Dell PowerEdge R840 — Full Technical Specifications

The R840 is a four-socket server in a chassis only as tall as an ordinary two-socket machine — Dell's answer for estates that wanted four sockets without giving up a third of a cabinet per server. It goes to database consolidation and to in-memory workloads where the memory count is the requirement.

It is sold here as a new build, and refurbished units appear as four-socket estates consolidate further.

Full Specifications

Four sockets in this height has consequences, and the table names them. Start with the supply row, which runs to very high ratings: four processors and a full memory complement in a shallow chassis draw more than most cabinets allocate per position. Then the memory row, which is the reason to buy the machine at all — the slot count is the product, and a half-populated one has spent money on the wrong thing. The bay row is small for the chassis because storage is expected to be elsewhere, and the external controller listed below it is the intended route. Depth and weight both exceed the ordinary and belong in the site check.
