Product overview
This is the Synology 12-Bay rackmount expansion unit, order code RX1217. An expansion shelf has to be supported by the head unit's firmware, not merely cabled to it. This chassis takes 12 drives. Tell us the controller and we will confirm the shelf is on its supported list.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
The order is placed against RX1217, not against a description of it, so there is no room for a substitution you did not agree to.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Supported by the head unit
We confirm the shelf is on the controller’s supported list, not merely that the cable fits.
Questions buyers ask about this part
- Is RX1217 genuine and is the warranty intact?
- Yes — new and sealed, with the Synology warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will RX1217 work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.
