    CPU and System Topology

    Server Description

    A high-capacity storage and memory-optimized platform featuring dedicated AMD EPYC processors for demanding database and data-intensive enterprise workloads.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    The Microsoft Azure L64as_v4 is a storage and memory-optimized virtual machine featuring 64 dedicated vCPUs and 512 GB of RAM, powered by an AMD EPYC 9V74 processor running at 3.7 GHz. Built on the x86_64 architecture, this Hyper-V-managed instance includes 15,359 GB of local storage with Premium Storage capabilities. Benchmark results indicate top-tier multi-core performance, with strong ratings in database operations, Redis SET transactions, and static web serving. While memory bandwidth for small-block cached reads is strong, uncached large-block reads perform at an average level. The server's high storage-to-vCPU density and balanced memory allocation make it qualitatively cost-effective for data-intensive workloads. It is highly recommended for large databases, high-throughput web serving, and memory-intensive enterprise applications.

    Workload Profiles

    2.75Score
    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.
