ProLiant is the second pillar of the used-server market. Its generation labels (Gen9, Gen10…) map cleanly to CPU and memory platforms — once you know the map, spec-matching is fast.
Knowledge pages are educational references, independent of sales inventory. Items without confirmed sourcing are reference-spec — quoted on demand.
DL = rack (DL360 is the 1U workhorse, DL380 the 2U), ML = tower, BL = blade. The number encodes class, and the generation suffix (Gen9, Gen10, Gen10 Plus, Gen11) tells you the platform: it is the HPE counterpart of Dell's 13G/14G/15G/16G.
| Generation | Key models | CPU platform | Memory | Years |
|---|---|---|---|---|
| Gen9 | DL360/DL380 Gen9 | Xeon E5-2600 v3/v4 | DDR4-2133/2400 · 24 slots | 2014–2017 |
| Gen10 | DL360/DL380 Gen10 | Xeon Scalable 1st/2nd Gen | DDR4-2666/2933 · 24 slots | 2017–2021 |
| Gen10 Plus | DL360/DL380 Gen10 Plus | Xeon Scalable 3rd Gen | DDR4-3200 | 2021–2023 |
| Gen11 | DL360/DL380 Gen11 | Xeon Scalable 4th/5th Gen · EPYC | DDR5-4800+ | 2023– |
Most HPE ProLiant DDR4 platforms take exactly the modules we stock — see 32GB DDR4 ECC RDIMM availability or use the DDR4 compatibility table.
