    Server Description

    A large-capacity storage and memory-optimized server featuring dedicated AMD EPYC processing and extensive local storage for demanding database workloads.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    Microsoft Azure L48as_v4 is a storage-optimized server instance featuring 48 vCPUs and 24 physical cores powered by an AMD EPYC 9V74 processor running at 3.7 GHz. Built on the x86_64 architecture under Microsoft Hyper-V, it delivers 384.0 GB of RAM and 11519 GB of local storage with Premium Storage capability. Benchmark results show strong performance in multi-core CPU execution, software compilation, and Redis SET operations, placing in the top 25%. Cached memory bandwidth is highly efficient, though uncached large-block memory transfers and database operations perform at average levels. Lacking dedicated GPU hardware, the instance is highly capable for large databases, data warehousing, and memory-intensive enterprise applications, but exhibits poor performance for large-scale language model text generation.

    Workload Profiles

    2.16Score
    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.
