    Server Description

    A memory-dense x86_64 platform featuring two terabytes of RAM and massive local storage for highly parallelized, memory-intensive enterprise workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure M128 is an x86_64 memory-optimized server powered by an Intel Xeon 8280M processor with 128 dedicated vCPUs across 64 physical cores. Operating at 2.7 GHz under Microsoft Hyper-V, it features 2048.0 GB of RAM (16.0 GB per core) and 14680 GB of local storage, without GPU acceleration. Performance benchmarks reveal a clear tradeoff: single-core metrics and single-threaded compression rank in the bottom 10%, whereas multi-core capabilities and memory bandwidth are highly competitive. Specifically, large-block read-only memory bandwidth reaches a top-tier 426.47 GB/sec, and multi-core CPU tests place in the top 25%. This profile makes the M128 qualitatively cost-efficient for memory-dense, highly parallelized workloads. It is best suited for large-scale databases, multi-threaded data processing, and memory-intensive enterprise applications, rather than single-threaded operations or real-time LLM text generation.

    Workload Profiles

    3.18Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
