HPE ProLiant DL20 Gen11 P83278-005 Xeon 6315P 2.8GHz 4-Core 16GB DDR5 2x1TB SATA rack server

HPE ProLiant DL20 Gen11 1U rack server

This 1U rack server is built for general-purpose workloads in small-to-medium business environments. It ships with a single Intel Xeon 6 6315P processor running at 2.80 GHz with four cores and 12 MB L3 cache. The platform supports a maximum of one processor, so CPU upgrades are not an option. It is designed for standard rack installations where space efficiency matters.

Bundled storage and power supply details

Two 1 TB SATA 6G business-critical 7.2K LFF hard drives are pre-installed and managed by the embedded Intel VROC SATA controller. A single 290 W FIO power supply kit provides power, with no redundant PSU included. The system also includes an embedded 1 Gb 4-port BCM5719 network adapter and three high-performance hot-swap fans for cooling. These components define the baseline storage, networking and power capacity out of the box.

Memory slots and expansion bay limits

The server arrives with one 16 GB DDR5 UDIMM at 4800 MT/s installed in a single slot. Additional memory must match the DDR5 UDIMM specification to be compatible. Only two expansion bays are available in total, and both are occupied by the factory-installed drives. Buyers needing more internal storage or add-in cards must plan around this constraint.
