Dell PowerEdge R550 — Full Technical Specifications
The R550 is the storage-minded member of Dell's fifteenth-generation rack line: a taller chassis than the R450, more bays, and expansion aimed at controllers rather than accelerators. It suits file servers, backup targets and the mid-sized virtualisation host that also has to hold its own data.
Listed as a new build to order and as a refurbished unit.

Full Specifications
The last row of the table is the one that decides most arguments about this model: accelerators are not supported, full stop, and no riser or supply option changes that. Read it early and rule the machine in or out. What you get instead is in the bay row and the controller row — a generous drive count in either format and a wide choice of controllers, including external ones for a shelf. Memory tops out lower than the flagship of the same generation, which is the trade for the bays. Networking adds an optional OCP seat to the onboard pair rather than replacing it.
