Product overview
Synology lists DX517 as a 5-Bay expansion unit (eSATA, for DS1621+/DS1817+/DS1517+ etc.). An expansion shelf has to be supported by the head unit's firmware, not merely cabled to it. This chassis takes 5 drives. Tell us the controller and we will confirm the shelf is on its supported list.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
Quoted and supplied against DX517 specifically, so what arrives is what your build sheet asks for.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is DX517 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 DX517 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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.
