    Server Description

    A storage-optimized virtual machine featuring massive local capacity, dedicated AMD EPYC processors, and balanced memory-to-core ratios for database workloads.

    Storage & DatabaseMemory Optimized

    Microsoft Azure L12aos_v4 is a storage-focused virtual machine powered by an AMD EPYC 9V74 processor operating at 3.7 GHz. It features 12 dedicated vCPUs, 96.0 GB of RAM, and a substantial 8639 GB of local storage with Premium Storage capability. Running on the Microsoft Hyper-V hypervisor, this instance delivers strong single-core CPU and text processing performance, placing in the top 25% of benchmarks. However, its uncached large-block memory read bandwidth is a notable tradeoff, ranking in the bottom 25%. With a 1:8 vCPU-to-RAM ratio and massive local storage, the L12aos_v4 is highly suited for database operations, large-scale text processing, and storage-intensive workloads.

    Workload Profiles

    0.742Score
    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.
