the main NAS (if required by the specific model), connect the cable to the expansion ports on both devices, and power them back on.
- Does the DX1215II support hot-swapping drives?
Yes, the DX1215II fully supports hot-swappable drive trays, allowing you to replace or add drives without shutting down the system, ensuring continuous uptime.
- Can I create a single volume that spans across the NAS and the DX1215II?
While DSM allows for spanning volumes across units, Synology recommends creating separate storage pools on the expansion unit to ensure better system performance and data protection in case of cable disconnection.
- What is the maximum storage capacity supported?
The total capacity depends on the drives used and the maximum volume size supported by your primary Synology NAS model. It supports the latest high-capacity 18TB+ enterprise SATA drives.
- Is the power supply user-replaceable?
The DX1215II features a high-output 550W internal power supply. While not a hot-plug redundant module, the unit is designed for easy servicing, and the system fans are also user-replaceable.
