    CPU and System Topology

    Server Description

    A high-density, memory-optimized virtual machine featuring massive RAM capacity and strong multi-core performance for enterprise database and caching workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure M128s is a memory-optimized virtual machine featuring 128 dedicated vCPUs across 64 physical Intel Xeon 8280M cores running at 2.7 GHz. It is equipped with 2048.0 GB of RAM and 4194 GB of local SSD storage, operating under the Microsoft Hyper-V hypervisor. Benchmarks indicate a significant performance tradeoff: single-core metrics for processing and compression are in the bottom 10%, whereas multi-core performance and memory bandwidth are highly robust, with large-block memory read and write speeds ranking in the top 10%. This hardware profile makes the M128s highly effective for memory-intensive enterprise databases, Redis caching, and multi-threaded data processing. However, it is less efficient for single-threaded applications or real-time LLM text generation. Qualitatively, its high memory density offers strong consolidation value for large-scale database workloads.

    Workload Profiles

    3.2Score
    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.
