    Server Description

    A high-frequency, memory-intensive virtual machine featuring one terabyte of RAM and fast local storage for demanding database and enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX48mds_v2 is a memory-optimized virtual machine featuring 48 dedicated vCPUs and 1008.0 GB of RAM, powered by an Intel Xeon 8573C processor running at 4.2 GHz. Built on the x86_64 architecture and managed via Microsoft Hyper-V, this instance includes 2835 GB of local storage and supports Premium Storage. It delivers strong memory performance, with uncached large-block read bandwidth reaching 330.82 GB/sec and Redis SET operations exceeding 74.99 million operations per second. The processor supports advanced instruction sets, including AVX-512 and Intel AMX, which contribute to top-tier Geekbench single-core and image processing scores. Lacking a dedicated GPU, the server relies on its high-frequency CPU and massive memory footprint to handle demanding workloads. It is highly suited for memory-intensive databases, large-scale in-memory caching, software compilation, and enterprise data processing.

    Workload Profiles

    3.79Score
    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.
