This is the Synology RackStation Xeon D-1541 2.1GHz NAS storage system, order code RS3621XS+. Daisy-chain limits and cable type decide how many shelves a controller can carry and in what order they are cabled. Send the current layout and we will map the cabling with the quote.

What you get ordering this from us
Ordered by part number
RS3621XS+ is what is quoted and RS3621XS+ is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Carriers counted with the drives
Enclosure, carriers and disks are quoted as one line so the shelf can actually be populated on arrival.
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 RS3621XS+ genuine and is the warranty intact?
- Yes. It ships new in Synology packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will RS3621XS+ 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.
