Synology RackStation RS2423RP+II 12-Bay Rackmount NAS Enclosure
Twelve bays, 10GbE built in and two power supplies, in a 2U chassis. AMD Ryzen V1780B at 3.35 GHz with 8 GB of ECC memory, a PCIe slot for 25GbE or M.2 cards, and expansion to twenty-four bays. The RP in the name is the redundant PSU — the unit keeps running when one supply or one feed fails. Supplied without drives.
Quick Glance
Key Features
Two power supplies, not one
The RP suffix is a redundant 550 W power supply. One unit can fail, or one feed can drop, and the RackStation keeps serving — which is the difference between a scheduled repair and an outage. Two power cords ship in the box for exactly that reason.
10GbE on the board
A 10GbE RJ-45 port is built in rather than being an upgrade, alongside two Gigabit ports. The PCIe Gen3 x8 slot is still free for a 25GbE card, a second 10GbE card, or an M.2 adapter for SSD caching.
Twelve bays, twenty-four with expansion
Twelve hot-swappable bays in 2U, doubling to twenty-four with an RX1223RP over Mini-SAS HD. Enough spindles for RAID 6 or SHR-2 with real usable capacity left over.

Need-to-Know
- The RS2423RP+II ships as a bare enclosure. Budget for up to twelve SATA drives on top. Synology's wording for this class is stricter than for its desktop models: it guarantees full functionality only for Synology drives on the compatibility list, and warns that non-validated drives may limit functionality and risk data loss and system instability.
- At 56.2 dB(A) this is rack equipment, not office equipment. It belongs in a comms room, not under a desk.
- Memory is ECC UDIMM, not the SODIMM used across the desktop DiskStations — modules are not interchangeable between them. Both slots must hold identical modules to reach the 32 GB ceiling.
- The rail kit is not included. A 4-post rack needs a Synology RKS-02 sliding rail kit, sold separately, and the chassis is 578 mm deep — measure the cabinet before ordering.
- The operating temperature range stops at 35 °C. In a UAE comms room that makes cooling a design requirement rather than an afterthought.
- The warranty extension for this class is EW202, not the EW201 used on the desktop models. Both are the Asia, Africa and Oceania SKUs; 'Extended Warranty Plus' is Europe and North America only.
Best For / Customer Benefits
Customer Benefits
- A redundant power supply turns a dead PSU from an outage into a scheduled repair.
- 10GbE is built in, so the network is not the bottleneck on day one.
- Twelve bays give RAID 6 or SHR-2 real usable capacity after redundancy.
- Btrfs snapshots roll a share back to a point in time, which is what actually saves you after ransomware.

Frequently Asked Questions
No. It is sold as a diskless enclosure, so you choose the drives to suit the capacity you need. It takes up to twelve 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. Synology's wording for this class is stricter than for its desktop range — it guarantees full functionality only for Synology drives on the compatibility list, and warns that non-validated drives may limit functionality and risk data loss. We are happy to quote validated Synology drives alongside the unit.
Redundant Power. The unit has two 550 W power supplies instead of one, so it keeps running if a supply fails or one mains feed drops. That is why two AC power cords ship in the box — run them to separate circuits or separate UPS units to get the benefit. The RS2423+ is the same machine without that redundancy.
Not for 10GbE — a 10GbE RJ-45 port is built in, alongside two Gigabit ports. The PCIe Gen3 x8 slot stays free for a 25GbE card, a second 10GbE card, or an E10M20-T1 combo card that adds M.2 SSD slots for caching. This model has no onboard M.2 slots, so caching does mean using that slot.
Three things. Depth: the chassis is 578 mm deep and the RKS-02 rail kit is a separate purchase. Cooling: the operating range stops at 35 degrees Celsius, which is a real constraint in a UAE comms room. Noise: at 56.2 dB(A) this is rack equipment and should not go anywhere near a desk.
