Dell PowerEdge R420 — Full Technical Specifications

The memory row is the row that dates this machine: it takes DDR3, which no later Dell server does, and the modules for it now come from the same used market as the server. Budget accordingly. The supply row offers redundant and non-redundant options and on a machine this old the non-redundant one is genuinely risky, since a failure means a replacement from stock that is no longer made. The controller row names an early hardware RAID generation whose drives do not carry forward. The management processor is two generations behind current tooling and integrates poorly with it, which is often the practical reason estates finally retire these.
