Which server platform choice best targets dense VDI in a traditional design?

The HPE ProLiant DL380 is an industry-standard 2U rack server renowned for its versatility and scalability, making it an ideal platform for dense VDI workloads in a traditional data center design. It provides a robust and balanced architecture, supporting dual high-core-count processors, a large memory footprint, and, crucially, a wide range of GPU accelerators. This balance is essential for supporting a high number of concurrent virtual desktops, from task workers to power users requiring graphics-intensive applications, ensuring a responsive user experience. Its expandability allows for scaling resources as VDI demands grow, fitting the requirements of a dense deployment perfectly.

B. ProLiant MicroServer: This is an entry-level server for small offices with insufficient CPU, memory, and expansion capabilities for any high-density workload like VDI.
C. Apollo liquid-cooled HPC nodes only: Apollo systems are specialized for High-Performance Computing (HPC). While powerful, they are not the primary or most cost-effective choice for a traditional VDI design.
D. Only Synergy frames without GPUs: Modern dense VDI heavily relies on GPU acceleration for an acceptable user experience. A solution explicitly excluding GPUs is unsuitable for this workload.
