Do you need a 2U single-socket server that highlights reduced power consumption and better thermals for your data and storage-centric workloads that need more PCIe lanes?
Do you need a 2U single-socket server that highlights reduced power consumption and better thermals for your data and storage-centric workloads that need more PCIe lanes?
The HPE ProLiant Compute DL340 Gen12 is a 2U single-socket (1P) rack server built for data- and storage-centric workloads that need more PCIe lanes. It offers three CTO chassis supporting SFF, LFF, and GPU configurations. The 3-box modular front design enhances configuration flexibility while the energy efficiency of a 2U chassis reduces power consumption and improves thermals—making it ideal for Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) workloads.
Powered by Intel® Xeon® 6 processors with up to 144 cores, increased memory capability (up to 4 TB DDR5), and high-speed PCIe Gen5, the HPE ProLiant Compute DL340 Gen12 server is an excellent 2U single-socket performance solution driving better datacentre efficiency.

- HPE iLO 7 with quantum-resistant (PQC) algorithms and silicon root of trust.
Next-Level Security, Chip to Cloud
From silicon to software, from factory to cloud, and from generation to generation, HPE ProLiant Compute Gen12 is engineered with a fundamental security approach to defend against increasingly complex threats through an uncompromising commitment to constant security advancements.
Silicon root of trust by HPE establishes a zero-trust security framework at the silicon level to ensure firmware integrity. Continuous protection detects compromised servers and prevents them from booting if malicious code is found. Edge servers are safeguarded with default IDevID certificates.
HPE ProLiant Compute servers provide automated recovery from a security event, including restoration of validated firmware, and facilitating recovery of operating system, application and data connections, providing the fastest path to bring a server back online and into normal operations.
HPE iLO 7 supports quantum-resistant (PQC) algorithms and signs HPE ProLiant Compute Gen12 firmware with algorithms approved by CNSA 2.0, enhancing resilience against potential future attacks by quantum computers.
Optimised Performance for Your Workloads: Accelerated, Open, and Efficient
The HPE ProLiant Compute DL340 Gen12 server is an excellent choice for data and storage-centric workloads that need more PCIe lanes, as well as cloud-native, containerised, and scale-out environments requiring high core density.
Powered by Intel® Xeon® 6 processors that support up to 144 cores, the DL340 Gen12 delivers major compute performance over previous single-socket platforms.
Enjoy advanced data transfer rates and higher network speeds from the PCIe Gen5 serial expansion bus, with up to 6 x16 PCIe Gen5 and 2 x16 OCP slots to improve I/O throughput and reduce latency.
