    Server Description

    A memory-intensive server combining a high-frequency Intel processor, massive memory capacity, and local storage for demanding database and enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX48-12mds_v2 is a memory-optimized server from the FXmdsv2 family, powered by a dedicated Intel Xeon 8573C processor with 6 physical cores and 12 vCPUs running at 4.2 GHz. It features an exceptionally high memory capacity of 1008.0 GB, providing 84.0 GB of RAM per core, alongside 2835 GB of local storage. In benchmark testing, the server excels in single-core operations, achieving top-tier results in Geekbench single-core and text processing tests, alongside strong single-threaded compression performance. Multi-core benchmarks and memory bandwidth fall into the average range, reflecting a design that prioritizes massive memory capacity and high single-thread clock speeds over massive parallel core counts. This configuration is highly suited for memory-intensive workloads, in-memory databases, and enterprise applications requiring substantial RAM-to-vCPU ratios without the need for extensive multi-threaded scaling.

    Workload Profiles

    1.33Score
    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.
