Rack server HP Enterprise ProLiant DL340 Gen12 6515P 2.3GHz 16-core 1P 1×64GB DDR5 8×SFF MR416i-o 2×1000W PS EU

HPE ProLiant Compute DL340 Gen12 6515P is a 2U, single-socket rack server designed for data- and storage-centric workloads that require more PCIe lanes and efficient thermal management. The server supports three CTO chassis options (SFF, LFF, and GPU) and features a 3-box modular front design for flexible configuration. It is powered by Intel Xeon 6-family processors, supports up to 144 cores per socket, DDR5 memory up to 4 TB at 6400 MT/s, and PCIe Gen5 connectivity, making it suitable for Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) deployments where single-socket performance and datacenter efficiency are priorities.

Advantages

The DL340 Gen12 delivers higher single-socket performance with Intel Xeon 6 processors and increased memory bandwidth and capacity thanks to DDR5 support. Its 2U chassis is optimized for improved thermals and reduced power consumption compared with less efficient designs, while the modular front and multiple chassis options enable tailored storage and GPU configurations. Redundant 1000 W power supplies and industry-standard rack form factor simplify integration into existing datacenter infrastructures.

Suitable for

• IaaS, PaaS and SaaS hosting environments
• Database and storage-centric workloads requiring more PCIe lanes
• Single-socket compute use cases where density and power efficiency matter
• GPU-accelerated tasks when configured with the GPU-capable chassis

How to use

Install the DL340 Gen12 into a standard 19-inch rack using the appropriate rail kit. Configure the chassis option (SFF, LFF or GPU) based on required storage density or accelerator needs. Populate memory and storage according to workload requirements, and install the operating system and hypervisor of choice. Connect redundant power supplies to separate power circuits and attach network interfaces to your switch infrastructure. Use HPE management tools to configure firmware, monitor thermals, and apply best-practice BIOS and firmware settings for performance and power efficiency.

Recommendations

For optimal datacenter efficiency, choose the chassis and drive configuration that matches workload I/O and capacity needs, enable platform memory speed and power-management settings appropriate for your performance targets, and place redundant power supplies on separate circuits. Use the GPU-capable chassis only when accelerators are required to avoid unnecessary power draw and thermal load.
