HPE ProLiant DL20 Gen10 — Full Technical Specifications

The depth figure in the dimensions row is the shortest of any rack server we list, and it is the reason this model gets specified — it fits cabinets that nothing else fits. Check it against the rack before looking at anything else. The memory row uses unbuffered modules and stops early, which is the hard ceiling of this class and cannot be raised. Drives are few in either format, with a separate boot device listed, which is the sensible arrangement here. The supply row is the one place this small machine can be made resilient, and the redundant option is worth its cost at an unattended site.
