    Server Description

    A high-capacity storage and memory-optimized platform featuring dedicated AMD EPYC processors and massive local NVMe SSD capacity for demanding database workloads.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    Microsoft Azure L48as_v4 is an x86_64 server within the Lasv4 family, powered by a dedicated 3.7 GHz AMD EPYC 9V74 processor with 48 vCPUs and 24 physical cores. It features 384.0 GB of RAM and a bundled 11,519 GB NVMe SSD, managed by Microsoft Hyper-V. Performance benchmarks place this instance in the top 25% for multi-core CPU execution, software compilation, and Redis SET operations. However, uncached memory bandwidth and database operations perform at average levels, and text generation for large 70B LLM models falls into the bottom 10% due to the lack of GPU acceleration. This hardware profile makes the L48as_v4 highly effective for storage-heavy databases, caching layers, and memory-intensive general-purpose workloads, offering a strong balance of high-capacity local storage and dedicated compute resources.

    Workload Profiles

    2.2Score
    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.
