What does the HPE Apollo kl20 server support that makes it appropriate for HPC clusters?

Question

Options

• AHPE NVDIMMs
• B24 SFF drive bays
• CDual-port 10GigE integrated network
• DIntel Phi processors

Explanation

D (Intel Phi processors) is correct because the HPE Apollo KL20 was specifically architected to support Intel Xeon Phi (Knights Landing) processors, which feature up to 72 cores designed for massively parallel workloads - the defining characteristic of HPC cluster computing. This dense, thermally optimized design makes the KL20 purpose-built for scientific simulation, modeling, and parallel computation.

Why the distractors are wrong:

• A (HPE NVDIMMs): NVDIMMs are persistent memory modules found in HPE ProLiant and some other platforms, not a defining HPC feature of the Apollo KL20.
• B (24 SFF drive bays): High local storage density suits storage-heavy workloads but is not an HPC differentiator; HPC nodes typically rely on parallel file systems, not local drives.
• C (Dual-port 10GigE): While networking matters in clusters, HPC environments favor InfiniBand or higher-bandwidth interconnects - 10GigE integrated NICs are standard in general-purpose servers, not an HPC-specific feature.

Memory tip: Think "KL20 = Phi for HPC" - the "KL" hints at Knights Landing, the Intel Xeon Phi architecture. Whenever you see Intel Phi + density + parallel workloads, that's your Apollo KL20 signal.
