    Server Description

    A storage-optimized ARM64 platform delivering thirty terabytes of local NVMe SSD capacity and fifty gigabits per second network bandwidth.

    Storage & DatabaseGeneral Purpose

    The Amazon Web Services is4gen.8xlarge is an ARM64 storage-optimized instance powered by a 32-core AWS Graviton Neoverse-N1 processor running at 2.5 GHz. Built on the Nitro hypervisor, it features 192 GB of RAM and an extensive 30,000 GB of local NVMe SSD storage, supported by a 50 Gbps baseline network bandwidth. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 48,576.33 and a Geekbench multi-core score of 11,813.0. However, single-core performance represents a tradeoff, with weak single-threaded compression and low single-core Geekbench scores. This instance provides high storage density and predictable dedicated compute resources, making it highly efficient for storage-intensive applications. It is best suited for large-scale databases, high-throughput static web serving, and data-intensive workloads requiring massive local NVMe capacity.

    Workload Profiles

    1.55Score
    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.
