About the HPE ProLiant DL20 Gen11

The HPE ProLiant DL20 Gen11 is HPE's densest and most affordable entry rack server, designed specifically for workloads where space and budget are constrained. In a compact 1U chassis, it accommodates Intel Xeon E-2400 series processors, DDR5 memory, PCIe Gen5, and HPE iLO 6 remote management — providing a capable, manageable platform for branch offices, edge deployments, and SME environments.

Processor options span from the Pentium Gold G7900 for light workloads to the Intel Xeon E-2488 (8 cores, 3.2 GHz, 95W) for more demanding applications. All E-2400 series processors support DDR5 memory at up to 4800 MT/s, delivering a bandwidth improvement over previous DDR4-based platforms and enabling more responsive virtualisation and database workloads within the entry-tier segment.

Storage flexibility is handled through 4 SFF or 2 LFF hot-plug drive bay configurations, supporting SAS, SATA, and NVMe drives. The optional HPE NS204i-u NVMe hot-plug boot storage device provides a dedicated OS boot device, freeing primary storage bays for data. Combined with HPE Gen11 storage controllers and Intel VROC support, the DL20 Gen11 provides solid data protection for even entry-level deployments.
